1995 K3500 Fuel Pump/Sending unit

[Madwerx]

Hello, having trouble finding information on what fuel pump to buy for my 1995 K3500 7.4L, I believe it's the 34 gallon tank. Trying to stay with OEM.

Looking at this OEM Delphi hp10025: https://www.napaonline.com/en/p/DFPHP10025

This delphi one lists cab and chassis w/ 22 gallon tank.
"Left; Cab & Chassis; with 22 Gallon Tank; with Code # VSE,VPB,VRE,VFN,VRP;"

looks the same, but Is there different lengths used?

Amazon review here is throwing me off, Randy says they're different height: https://www.amazon.com/ask/questions/TxFCVP4Q75O3YS/?

Any help appreciated!!! Thanks!

I think I figured it out studying the tanks on rock auto, the HP10025 is listed for the 22 gallon tank which the dimensions say is a 14" height, similar to the 25 and 34 gallon tanks height at 14.13" and 14.25".

I don't think it would work for the 31 gallon tank which dimensions are listed at a 12.75" tank height, but it might?

I did order the Delphi sending unit/pump, I can measure it when it arrives and post back to help other searching in the future.

The Delphi HP10025 or ACdelco #19111394 is for the 22, 25 and 34 gallon tanks.

The Delphi HP10022 is for the 31 gallon tank.

Note: I believe the later models (1996 and up) used quick connects for the fuel lines where the earlier models like my 1995 used bolt on fuel lines.
