OK. I am working on a friends 88 bronco 2. I am inexperienced with this vehicle. The vehicle does not run, he said somebody put something in his gas. I disconected the line to the regulator and got no gas. I hotwired the fuel pump relay to get it to run constanly. I replaced his 2 fuel filters. If i disconect the line prior to the high pressure pump i get a steady trickle of gas. I disconect the line after the h.p. pump i get nothing. So i replaced the high pressure pump and i get VERY little gas still after the high pressure pump. If i disconect the line prior to the first filter i get a decent gush of fuel. i blew out the lines with air to make sure they are not clogged and they seem fine. :wtf: First off i have never seen a vehicle with two fuel pumps, but why isn't the high pressure pump blowing fuel 15 feet? any ideas are appreciated! please help advise

ok i replaced the inline pump. There is fuel getting to the pump. There is a VERY small amount getting to the fuel rail. When i turn the high pressure pump on i get absolutely nothing to the fuel rail. i am completely stumped.

ok. it got suggested to me to swap the in-tank pump to a '89 + so it is the high pressure pump. Then run a fuel line through a filter and directly to the fuel rail. My question is will the pump install into the gas tank. I can make the wiring match. does anyone see a problem with this?

sounds like a lot of unnecessary work to me. change the pump and call it good.
