The pump as originally released for MY03
medium duty use (for elevations up to 12,000 ft) was P/N 15751278.

Later that year we rolled in the version with drain holes in the motor
housing....P/N 15198448

This what I had stored.....

Johnny,

The part number for the pump is GM Part #94669091.
Your local dealer can get one, or you can get it from P & G Chevy. Don't wait 'cause the price is going up slowly. This part was an exact fit on my '91, nothing to change or modify. WVZR1 mentioned in a post that there is a connector available to adapt this pump to a '90. You can also probably make one pretty easy.

Hope that helps.
