just a stupid question...

But i have to ask.... Is it possible that the lift pump gasket has developed a leak? or is my fuel heater the culprit... i have diesel fuel stains on that location of the block..

Truck is gettin a bit stubborn to start after it sits for more than a day or two, or more than 12-15 hours.. Starts up after two or three cranks, with some throttle, idles rough for a few seconds, and evens out with some throttle, and will start off easily the rest of the day....

I have checked return lines, OFV is good, all lines are tight.. i know its gettin air somewhere... which is why i ask the above question.. thanks guys!

 

Quite well could be the fuel heater. Get rid of it, you won't ever need it down there.

 

thanks pat!

 

Leaking return hose can appear to be coming from most anywhere below it.
