Ford 351w Question

Could I use the stock electric pump? I was under the impression they where much higher pressure.

With a carb it isnt about pressure, all you need is 5psi at the carb. for a prerunner id run mechanical, UNLESS, you can afford 2 electric pumps. you can buy a mechanical pump anywhere, electric can be a pain in the ass..

Agreed. The mechanical pump is easy and super cheap. If you get a timing cover for a mechanical pump, make sure you also get the drive that bolts to the front of the camshaft. The EFI engine will not have this.

Will the cam have a lode to run the pump?

The pump doesn't drive off the camshaft itself, there is a piece that bolts to the front of the camshaft that drives the fuel pump.

Run the air gap intake. Electric pump with the regulator next to the carb. Return line larger then the feed line.

Is this the part you are talking about to go on the front of the cam to run the pump?

^^^^ That's it.

Mechanical pump = In theory less to go wrong. No wiring. No fuses/relays. No motors to burn out. No magnets to break. With a mechanical pump if the engine is running the fuel pump is most likely pumping. Lots of the really big HP guys have had great luck (or should I say better luck) with mechanical pumps (Clay Smith comes to mind) than electric pumps.

Mechanical pump downside... If you don't drive the vehicle very often (let's say the bowls go dry) you will have to crank it over and over before the pump can fill the bowls and build pressure. Also, in certain cases the mechanical pumps can heat up and cause vapor lock issues.

With an electric pump you can wire it to an oil pressure safety switch. If you lose oil pressure the switch will kill power to the pump which in turn shuts down the engine. That can be a "safer" setup for you and the engine during the "what-if" we hope never happens.

Get one that needs an external regulator. Circulating fuel is much less prone to boiling..........

Could I do this with the stock pump from when it was efi?
