fuel pumps
Has anyone successfully changed the fuel system to one that works !!
I don,t like having to guess how much fuel I have and how long the pumps will run and which tank will work today!!
Any help is appreciated.

I fill the back tank, but always run off front tank. Rear fills front!!
But, as front tank is getting empty, the gauge will bounce from its normally always on full reading to 1/4 tank. At this point, I switch to rear tank, which sometimes reads full , sometimes empty, sometimes in between. It runs poorly off this tank.
I then fill up rear again, but never needs more than 1/2 tank to fill!!
If I fill front tank, I get gas backing into rear tank.
I bought it used and it has done this to some degree since I got it.
It is an 88f150, 4.9.
As for ford not having problems with fuel system , a search of sites turns up loads of isues which is why I posted this question.I just would like to not worry about the gas . By the way, my 85 f150 gauge never read right either.
Thanks again for replies.

I have a 90 f150 5.8. Ran great gages fine, one day I found front tank gage will not display and started cross fueling to rear tank. So, I ran the truck on rear tank only till I could repair.
Research led to a tsb that said both pumps needed to be replaced to prevent cross fueling.
Before I could fix the truck it wouldn't start on either tank. I had to leave town unexpectedly so had towed to repair shop and they replaced "two BAD pumps". Picked up truck and ran great/gages fine. shut off truck then would not restart. Mechanic replaced fuel relay by air box but now:
will not power rear tank but rear tank displays the amount of fuel in rear tank.
will only run on front tank but will not display at all on fuel gage.
If I switch from front to rear while running it immediatley dies.

I think that this would be it? I dont know...my truck is a 90, so would the recalls be in 90? or would Ford have done some recalls on it in latter years....such as 91 on up? Thx.....

Here's the other thread that talks about the fuel cross over recall. Don't know if you ever had this done or not.

yea i drive a 90 f150 with a 300 in it and i just recently had to replace both pumps, i was havin some what of a similar problem. i changed the pumps and the selector switch( with a little riggin of course) but now both tanks read and work properly. if you do change the pumps i recommend liftin the bed, its easier than droppin the tanks i think anyways let me know what happens

I am thinking about pulling everything out and putting inline fuel pump back by tank. I probably will go with one tank only if I can get gauge working somehow with an aftermarket item or something.
