T&T: Diesel Engine problem

[Mark Richter]

Jake,
The oil filter is not the problem; I've been using Wix filters on my Deere
4039 natural for years.  Perhaps in changing the oil filter you bumped or
moved some part of the fuel piping.

It sounds to me like an air leak in the fuel system.  Air leaks in, fuel
does not leak out, so it's very hard to find the problem.  The leak will be
in the area that is under vacuum, between the tank and the fuel lift pump on
the engine.  Try tightening every connection in this area, and the problem
may magically vanish.  When my Deere had only a few hundred hours on it, I
had a similar problem.  When I put my wrench on one of the engine-mounted
fuel pipes, it turned a full quarter-turn, and the problem went away.
Turning the nut required breaking the factory applied paint around it, so it
took a bit of torque.
