Have any here successfully installed a Walbro 255LPH pump in the stock in-tank assembly for the EFI F-Series? If so, were there any fitment issues? Did you have any trouble with the fuel pressure regulator?

Here's what I'm looking at: New Walbro GSS340 Fuel Pump 255LPH High Pressure Ford Mazda Mercury 85 97 | eBay

I have a 1992 F-150 with the 4.9 L6 and dual tanks. The rear pump is out.

I'd installed a Walbro 255LPH pump in my '86 Mustang years ago and never had trouble with it. The installation was straight forward and I was able to reuse the stock in-tank assembly. The sound of the Walbro in the Mustang could best be described as low and threatening. I'd always get a kick out of flipping the key into the on position before ignition.

Thanks in advance.

 

It will not fit in the canister without major modifications.
