💪 Enhanced Performance: P7100 Injection Pump 3K/4K Governor Springs for Cummins '94-98 12V 5.9L - Perfect Compatibility! Review

didn't work on first install because my fuel pump wasn't delivering enough fuel. had to get a 0 tank plate and it worked great.

Pants large fit increases. Can cause high idle, I had to make several attempts to loosen the lock nut to equalize the idle and meet specs.

They worked as advertised and do not dump fuel up to 3500rpm on a stock engine. I only cranked it up to 3500 once to get the revs up. installed, but for a DIYer they work great. I also used all 4 springs and it greatly improved high power performance.

complete set that works well. P7100 pumps respond very well to simple mods like governor springs and fuel plates. This ESC Spring Kit gives you the option to go from stock to a safe 3k, or go all out and go all the way to the 4k limit as you make more mods to support. this level of sales. When installing 4k limiter springs, 60/lb or higher valve springs should be used to avoid valve shifting and possible engine damage.
