Does anyone know if these are legit? It's the only place I've seen them sold separately, without having to buy the whole module.

 

So mine just came in, and it's made in China for GM of Mexico. It does appear to be a legit AC Delco part, just not one that we can normally buy in the states. We will see how long it lasts...

 

5 months / 18k miles and it's toast! Not too bad for 50 bucks I guess, but lifting the bed is a PITA. I guess I'll go with a Delphi one this time.

 

i been working on a 2000 ecsb on and off for the past 2 weeks trying to figure out what was wrong with it.it would shut off but crank right back up.run ruff sometimes.couldn't never get it to do it when i had fuel pressure gauge hooked to it.this past week the owner of the truck calls me and tells me he put a cheap ebay acdelco pump in it and the truck didn't start running like that intil he did.im thinking thanks for telling me that know but anyways if you want to same some cash why don't you cut the bucket and put a walbro 255 in it.you will have a good pump and save alittle cash.its a win/win

 

I was just about to order one of these to build up a spare replacement fuel pump module for the 99. I was hoping this may actually be a quality direct replacement but I knew it was too good to be true. My buddy's fuel pump died on his 00 a while back and we ended up putting a 350 vortec pump in it. Money was tight for him and that was his cheapest option. It took a little work and didn't turn out too clean but it was mechanically sound.
