In tank fuel pump

Make your Cougar run faster, handle better, and jump higher... okay maybe not jump higher. If you feel the need for speed, this is the place.

In tank fuel pump

Post by DaveK » 20 Dec 2017, 13:20

Sitting here at work with some time on my hands I got to thinking - would it be possible to put an electric fuel pump in the tank of my XR-7 while maintaining the low fuel level sensor?

I think the pump would be easy enough to attach to the pickup tube, however, the question is how to get power to the pump?

So I did a little digging online and found this:

There might be enough space on the mounting flange of the sending unit to mount two of these to power the pump.

What do you guys think?

Is there a better way to get power through the mounting flange?

I've never seen a submersible fuel pump that produced low enough pressure for a carbed engine. Those are designed for efi where fuel pressures on the 30-40 psi range are commonplace as opposed to the 4 or 5 that a carb takes. You'd definitely need some sort of regulator unless efi is in your future as well.

With that said, your link is a nifty little gadget that I'll keep in the back of my mind should I find myself in that situation.

Yeah, I'm thinking about EFI. I checked the price to ship those little things and it isn't cheap.

Ford CFI systems circa '83-'84 used two pumps. A low-pressure in-tank pump and a high-pressure external pump. The in-tank pumps produced 6-8 psi, IIRC. A little bit high for a carb, but easily handled by a regulator.

The Aeromotive tank is another option.

I've been eyeing up the Spectra EFI tank for my future switch to fuel injection:

Amazon link:

The advantage of this one is the pump/sender assembly mounts under the car where the stock sender would be. So there's no wires/fuel lines/bulkhead fittings in the trunk.

Another option is FiTech has a pump that you mount in your factory tank. It does require a hole to be cut and fuel lines in the trunk though. I bought one but have not installed yet. I will say also FiTech has very good customer service or at least very prompt answering questions.
