I would like to add the fuel filter as try keep debris away from raptor pump(raptor 100) but I has research and not see what is correct way for me to get a part kit to do on my 2002 dodge ram 3500 cummins as 2wd dually. Also I had noticed the my raptor 100 would not increase te pressure even I did changed the fuel filter at stock canister that did increased from 15psi to 21 but now it went back to 14psi after few weeks driving. I had not get chance to pop the line off at raptor 100 to see at screen to see if plugging up? I had put my cummins into my garage and stay inside for few weeks as had not get time to look at it. Also do I should just upgrade for two filters with pump like air dog or fass?? I am plan to towing two Harley up to Wisconsin in October then December which over thousands miles to drive... I would like to see what is good way to do.

Could you explain the differences as well? I understand its a specification but clarify the difference between them both.

Absolute it 98.7% efficient at a certain micron rating, and nominal is anything less but generally 50% efficient.

Where can I get a "plumbing" that is good to use with diesel fluid? I got a fuel filter and fuel filter base but need plumbing to make it work but need know which is way to use material??

I used fuel injection hose from NAPA. It is high pressure and compatible with gas or diesel fuel. I used double hose clamps and barb tight fittings. Stay away from the quick disconnect fittings. They are a source of air suction leaks
