300 SD fuel leak
Hello all,
I ran out of gas on my way to work this past tuesday (what a pain). I added more fuel, and used the hand primer pump under the hood and it started right up. I put about a half a tank in and drove the next two days. Yesterday, however, it happened again. I put about a gallon of fuel in, and went to use the hand pump, but it was loose. I screwed it back in, and tried to pump it but there was no pressure. I was unable to start it that night and got a ride home with a friend. At home, I saw a massive patch of what i believe is diesel fuel in my driveway. Could the primer pump be the source of the leak? Any suggestions as to how I may be able to patch it up? Thanks so much for the help! |

Possible, replace the primer pump and see what happens.

I forgot to mention that i have a non-functioning fuel gauge... I am not a complete idiot
When i used the pump the first time fuel would gush and leak a little with every pump, no theres nothing. I will try to loosen it and try again. thanks for the advice |

My gauge is flakey too. Fuel sending unit or something, caused me to run dry at least once. Now I just need to remember that the guage will not go below about 1/16 of a tank, that = E.

Carefully disassemble the sending unit (don't disturb the wires that come out of the can). Clean it thoroughly with brake cleaner spray. Reassemble and reinstall. Done. |

yeah, keeping a functioning fuel gauge is important. you may have lost a injector return line, or one of the many rubber hoses may have started leaking, the primer pump certainly can dump some fuel. most would notice the smell though. how dry is your engine compartment?

I assume your talking to the OP but I'll chime in anyways; my engine compartment is not exactly clean. My car marks it's territory. My eyes lead me to the turbo drain tube as the biggest culprit. Injectors into block seem good and clean though. Ever since I became aware of the 'overdrive' button beneath the accelerator, my blowby mess on the oil cap has doubled. Doh!
