what kind of fuel issues are you having? Is it losing prime?

I know that i have a lot of problems with tk yanmars (in line injection pump) not starting in the cold. The fuel solenoid doesnt pull to full fuel position and sputters on and may start or crap out. Is there a solution for this yet, or am i just the only sucker out there??

Reefermadness, I haven't really experienced that problem yet. Usually if I have one with fuel issues, the problem is the following:

Inlet screen plugged
filter plugged
lines not tight (sucking air)
old POS rubber washers on transfer pump (sucking air)
Vent on tank bad
bad return line check valve (fuel bleeding back to tank)
bad transfer pump check valves (fuel bleeding back to tank)
fuel solenoid
junk in the bottom of tank
water in fuel
fuel gelling up (especially the new low sulfur fuel)
