M35A3 Fuel Leak

[glcaines]

I made a ~70 mile trip in my M35A3 today, dropping off a load at the Transfer Station and picking up a load of plywood at Mountain Building Supply n Blairsville. After arriving back home and letting the engine idle to cool the turbo, I noticed that I had a small stream of diesel fuel pouring out from under the engine. It was difficult to see where it was coming from, but I finally found the source. The large ~1/2-inch air line going back to the air dryer was rubbing on the fuel line that runs between the filter assembly and the IP. A small hole was rubbed in the fuel line. Unfortunately, fuel was spraying all over everything making it difficult to determine the source. Should be a simple fix since the fuel line is relatively short and fairly easy to get to. Other A3 owners should take note, because in my opinion this is a design flaw. The fuel and air lines rub against each other due to poor routing of the lines. Other A3 owners should look at their trucks to see if they may have a future problem.

This should be a regular check for anyone who ones a Deuce or any vehicle. You should regularly check all lines and hoses for rubbing and chaffing and properly secure them. During our regular scheduled maintenance on all our buses one of the things on the check-off list is to check all lines and hoses for rubbing and chaffing. Clamps break off and lines become loose. They can cause some severe problems if left unchecked.
