Dreaded Fuel Pump Failure (I think...)

[Pete]

Pretty sure this is it.
1996 2500 Chevy Suburban 7.4L and 1995 Corvette LT1 use same pump.
If you look up 1995 ZR-1 it shows the pumps AC Delco #19180770 X 2

As you know you will need 2 of them.

Or if you want to do the Bosch pumps: Bosch P/N 69225 these require making a relief slice in that plastic holder for the pump body, actually two cuts as these pumps are just a smidge fatter than the stock LT5 pumps. They work great though.

Sorry the rock auto site seems to have a thing against a direct link. Just log on, press button for the catalog, click "parts search", then fill in the P/N, Brand name of mfg, type of part, and click find.

Wasn't there someone selling a remake of the entire unit? I thought I heard grumblings of that last year...

That was the partsladi formally on Ebay. They no longer exist

and the pumps that came with that set up were not very good. One Brother had a failure in less than a month and I had a failure in less than 6k miles! We both bought the Bosch pumps. I have to give credit for the research to the other Brother as he found the swap with the Bosch pumps.

The only thing I am leery about is that when I bought mine two yrs ago they were $90.00 each....I don't know what to say about the price being lowered now. I don't even recall for 100% sure where the Bosch pumps that I bought back then were made....china? or Mexico? or IDK. Sorry Ron!

The 69225 is for same year suburban with 5.7L
The 69226 is for the 7.4L suburban and LT1 corvette.

If the 69225 fits better and plug is same maybe thats the way to go.

Zip Products sells the "remake" of the OE, LT5, pump assembly. Actually, it's more of an update rather than a remake as the Zip pump assmebly includes some modern technology in certain places.

I have a Zip pump assy in my 95. It's been there for about a year and about 5500 miles. It has worked flawlessly.

The PN is GT-406.

I stored my OE pump assy as a spare but...any of the OE pump assys still in service are a minium of 16 years old...beyond the pump's design life, I would think. Earlier in the thread someone pointed out that if the car has seen a lot of operation with low fuel levels, ie: below 1/4-tank, pump life can be shortened because they run hot. Also, if the car has spend any length of time more than a year not running, sometimes that causes a decrease in pump life due to gasoline turning to "varnish".

Thanks for the help...

I bought a pump and swapped it out this afternoon. She runs great! Man she has some torque for a N/A car.

The Bosch turbine pumps were made in Brazil, when I did the swap a while back. Here's the post where I described the procedure:
