Electric Fuel pump recommendations.

[chmhasy]

I just went through two mechanical fuel pumps. looking for a recommendation for an in-tank or out of tank electric fuel pump. In-tank would make it easier for me to just drop it in and I would just have to reroute the fuel lines where the Mechanical pump is now.
MKIV Roadster, Quickfuel Carbureted 351 Windsor
Ron Francis wiring harness. all components are there ready to plug in.
Single fuel line no return. I may need to get a fuel regulator.

Thanks

Where do you have your fuel filter mounted?

It's mechanical, so it is on the lower left front side of the motor

That looks like a good option.

Thanks

Before or after the pump?

I've been able to find good MK4 compatible components for my build at Pro-M Racing (www.promracing.com). I'm going with an EFI set-up so not sure that what I've found there would be helpful to you. Also...I'm a newbie, too, so take any suggestion from me as what they are...an attempt to be helpful from someone who knows just enough to be dangerous. :)

I am sorry, I read that wrong, the fuel filter is just after the tank in the rear of the car

This is most likely why you've had mechanical fuel pump failures. You shouldn't have a filter on the suction side of a pump. The resistance from the filter restricts the pump, causing early failure. May not mater if you've decided on an electric pump, but move the filter to the pressure side of the pump, not the suction side.

If you decide on an electric pump use an in tank. My number one regret by a MILE was using an external fuel pump. I mounted it under the passenger seat pan and it's pretty loud. I find it weird that in an open air car with a loud open exhaust the fuel pump drone bothers me but it really does. I will without question be converting my setup to an in tank this winter.

Thank you, I will do that.

I have a NIB 265 LPH in tank pump in the parts for sale area if interested.

Hi davamor. Like you, I'm a raw newbie but have benefited hugely from this forum. Someone (GoDad?) recommended a ProM in-tank fuel pump. This is what I went with: https://www.promracing.com/high-flow-fuel-pump-hanger-for-1986-1997-mustangs.html
The fact that it returns fuel at the bottom of the tank and thus avoids cavitation is what sold me (plus the 3/8" line fittings).
