Question about 1985 Ford F 250
I thought my O-rings were leaking on the fuel line because there was a puddle of fuel In my rear passenger side glow plug, but after replacing the O-rings, I realized that the fuel was gone. Anyway, I started my truck and realized that my O-rings weren't the problem, but the fuel was bubbling up from the inlet of my glow plug, please tell me this is an easy fix. I also want to know if this is the reason behind me having NO throttle response for about 5 seconds, and also my truck cuts off when I stop at a light, but starts right up like there isn't a problem. It all seems like the small fuel leak is causing my truck to lose prime and cut off. Please help

MY 2001 7.3 was leaking the same way. The dealer said the o'rings under the pedestal were leaking. I had the dealer replace the o'rings. By the time I got home, it was leaking again. Called the service department and told the manager,and they put on a new pedestal and o'rings. They only charged me half price for the pedestal and no labor. That did stop the leaks.

it sounds like your water seperator valve is leaking ..it is the valve on the back of the filter bowl .it is attached with 4 screws .and has a tube that drains on the right front of the motor..it can be replaced in a matter of minutes and costs about 50 dollars..

If the line leaking is plastic then it's not a brake line it's a fuel line. If the truck runs then it is most likely the return fuel line. If you can't get to it without dropping the tank then that's what you'll have to do, but you shouldn't need to remove it completely.
It is best to siphon out as much gas as possible. Before you removing the bolts take 2 pcs. of smooth fence wire or even 12ga. copper wire and make a cradle to support the tank, cut the wire at least 2 ft. longer than what it will take to go from the frame to the drive-shaft.
At a point about 1/3 in from each end of the tank lupe one end of the wire through holes in the frame and twist it a couple of times, then run it under the tank and around the drive shaft and twisting the ends a couple of turns.
After you get all the bolts out of the tank supports if you don't have room to repair the line you can loosen the wires around the drive-shaft and allow the tank to drop down some[this is why you need the wires 2 ft. longer]
After the repairs which will probably be replacing the rubber fuel hose that attaches the line to the tank,[I'd replace both of them] tighten the wires around the drive-shaft and replace the tank bolts. Remember to get all your bolts started before you tighten any,

Running Bio-Diesel should not be a problem, although BD is a great solvent that will dissolve petroleum desposits left behind by regular diesel. I suspect that the gaskets on the fuel drain valve are worn out and leaking fuel. Most of the time the whole valve is replaced, but I have seen only the two o-rings for sale on the internet. It is easier to repair by laying on your front side on a large pillow. If that does not work, come back to fixya and we will help you again.
