'84 6.9 No Start

Hey All!
My '84 F250 has had a lot of trouble starting lately. If it sits for more than 2-3 days it will act like it is not getting any fuel. I'm guessing i have an air leak somewhere that is letting the fuel drain back. My question is wether or not I can install some type of check valve or shut-off lever so the fuel will not drain back. If so, where should I install it? Return line? after the filter? Any input on this will be helpful
Thanks
Kevin

Schmittys diesel,
Welcome to FTE and the IDI diesel forum.

Most times this can be fixed by changine the return lines and O rings under the return tees.

Yeah, I recently replaced the o-rings on the return trees..which didn't seem to help one bit. Is it very difficult to replace all the return lines?

Just replace all the retun lines on the engine.
When I do mine I remove one side, change the O rings, and then rebuild the return tee set for that side. After it is reinstalled I repeat for the other side.

No can do a check valve....... You state you only did the orings unfortunately the caps distort too, get a kit. There are numerous other places on the filter header too.
