GM part number for TPI fuel pump

What is the part number for the GM fuel pump? Are all years the same pump?

Dont bother with a GM fuel pump... do a search here for Walbro pumps and get one. I just put mine in Saturday, when my AC-Delco couldnt keep the pressure up. I had just replaced it less than 2 years ago too.

Here's some Delco #s for reference. I've gathered it from various places and cannot guarantee it's accuracy.

305 TPI, EP-241 - 24 GPH @ 50 psi
350 TPI, EP-242 - 28 GPH @ 50 psi
LT1, EP-271 - 33 GPH @ 51 psi
Syclone, EP-381 - 41 GPH @ 51 psi

I replaced my failing stock pump with the EP-381. It was a direct bolt-in. If I did it again today I'd probably go Walbro.
