2022-12-29 FASS Fuel System

2002 5.9L Cummins are known to have weak lift pumps (LP). The LP provides inlet pressure to the High Pressure Pump (HPP). Under heavy loads the LP can't keep up, pressure and flow drops, the HPP galls and you're out 5k bucks.

FASS system fixes all that and more. I chose this one.

Unfortunately, Top Tier Suspensions were sloooow to ship and I had to wait, not knowing only 30 days are allowed to register warranty. Fortunately it was registered today and I called FASS 1-866-769-3747, left voicemail.
