I have a F350 diesel non- tubo with a fuel leak in back at top. replaced o ring at back injector and replaced all hose clamps but still bad runing leak. What next?


This engine has fuel lines that run to each injector from the injector pump. On the older Fords they touch each other in places. This constant vibration from the engine has caused a pin hole in one of your fuel lines to the injector. You will need to find the bad line. Can be hard as some of these are buried and hard to see. The replacement line will need to be purchased from Ford as each fuel line has to be a certain length and they are all high pressure lines. I have seen this many times in the older Fords.

Leaking fuel at injector


Leaking fuel at the injector is too risky,your going to have to replace the injector or injectors. They come out by the removale of the fuel rail.Here you need to be careful cause you can cause other injector to crack and make unnecessary expense.

Changed fuel lines on 1992 f 250 7.3 liter idi was old slow leak . now all m,y injectors are leaking right above big nut on the injectors looks as if its coming up from bottom of injectors ... real crazy...


sounds like you're gettting alot of fuel pressure now for sure,you may have to pull those injectors and replace the 'o' rings around them,they may have been bad all along and not enough fuel pressure to make them leak.when you replaced those fuel lines did you pull on the injector rack at all? if you did, the solution is simple,push the fuel rack back down to reseat those injector 'o' rings. that should solve it. otherwise your stuck pulling that fuel rack anyway so i would try pushing that rack down either way. it may seal the injectors back up. hope this helps and thank you for choosing fixya.com oncallmech

I have a gas leak under my hood. We replaced a part to try and stop the leak but it did not work. I dont know the name of the part. What else could it be?


your gonna have to find the leak source.. possibilties are fuel rail input and output seals.. fuel injector seals, fuel injector rails and fuel injectors. your gonna have to check them all and find the leak.

92 accord lx leaking on fuel rail


Dont replace just one O ring on the injectors. You need to replace all when you replace them. It sounds like you still have O ring leaks.
