[6600DURAMAX]

The fittings I used where no name from EBAY imagine that I tried to save $20 and they leak! I am going to try to use some more tread sealant on the npt one and maybe jsut get another straight fitting if it continues. I am using the black fiber wrapped hose and it is for a gasoline engine.

I will remember to buy name brand ones next time that is for sure. I do have the koul tool but it is at the other house 150 miles away. I do however like the black fiber wrapped hose instead of the stainlesss hose, it seamed to assemble easier.
