isnt the idle for 12v supposed to be around 700-800rpm?

:jump:It can be any rpm you want But yes to your question

mine does it also same rebuld smoke and chatter till warm i ran my grid heater to a montary push button toggle when i did my ford cummins conversion still does it if you dont run the grid heater

Mine did that, try draining the filter bowl, there could be water sitting in it.

i idle my truck near 1000 just what i like.

Yet another p pump not needing to be monkeyed with. It's AMAZING how often it turns out to not be the problem, when at first someone thinks it might be.

:jump:Yes the only time you should screw with a p pump is when you are trying to manipulate more power from it

REASON I WAS CONSIDERING THE P PUMP IS SIMPLY THE TRUCK DID NOT PERFORM THIS WAY BEFORE REBUILD WITH DIFFERENT COMPONENTS. JUST TIRED OF STINKING UP THE NEIGHBORHOOD EVERY MORNING.

Oh, I wasn't busting your balls about thinking it might be the pump. I was just making the point that it's incredibly rare that the pump actually turns out to be the problem.
