'69 Fuel Pump

[hdflh67]

My '69 350/350 has had an aftermarket electric fuel pump added.

Has anyone had any experiences with the original style mechanical fuel pump versus an electric add-on?

I am primarily concerned with reliability and driveability right now.

Thanks and Happy New Year!

Unless you're pushing over 600hp, there's no need for an electric fuel pump and its associated hassle (wiring, plumbing, connections, noise, poor reliability, need for regulators, etc.); an electric fuel pump doesn't add one horsepower - can't imagine why people put them on normal cars. A plain ordinary mechanical pump will work just fine - fed an L-88, didn't it?

Are fuel pumps (specifically mechanical) something that you need to be repairing and/or replacing a lot? I don't see many problems with them around the forums. Just curious...

They are mechanical and will occasionaly fail. Luckly they are easy to replace.

Do they leak at all? Thanks for the reply!

I replaced mine about 1 yr ago. It was fairly simple. One trick that was told to me, was to push the rod up, and tighted down a bolt in the threaded hole. This will keep the push rod up while trying to insert the fuel pump. Trying to do this with out.......tough!
Good luck.

Stallion, like any other mechanical device they do break down from time to time, but they're not something that breaks down often, which is good cuz i dont wanna drop my tank ecery few thousand miles to replace a fuel pump. If you're going for bih HP then you're gonna have to upgrade you're pump in order to supply the engine with the fuel it needs to put out those ponnies...... one thing to remember is that fuel pump is an electric device that generates heat, so its better not to go below the 1/4 of the tank, because then pump works harder and there's no fuel to cool it down.
