Fuel Pump Leak !
Posted by: FRANK6969 ()

1963 Spyder, 34k. I Just came back from the shop, and the Winter oil change, filled the gas tank, added some stabel and a bit of carb cleaner to the gas. When I checked the fuel pump I noticed the gasket leaking. Should I just go ahead and order a new fuel pump from Clarks?

I replaced my mechanical fuel pump in the last few months. My 64 starts so much better and runs better that I can not say enough about this changeover. Dump the mechanical pump. I also used toe special casting on the middle of the existing pump so no repiping of gas lines on the engine. Great change!

It's not unusual for them to leak in the Spring and stop after they run for a bit. If you're having trouble in the Fall I would certainly anticipate it will be worse in the Spring.
Clarks pump is at least a little better than local auto parts with less pressure. I would install one of them if someone wants.
Turbo carbs are sensitive to excessive fuel pressure.
In general I've about had it with mechanical pumps though, I've installed several electric fuel pumps this year. I put up the good fight for a few years by changing springs and such but if the castings these days are prone to warping, what's the use? If someone came up with a decent rebuild kit I might consider rebuilding originals.
