does anyone know what size fittings i would need to replace the return line.I want to change it all with braided stainless hose i just need to know what size goes into the block and pump thanks

 

Are you talking about replacing the rubber lines with stainless? Any particular reason? You could probably buy a sick lift pump for that same price that youll have in stainless. LoL
Im running a AirDog 150 and have no fueling issues at all with 1/2" rubber.

 

You don't need the S.S. line there is no high pressure return or supply lines on these trucks.But if you want to change them to S.S. lines #10 S.S. line is big enough.

 

no i dnt hp lines that damn return line the one that tees off and goes back to tank it goes behind the block and to the pump i just wana change it its all rusty and i dnt want it to leak and i already have a airdog and i need the fitting sizes cause i seriously doubt there npt
