I use an electric fuel pump. Will that effectively stop the fuel from siphoning?

Most fuel pumps won't stop the siphoning as they don't have any sort
of valve that closes completely. Only the fuel tap or the shutoff
valve will work. (unless you have a hill to park on rear end up)
I have a electric pump piggy backing the manual pump just in case one
craps out. Redundantcy ... Redundantcy ... Redundantcy.

Even if it does have a built in shut off valve if it's located in the engine
compartment it wont do any good for a fuel line leak between the pump and the
tank.

Re: Re: magneto shut off
You are right Greg, for fuel to leak through the carburetor, the needle valve
would have to leak (or there'd have to be something else leaking).
But, while they usually do a good job, carburetor needle valves were never
really intended to be 100% leak proof. They don't need to be when the engine
is running. Even at idle the engine is using some fuel. So, if the needle
valve leaks 1 drop per minute when closed, the engine will use this fuel
before the carburetor overflows. However, when the engine is off, if the
needle valve still leaks 1 drop per minute, you will have gas in the bilge
before long.
Also, as others have mentioned, having a valve near the tank allows you to
shut off the fuel should the fuel line develop a leak while you are driving.

Re: Re: magneto shut off
Could someone explain how gas can leak through the
carb and into the bilge. Even without the manual
shut-off or magneto? When the carb bowl is full the
manual shut-off on the float stops gas flow the same
as it does when you are idling and the fuel pump is
trying to pump more gas than you need. I'm convinced
my magneto doesn't work because when I disconnected
my fuel line at the fuel pump to replace the pump, the
gas just kept pouring out even with no key in ignition
yet I never have problem with fuel leaking even when
parked on an incline. Wouldn't you have to have a
faulty float valve for gas to leak past it?

Re: Re: magneto shut off
All good points, Roger. I'm definately not comfortable
relying on only the float valve long term and want to
fix my magneto (or whatever we all agree to call it)
valve but I wanted to make sure I understood the
issues. I think good ole' John (always a wealth of
information) B. gave me a clue as to why my mangeto
may not be working. My car has a bilge blower but the
previous owner must have wired around the auto feature
because my car will start instantly and the blower
only works if I manually pull the switch. If the
magneto is wired through the blower "auto" feature as
John suggests and someone wired around the blower to
prevent the wait for starting, I'm thinking the
magento may be receiving current all the time. Maybe I
just need to rewire it to the ignition switch. Any
thoughts on that John?

Greg,
-First you need to ensure your solenoid is getting power and when.
Use a test light hooked up to the leads.
-Turn ign on and see when/if you have power before and after blower
is activated. It should be only after blower is off.
-If you have 12VDC at the solenoid and it not working, then the
solenoid is the probable cause.
-If you do not have power, then you will need to trace it back and
find out why. The factory connection is to the brake light switch (on
the master cylinder) power "IN" (so there is power after blower is
deactivated and not when the brake pedal is depressed).
Alternativley, you can wire it to the ign switch in the "RUN"
position.
If you have 12VDC at the solenoid, remove it and then apply 12V and
listen for the solenoid operation (clicking). I also use about 3-5
LBS (no more!) of air pressure hooked up to it while it is closed and
listen for any leaks. There should be none. Then apply the 12VDC and
see if it opens. If not, it will need replaced.
I hope this helps
John
