Electric fuel pump suggestions

Joseph_siller · Oct 26, 2017

Hello c10 brothers I own a 1973 c10 with a 350 with a 4 barrel carb and long tube headers. And was wondering if anyone has any suggestions for electric fuel pumps. I'm going to run a Boyd fuel cell underneath the bed and I ordered a fuel pump that a summit racing guy suggested a Holley mighty might and it was to low of a gph and psi. So what do you guys think I should run for my truck. When it comes down to fuel pump and a regulator.

Um, did you actually order the pump and try it?

Phew, carbs need very little fuel pressure. Probably looking at 5 PSI median. That one must have been defective or something. I'm not up to speed on the external electric pumps, but if you don't mind my asking, where do you stand on just a mechanical pump?

OEM style in tank with a return regulator would probably be best.

No I'm currently running a mechanical pump and it's fine but I was told that running an electric pump is better for the long run

I would disagree with that statement. I can't think of one reason that you'd be better off with an electric pump unless your camshaft eccentric was worn out, and the pump wouldn't work. Maybe someone else knows a reason, but I daily drive a car with a mechanical pump, and it's just a sixteen dollar Delphi pump. Works great.

I would never run an electric pump unless I absolutely had to, anything electric is prone to take a **** sooner or later, could work for 20yrs could work for an hour ya never know, except that you know it won't take a **** in your driveway,lol, a good mechanical will pretty much last forever, only downfall to a mechanical is if you drain the system and put the vehicle away for long period of time, just like hoses the diaphragm in the pump will dry up and get brittle without fuel, then the diaphragm won't flex and end up cracking/breaking and quit pumping fuel, there is a fix though, after draining put Marvel in the pump and it'll keep the diaphragm from drying up...

There is always the no manual provision or it just won't fit like where I was at....... :Wedgie:

Does that fuel cell pull from the bottom or top? If bottom I'd say Holley Red pump, no regulator needed. That pump won't last as a puller but works great as a pusher.

I put a sump in my Blazer tank and run a Holley Red pump. People bitch about them and bash them because they burn up then you read that they are using them as pullers. They are not designed for that the need to be fed and are pushers. I rebuilt mine and they sent me a Blue pump rebuild kit which bumps the pressure up so now I have to put a return regulator on not a big deal they live longer with a return style. A dead head regulator puts a lot of strain on a pump.

I have tried the Holley pumps and they don't put out the volume or pressure. I wanted a pump I could use without a regulator.
Back in my racing days I used 2 Carter rotary pumps in parallel, worked great. I now run 1 Carter pump w/ external pressure regulator set for 6 lbs pressure. If you are going to use a pressure regulator, don't buy a cheap Holley regulator they're junk, spend around $100 for a good one.My fuel cell is mounted in the bed and flows gravity from the bottom to a Fram racing filter can and then the pump. Great set up.

Anything is junk when it's installed improperly and not proper for an application.
