PC78 fuel pump

[NWH]

Can the fuel lift
pump on a 2008 Komatsu PC78US-6 excavator be replaced without having to buy the entire injection pump assembly ?

Yes.. It has a P# on it.. DO NOT SCRAPE IT.. get some paint/gasket remover in a spray can at the parts store or walmart.. spray it on, wait 30 seconds & wipe it off..
OR u could just remove it & have it rebuilt..& will be back in your hands quicker than ordering a new 1..
U can get the #'s off the main inj. pump & the fuel shop can find the # of the supply pump THAT WAY.

like just the hand pumping element???
since you in there clean the fuel screen inside the banjo fitton on the line from the tank to the lift pump block.
pull the banjo fitting out and the screen will unscrew from the inside of the bolt.
DK152200-5420 is the p/n for the hand primer.

I think the part I am referring to is also called the feed pump

Feed pump, lift pump, supply pump.. ALL the SAME.. depends on what part of the country ur from.
Just tell'm its the little pump thats bolted to the side of the main inj. pump..
