Booster Pump

[RUfj40crazy]

I recently picked up a 4 wheel off road mag and read the article on booster pumps; the pump used was a carter p4602rv.

I’ve had problems recently with starting on cold days and more importantly killing the battery trying to turn the engine over after running the tank dry. I assume the routing of the fuel lines is original (from the tank up and across the fire wall and to the driver side fender).

My 40 has a V8 conversion and I was thinking it may be a descent upgrade, not sure if the mechanical pump is working real well or at all.

Anybody ever installed a booster pump in a 40?
Is it worth it?

Fuel line routing not stock at all....


I would figure out why you are loosing fuel from the pump to the carb, where it is going, and would verify that your mechanical pump is working properly..

What is the level of your engine oil?

If I was you, I would just do an electric pump, forget a/b using the mechanical pump and booster pump. My Auto-Tech teacher gave the impression that there is just no reason not to use an electric pump.

Would suggest looking into a fuel regulator, so as to not possibly run into flooding issues...



Good luck!

It seems to get fuel fine.

When I drained the tank to work on the tub I had problems getting fuel to the carb after reinstallation. I had to hook the battery to a charger to turn the engine over enough times to get gas flowing. Er... so it seemed, actually I ended up pulling the air filter and dumping fuel in the carb to get pressure from the cylinders.

I guess I was really getting at; is because of the crappy routing of the fuel lines and the v8 is it worth it to upgrade for wheeling or even daily driving?

I use an electric pump as a booster behind the mechanical pump on my V-8 K5. I run triple fuel tanks, and the switching valve restricts the flow enough to where the mechanical, a high-volume holley, still doesnt always keep up. I have a SW electric fuel pressure guage in the cab to let me know when the pressure has dropped off enough to toggle the electric pump on. Usually only needs a few seconds. Unless I'm in the middle of smoking a FORD!

An electric pump is just one more point of failure - OEM mechanical pumps are more reliable, in my experience, than aftermarket electricals, pretty easy to carry as a spare when out in the boonies, and easy to change, too.

Plus, they stop pumping gas when the engine stops, a safety measure, IMO.
