Not a good idea---- IMHO--tooooo much fuel pressure, requiring a regulator which after two months cratered on mine putting fuel all over where it did not need to be at a high rate.



I kept mine inline but with a switch to turn on or off, as on the first start after its been sitting but with the stock engine driven pump for normal use, but thats why Dave pays taxs, so everyone can do what they like.</font>

As part of the restoration of my car, I am getting rid of the
mechanical fuel pump in favor of an electric. To cover the hole in the
block that the mechanical pump left, I had a local waterjet shop make
up some metal cover plates:

I still need to paint it, but when that is done I will get some
pictures of it attached to the motor.

This is by no means meant as a diss on Peter, but his email got me to
thinking....how many Amphicars truly are "restored"? Are any of them?
Except for the few originals, wouldn't they all fall under the category
of "fixed up" or "customized"? Mine is as stock as they come, but even
it has a non-stock bilge pump.

Thank goodness this particular niche of the automotive universe is not
inhabited by purists!

My guess is the purpose of an electric fuel pump is to avoided vapor lock issues.My other guess is that I have been blessed. I have driven my Amphi on triple digit days over high passes without a problem. However, I became paranoid reading about vapor lockproblemswith Amhpi's that I installed a hi temp heat hose over the fuel line where it passes around the valve cover and over the exhaust manifold. What a dumb F--K'in design.

Which brings me to another thought: How many people drive their Amphi's with low octane fuel? The cheap fuel has a lower boiling point and will vapor lock before a higher octane will.

I run my Amphi on 100LL avgas because my heads haven't been modified with stelite seats and hardened valves yet. 100LL still has a small amount of lead to preserve my valve integrety. Avgas also has an additive which increases the boiling temp of fuel to prevent vapor lock. The boiling temp of fuel decreases as the atmospheric pressure drops. Pretty embarrassing to have an engine quit at altitude because of vapor lock. This has been a HUGE problem in aircraft ever since car fuel has been approved for some airplanes. Dumb idea.

Sure the avgas cost more, but think about it. How many miles do you drive your car a year? 500 miles and 150 in the water? What's the difference in price? $50 maybe?

My 1st suggestion is to switch to a higher grade of fuel if yer not already doing so and see what effect that has on you fuel vapor problem. If thatdoesn't help, I'd suggest going to your local airport and trying some avgas. Bring your 5 gallon jugs. Most airports are prohibited from fueling cars. Some won't want to do your jerry cans. 100LL is very popular with the snowmobilers around heredue to the low vapor pressure of aviation fuel.

High temp motors and vapor lock seem to be a common problem with this car. My Amphi is nearly stock and I have never had a problem with hi tempsor vapor lock.

The price of an electric fuel pump could make up the differencein the priceof avgas over a year.

Sure there's a design flaw in the fuel system. Owners have battled this problem over the years making hideous heat shields and what not to their cars when all they needed may have been a higher grade of motion lotion.

Can the electric pump until you have eliminated all other cures.

I used AV fuel for years in my GTO due to vapor lock, need for higher
octane, etc. Car's & Parts recently did a excellent article on
today's fuels including the use of AV gas. They highly recommended
not using AV fuel in cars as it contains huge amounts of some kind on
antifreeze which can be harmful to automotive engines.

I too think a electric fuel pump is asking for a disaster. The Amphi
doesn't require very much pressure (2 to 3 pounds).

I have never had a overheating or vapor lock issues since my radiator
was recored. On those extremely hot days I have a bilge blower in the
engine compartment that takes the heat right out and makes all run
cooler and start right up, even after shutting it off on a hot day.
Probably wouldn't even need the blower since Amphi doesn't run hot at
all.

I did add a heat shield under the carburetor and did notice a
considerable difference right away. Plus those occasional rare drips
of gas from the carb don't go into the bilge which can be a bad
thing.

Larry,

I have no pictures of the heat shield. Maybe I can take some over the
weekend. I have had this on my Amphi for 3 years.

I went to Wal-Mart and bought a cheap ($4) 4" round baking dish used
for small cakes or pies. The kind that you separate the bottom piece
from the top section which has a snap clip on it. It is made from a
silver hammer-tone finish, made for heat, no paint to run off and gas
won't hurt it.

The bottom piece has a nice rounded lip that prevents gas from
spilling onto the engine / exhaust manifold. It tucks under the carb
quite well. It ends up being a disc with a lip after the top portion
is removed. I used a hole saw to drill a hole the size of the carb
opening plus then drilled the mounting studs. You will need a extra
carb mounting gasket when adding the heat shield.

Baking made easy the Amphi way!

Re: Re: Fuel Pump Cover

Whoa! Antifreeze in AvGas? There's an additive that increases the vapor pressure which increases the temp at which the fuel boils. Vapor lock in airplanes using car gas has been a serious problem. There's also an additive that increases storage life in avgas. I like it because my fuel systems never gum up during winter storagein my various gas driven yardmachines. I have used 2 year old avgas without a problem. My lawn tractor has used it for 15 seasons. The only serious problem I could see with avgas is the lead. Lead will destroy and clog a cadylitic converter in no time. I'm certain that the advantages to avgas usedin early model cars significantly out weigh the disadvantages. I use it primarily for the lead contentwhich lubricatesmy Amphi's valves. I guess there's additives for unleaded fuelavailable which boost octane ratings and lubricate older unmodified valve sea
ts. I've never used it.

Jet fuel uses an optional fuel additve to prevent water from freezing which clogs fuel filters which flames out engines. I guess it could be called an anti-freeze. The additive is used primarily on aircraft not employing a fuel heater. 6 oz's will treat 500 gallons of fuel. Used in larger amounts can damage aluminum components of the fuel system. My diesel Mercedes and Datsun trucklike jet fuel just fine.

I would like to see that article which discourages using avgas in motor vehicles. I've got nothing but positive results from itover 30 years.

Another suggestion is to call the local operator at your airport and ask for line service. Ask what they do with their contaminated fuel. This is the fuel which gets sumped from the trucks on a daily basis. Most operators have to pay somebody to haul it off and are very happy to have someone grab it for free. That's a really good price! The only time I pay for avgas is when I put it in an airplane. Always run contaminated fuel thru a filter as it can and usually does have small quantities of water in it.

p.s. I like your heat shield, Ron! Keep it simple.

I used AV fuel for years in my GTO due to vapor lock, need for higher
octane, etc. Car's & Parts recently did a excellent article on
today's fuels including the use of AV gas. They highly recommended
not using AV fuel in cars as it contains huge amounts of some kind on
antifreeze which can be harmful to automotive engines.

I too think a electric fuel pump is asking for a disaster. The Amphi
doesn't require very much pressure (2 to 3 pounds).

I have never had a overheating or vapor lock issues since my radiator
was recored. On those extremely hot days I have a bilge blower in the
engine compartment that takes the heat right out and makes all run
cooler and start right up, even after shutting it off on a hot day.
Probably wouldn't even need the blower since Amphi doesn't run hot at
all.

I did add a heat shield under the carburetor and did notice a
considerable difference right away. Plus those occasional rare d
rips
of gas from the carb don't go into the bilge which can be a bad
thing.

Re: Re: Fuel Pump Cover

<table>
Whoa! Antifreeze in AvGas? There's an additive that increases the vapor pressure which increases the temp at which the fuel boils. Vapor lock in airplanes using car gas has been a serious problem. There's also an additive that increases storage life in avgas. I like it because my fuel systems never gum up during winter storagein my various gas driven yardmachines. I have used 2 year old avgas without a problem. My lawn tractor has used it for 15 seasons. The only serious problem I could see with avgas is the lead. Lead will destroy and clog a cadylitic converter in no time. I'm certain that the advantages to avgas usedin early model cars significantly out weigh the disadvantages. I use it primarily for the lead contentwhich lubricatesmy Amphi's valves. I guess there's additives for unleaded fuelavailable which boost octane ratings and lubricate older unmodified valve sea
ts. I've never used it.

Jet fuel uses an optional fuel additve to prevent water from freezing which clogs fuel filters which flames out engines. I guess it could be called an anti-freeze. The additive is used primarily on aircraft not employing a fuel heater. 6 oz's will treat 500 gallons of fuel. Used in larger amounts can damage aluminum components of the fuel system. My diesel Mercedes and Datsun trucklike jet fuel just fine.

I would like to see that article which discourages using avgas in motor vehicles. I've got nothing but positive results from itover 30 years.

Another suggestion is to call the local operator at your airport and ask for line service. Ask what they do with their contaminated fuel. This is the fuel which gets sumped from the trucks on a daily basis. Most operators have to pay somebody to haul it off and are very happy to have someone grab it for free. That's a really good price! The only time I pay for avgas is when I put it in an airplane. Always run contaminated fuel thru a filter as it can and usually does have small quantities of water in it.

My approach has been to throw all of the parts I remove from the car

The electric fuel pump is largely for my own peace of mine. When the
car was running I twice found the mechanical one leaking fuel into the
bilge (and onto the electrical connections for the starter!), even
after tearing it apart and rebuilding it. The electrical will let me
reroute the fuel lines slightly to avoid that, and I am using a bypass
regulator so excess pressure does not build up in the fuel lines, and
stress the pump.

I am upgrading a lot of systems on the car in this same vein (electric
fans, electric fuel pump, pertronix ignition, alternator) where I feel
the modern replacement is more reliable or puts less wear on the
engine than the stock part do. I have nightmares about the lever erm
for the fuel pump breaking off inside the block and destroying the
bottom end of the motor, so this lets me sleep a little easier.
