Fuel leak

**Cj Ford** · #1 (**permalink**) 10-19-2009, 08:15 PM

I noticed Im leaking fuel from my truck. It is running in the valley and off the back of the block. I changed the fuel filter and cap as it was time to anyway didn't stop the leak.. I was looking around for a leak with the truck running so the fuel lines would be pressurized, I cant seem to find anything but it is dripping while running if I shut it down it will stop leaking after a few mins

what are the common things to leak besides the filter cap on these trucks ? I need to start some where since the leak is not visible and I hate trucks that leak any fluids

My 99 F350 had a similar problem a few years ago. There are O-rings in the fuel filter drain valve in back of the fuel filter "bowl" that had to be replaced. I did not do this myself....a diesel shop did it for me..... 30 minutes of labor and around $5 in parts.

Good Luck!

alright, so I have a similar problem on my 95. It will not start without ether first start of the day. I know its fuel related because it was doing all this and I replaced the fuel pump and it solved the problem for several weeks and now its back to leaking again and not starting but only first start. could this be the same problem? also, is it possible to hook an air compressor to the Schroeder valve on the FPR with the truck off and listen for leaks?

Thanks!,

Brian

I'm having the same problem with mine right now. How much was the part? is it hard to change? Its driving me insane. There is deisel everywhere under my truck. Where is the line with the o-ring and what is the pet****? Not really familiar with what it looks like.

Alright, so believe it or not it was the crush washers that go between the banjo bolt and the banjo and the banjo and the fuel pump. It has to be retightened when the engine is at operating temperature to allow for expansion. finally starts now.
