I think hes asking about the final filter, one usually on the engine
, usually supplied by the engine
Not to be silly, but follow the fuel
line from the Racor
, it should go to the LP pump, then then a secondary filter, then the HP pump.
Order may be different, but if you follow the fuel
line, it has to go to a filter if you have one, maybe you don't?
Technically I don't see why you couldn't just have a Racor, but if I only had one, I'd make sure it's a 2 micron cartridge, assuming final filters are 2 micron, not sure. Point is to make sure you filter fuel to the engine manufacturers rating, or better
