*I would tend to agree with Chris on this one. The issue pretty much has to be in the delivery side, as the return side is open to atmosphere already.Chrisjs wrote:
If I understand correctly, your engine "loses prime" while standing for a short period of a few weeks (or less?) while not running.
We have a similar 6BTA5-9 (1999) with 2,500 hrs. and have never had any need to re-prime the fuel line even after 7 months of winter storage.
I would have to concur with others that there must be an air leak somewhere on the delivery side. The only other question I would ask (and am unable to answer)
is whether there could be some pressure in the return fuel line (closed/clogged valve, kinked line etc) that might somehow present as a similar problem.
As with Doc, would sure like to know the answer--- it could be my problem next!!
