5.0 Fuel Pump and Regulator

[57Explorer]

I have continued to search to no avail. Sorry if it is obvoius.

I have a '98 5.0 Explorer that I am putting in bigger stuff in. What size is the pump in the '98 5.0 Explorer? It looks by my calculations that a 190lph pump will fit my needs (NA 331, 30lb injectors, custom cam, AFR185's, custom headers, RPM II intake, estimated HP ~350). If the Explorer does not have a 190lph pump, can I use a Walbro pump designed for a Mustang?

I need to add an adjustable fuel pressure regulator. Can I use one designed for a 94-95 Mustang 5.0?

Stock Explorer fuel pump is a very low rating. 190 is a good choice; an aftermarket mustang product will fit quite well. You have to drop your fuel tank for access.

I had problems with size on aftermarket adjustable FPR's and used a mustang adjustable (size about like stock) and worked well also.

What FPR did you use? What was the size problem?
