Hey guys. Happy new year. it's been a while.
I got some questions about a fuel leak. My new leak appears to be NOT filling up the valley like more common IP leaks.
I thought it was the rubber return lines, so after i replaced one and started it up, saw fuel coming from higher up near the coolant plumbing. You can see the one yellow transparent tube i replaced.
The leak is only on the driver's side, accumulating near glow plug #1/2 and thermostat sensor, and riding all the way down the trans cooler lines, dripping off there right under the trans on to the ground.
this is right behind driver's side alternator, top left corner of valve cover gasket. the stainless steel line that feeds IP i think is the culprit. does this stainless line ever fail? It seems to be pretty rusted. It leaks only while running, and is most definitely diesel fuel, not oil.
Side note: after watching some videos, here is the correct part for the IP fuel return lines if anyone happens to find this thread and needs that part number.
Alas, as I mentioned, this is not my issue. But- definitely a great thing to replace on an old truck anyway.
