Spent $450 on a used injection pump and it saved my old Cummins

My 12-valve started running rough last month and I figured it was the lift pump again. But after chasing fuel pressure for two days, a buddy at the shop said check the injection pump timing. I found one off a wrecked truck for $450 and swapped it in over a weekend. It fired right up and smoothed out completely - no more hunting at idle. Has anyone else had luck with used pumps or do you always go reman?

That $450 gamble paid off better than most. I pulled a pump off a wrecked '01 Ram with 280k miles for my 12-valve last year. Paid $375 and it ran like a champ for 8 months before a seal started weeping. But hey, at $375 it's still cheaper than a rebuild kit and a weekend of cussing. My buddy swears by reman but he also buys new socks every month so take that for what it's worth. Old iron that was built in the 90s is tougher than anything you can buy off a shelf now.

PREACH. @the_kim you nailed it about things that were built right the first time. I scored a used P-pump off a running 1995 Ram with 180k on it for $200 cash out of a guy's barn. Bolted it on my 12-valve and it's been dry as a bone for two years now. That old Cummins iron was put together different, those pumps were built to last not to be cheap.

Picked up a used injection pump for my old Ford 7.3 a few years back for $350. Worked fine for two years until the seals finally gave out. Got me thinking how a lot of things in life are like that. People want everything new and shiny but sometimes the real value is in something that's already done its time. A used part that was built right in the first place can outlast a new cheap one any day.
