A few weeks back my mighty GU was stalling [nearly] when stopped whislt cold .
After that it ran fine started well no problems at all.
So I warmed it up longer thinking fuel was leaking back some how, then it struggled
to start but once started it was fine. Then I could smell diesel and looking under the GU
there was a pool of fuel. Had a mechanic friend have a look and found the return
fuel line was perished and leaking fuel under pressure. $8.75 later for some 6mm fuel line from
Super Cheap and all was well again. The mighty GU is better than ever. Gotta love a happy ending
