Fuel pump; mechanical or electric?

[bighammer]

Hi guys… I just came to the realization that my 1991 LA block does not have the lobe on the cam for a mechanical fuel pump. (this was originally a TBI engine) I understand that I can add the part to the cam to make it work but… It would be simpler to simply go with an electric fuel pump. Are there any negative aspects to installing an electric fuel pump versus a mechanical one?

Thanks

biggest problem is almost all electric pumps are noisy

And where to mount

I go a while between drives sometimes, the elec primes my carb for me. I also set it up as an auxiliary kill switch. If they get my car they won't go far.

Untrue. The gerotor style pumps are very quiet, reliable and last a long time. Plus they are also rebuildable.

Safety comes to mind for me. With electric you need an oil pressure switch or I think they now make a tach signal switch.

Ford fuel pump inertia switches are cheap. They can be wired in as well in case of an impact.

the walbro 392 http://www.gsl392.com/ is damn near silant will support over 600 hp and is only 100 bucks and will last a long time .the bad is you will need a bypass regulator and a return line which is easy to do anyway.

and these should always be used it just may keep you from being the main attraction at a weiner roast .

Electric pump in the tank, like what Tanks Inc. http://www.tanksinc.com/ sells works great. Not noisy, eliminates vapor lock, and depending on which pump you get can be adapted for fuel injection, a return fuel system, etc... I put one on my '69 Dart and I'm 100% happy with it!

$235 for their new tank to be out soon. Uses their GPA pump module and you have to use an aftermarket gauge sending unit.

To the OP, just make sure you get a pump for a carburator and not EFI. Pressures are different. In my experience external electric pumps are only really noisy when they cavitate.

Thank you all for the tips. I'm looking at all options at this point!
