Hi all,

I have a 1990 Ford F250 diesel, ext cab, 4x4, e4od, and now that it is summertime, I am trying to get some things fixed that have been on my "to do" list for a while.

My front fuel tank has 2 problems . . .

First and foremost, the sending gauge to the front tank does not register when I switch it over. It just drops straight to E. This just happened recently, but before it stopped working, I would always feel like I was running out of fuel a little under a quarter of a tank.

It seems like the 2 main issues here are the sending unit and a cracked or broken fuel pickup.

Here are my questions . . .

How difficult is it to drop the front fuel tank on this truck?

How difficult is it to replace that fuel pickup? What sort of material is it?

Is there any way that I can check/test the sending unit instead of just buying a new one? Maybe it's just a ground connection or something, but I don't know where to check.

Any help would be greatly appreciated.

Thank you all so much!

Joe
