Have a C-7 cat with Alliance fuel filter need to carry a extra one used the one I had, is there a filter that I can get at NAPA auto to replace the alliance(2003 Mandalay 38A motor home)? #Alliance AB...
First a question: do you have ONLY that filter, or do you have a secondary fuel filter.
If only one, it IS the correct one (2 micron).
If you have two filters, it is NOT the correct filter for the PRIMARY filter. You want between a 10 and 30 micron primary followed by the two micron secondary.
