Delphi fuel pumps
Has anyone noticed the quality of Delphi fuel pumps significantly reduced? I had two fail within 10k miles of install. The rear pump made it about 500 miles before failure, replaced with spectra and haven't had an issue since (about 8k miles). Front pump made it about 8500 miles and is now showing signs of failure, haven't replaced it yet. I know these have long been one of the go to pumps for our trucks. If in fact Delphi pumps are garbage now, are there any reliable options available?

I saw an old post (didn't note the date, sorry) that said Bosch made MotorCraft fuel pumps back in the day and that Bosch/Walbro is the same now, or at least whenever that post was made. Can anyone confirm if this is still true and maybe share a reliable source for them?
I may soon be in the market for replacement pumps also. Just wanted to add something for discussion and to subscribe to the thread.

Thanks for the responses. It's pretty discouraging to see the quality of parts getting so bad, really, really bad. I fear it may be the reason our trucks will finally be taken off the road, one by one. I've found that even Motorcraft sensors for these trucks are a total crap shoot anymore, it's no longer guaranteed that you will get a good Motorcraft part out of the box.

I use Ford pumps that I can get
Put one out of a T bird in the last truck I had thet needed one
You can usually just swap the new Ford pump into your fuel pump module assembly
I use 1992 Taurus recall fuel pumps a lot, they were 12 bucks during the recall IIRR, I still can get them but not 12 bucks

I was soo close to this. Now I just get proficient at doing it and make sure it has a lifetime warranty. Last one was changed in their parking lot.
