Once your up and runin a fuel heater is meaningless anyway, your fuel is gonna heat and doesn't matter if you want it to or not. I took my ride through some -60 weather last year comin across the mountains to with no factory pump hook ups. The heater did make me nervous but with additives the truck never flinched. But I have since put the factory filter back in place just for my peace of mind and now run both my Cummins spin on and the factory one.

 

with the fass hook up to hot water does it run better in cold weather

 

If you are up in weather that is always below -10 in the winter...then yes...i think it would help out. Other than that...use some good aditives and you should be good.

 

For those who are still interrested in running your fuel through your stock fuel filter housing, this is how i did it. I had to cut the top off of the stock fuel filter because it holds the gasket that seals the lid. Needed or not, it was simple to do and gives me piece of mind. As an added plus, it also gave me a spot to screw my Autometer fuel pressure gauge sensor into.

Ok ... here it is ...







It works great, I just wish I would have painted it red before re-useing it.

Oh well ..

 

I need to talk to someone about a FASS system. My truck stopped and we aren't getting fuel to the filter so we think the lift pump wen't out. Can you call me at 661-824-1948
