fuel pump ....

[cmc76]

Im thinking I already have the answer to this, but figured I would see if there are any ideas im missing.
Ive got about 158k on what I believe is an original fuel pump. Sunday afternoon, I had about a quarter tank. started and died, then would crank but not fire. I was out running errands and couldn't do too much investigation, so I climbed under and smacked the gas tank with a snow brush. climbed back in and it fired right up.

Yup that's where I'd put my money.

Mine does the same exact thing at around 1\4 tank. Just had an issue where I was going down the road and the engine sputtered and just cut out on me. I let it sit, primed the fuel pump a few times and it started right up again it did this multiple times.
I'm having to do the fuel pump on mine as well. It seems like the fuel pumps in these like to go out right around 150,000 or so my moms avalanche did the exact same thing and she had to have hers replaced as well.

Have you rented a fuel pressure gauge and taken readings?

I have not done so. I am taking it somewhere and they're taking a look at it

I suggest a OEM fuel pump. I had an aftermarket one and I would only burn 16-18gal and it said it was empty. I guess more or less its a float issue but I spent a lot more time at gas stations. I now have an OEM fuel pump and now I am back to pumping 20-22gal when gauge reads empty.

i was looking on amazon, they have a Delco for about $160 the other options ive seen were napa, autozone etc and they were all over $300.
Is there any reason to be paying nearly double?
