Hi all. I have been hunting for some information. My F150 has reached its time for rebirth, new engine, paint and the price much less than a new tk.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-comfficeffice" /><o></o>
I have also found that Ford no longer supplies some of the parts needed. I need some new o-rings for the fuel lines, supply line and return line where they attach to the fuel rail. Both lines do not look to be the same size. There are 2 o-rings on each line. Does anyone know what size the o-rings are or where I can get them from? The o-rings are not your normal o-rings but must resist the fuel and pressure like the VITON o-rings. <o></o>

Have you tried LMC? maybe Jeff's Bronco Graveyard stock them also.

 

Use a pick to pull one out. Take it to a good auto parts store or industrial supply house, either of those can set you up with a proper o-ring.

If you're looking for the o'rings where the nylon hoses attach
to the fuel rail, scroll down to Dorman 800-013

May find them in the HELP section at the auto part store.
The fuel lines are 3/8 and 5/16.

 

Thanks! I have just ordered them and they will be here this afternoon. The lines are steel on the trucks but are not very long, they revert back to rubber with the nylon fittings and then use push lock clips. These o-rings look to be what I need, I will see soon. "Thanks again" Big Red XLT
