Hello,

I have an '89 F-250 with a rusted fuel line between the fuel pump and the fuel selector for the dual tanks. This line appears to be 7-8 feet in length and crosses from the left side to the right side at the engine crossmember. It appears to be routed fairly close to the right side exhaust manifold.

The parts man at the local Ford dealer said I could run rubber fuel line for this entire distance. I have concerns about the proximity to the exhaust manifold damaging rubber hose. I also read in the owner's manual that diesel fuel should not be stored in galvanized steel tanks. Does the steel tubing sold at the parts store have galvanizing on the inside? Can soft copper tubing be used, or does diesel fuel have some adverse effect on it also?

Thanks for the help.

 

Go ruber fuel line & never look back, Tie it tight across the frame & everywhere it loops out,
I did complete fuel system when I got my '92 last year right from the rear tank up. A bit of a job but rust never sleeps under there.You will need the plastic adapters to start at the pick-ups of each tank.I even did the tranny lines in rubber & have been leak free since.
My buddy did this 4yrs back on his '89 still dry & happy today, thats where I got the notion.

 

loudwayne,

Rubber it will be. Thanks for the input.

 

if you want really long term go plastic its hard but i used rubber and it wears over time.

 

Don't use copper.
The vibration can cause it to work-harden and crack.

 

I have to run lines from the tanks to the change over valve, Could i just use rubber?

 

You can use steel brake line or rubber, if you use rubber, make sure it will hold up to diesel.

 

i used rubber from the tanks to the cross over valve and plastic inside the tank for the pick up. You should use plastic it last longer but harder to put on i used rubber it its all good so far.
