Investigation reveals that Volvo diesel fuel filter is about half empty after motor is idle for 3 days or more. It appears that fuel is leaking back into fuel tank. Motor will start after fuel is regenerated (about 10 seconds of cranking). Once started eng exaust is very smokey. What allows fuel to draing backwards into fuel tank ? Is there a possibillity that fuel is leaking through the return line ?? Maybe fuel injectors leaking ? -- What procedures should I use to isolate the problem ?
Eng has about 2500 hrs -- Fuel injector overhauled about 300 hrs back -- Injectors reconditioned about 700 hrs back -- new fuel pump 50 hrs back --
all fittings have been re-tightened -- compression is good.
Does anyone have a suggestion of how to resolve this problem.
