Fuel pump issues
Anyone ever expearance loss of power, studdering while trying to accelerate, backfiring on hot 110* plus days?
I have a feeling its my fuel pump on the basis that only happens on very hot days and i notice the noise your typical fuel pumps make is MUCH louder when i loose power.... usually sofar i wait an hour or two and im good to go. I have a hard time repelcateing the problem and ofcourse as murphy has it not when im carrying my fuel pressure gauge amd sockets to get the intake off.

never mind, was able to limp home and get my fuel pressure gauge installed before everything cooled down and able to replicate the problem. the diagnosis is a bad fuel pump, popped the 2 bench seats out, pulled the seat brackets out, folded the carpet back and cut an access hole into the floor. in 3 hours from start to finish had pump replaced and interior put back.

also i expect the aftermarket pump to fail again at somepoint, now it will be a hour job to replace it rather than multiple hours.

in my opinion i can pop 2 bench seats out, zipp 8 seat bracks off the floor with my air gun, and fold the rug back faster than me having to drain the tank, put the whole vehicle up on blocks so you can get the tank down and out, etc.

could of cut the access hole roughly 3" over one direction more than i did but oh well its workable, and the system for re ataching the plate could be better but what ever i think it will work fine.

I have cut a hole in the floor in all 4 of my vans,at one time or another. Trying to drain fuel and support the tank is a total PITA. Not only that, you have to disconnect the lines while reaching over the tank.My experience with aftermarket pumps is that they will fail at the least oportune time.I now pay the premium price and only use Ford pumps.You have the older style with the lock ring. The newer ones use 6 or 8 screws to hold the pump in.With the floor cut,I can change a pump in less than 1/2 hour. rick
