1988 F250? 4WD Fuel System
Type: 8 Cylinder 5.8/351 Gas


I have fuel leaking, driver side, looks like it's the pump nested in the frame.
Can anyone lead me to a diagram that shows routing of fuel system, from engine to tanks?
This is a farm truck. The dash gauges need to be redone (future project), rear tank, etc... but it is a beast and can pull...
I'm getting ready today to crawl underneath and see if I can remove the pump I think is leaking... any help would be appreciated, i.e., best place to get parts... manuals... etc.

Fuel pump or Dual Function Reservoir is leaking?

Another closer view of the reservoir:

 

Yup, that's it. I found it after my initial post. The fuel was pouring out from around the top of the cup. I gave it about a half turn and it's not leaking any more... but I'm sure the o-ring is going, going, almost gone.
I went to Discount Auto but they could not find the ring or filter (or even a picture of the 'Dual Function Reservoir'). All I found in a Haynes manual was reference to a 3-port fuel tank switch, no pictures.
So, anyway, where can I find part numbers for the o-ring and filter?

Thanks for taking the time to post the pic's.

 

A question about the 4 hoses coming out of the back - are those a feed and return for each of the tanks? My rear tank is completely disconnected and an upcoming project is to get everything back to original.

 

From Steve83: For a replacement O-ring for the cup, buy a NAPA 3268, Fram CG3862, or equivalent filter.

Yes

 

And for the bonus round....which is which? My system is disconnected and I'd like to get it back to stock. Right now I have a single feed coming from the front pump to a carburetor (was originally EFI with a different engine)

 

From Steve83:

 

Wow, hat's off to you! I'd buy you a beer, but I try not to go any farther north than I have to, so here are a few e-beers instead.

 

LOL!

yes, I do live north of US36 which is our version of the Mason - Dixon line.

Thanks for the frosty ones
