Re: 1r-0750 and 1r-0749

No difference inside other than length. Both same micro rating. These filters are meant to be used on the pressure side of the fuel system, not the suction side.

Sorry forgot to mention the only difference I believe is that the 1r0749 is about 4" longer and I'm going to be using it on an aftermarket setup. I just wanted to see if there was any difference in the inside.

Both are the same thread size and gasket size. The 1R0749 is longer so it may not fit in some applications.

1r-0750 and 1r-0749

So I'm using the 0750 right now but was given a case of 0749 filters.
I found specs but would like some input, are they interchangable ??? Thanks for any input!!
