GM EP381/Bosch 69225 install?

Has anyone ever installed the EP381 into the 97-05 Park Ave/2000-2005 Bonnie?

This is the old Syclone/Typhoon pump, that is used in a LOT of GM cars/trucks, and from what I gather, very well might be the same pump in the fuel pump modules. The EP381 replaced the lower flow EP379.

I did look at the 2000 Park Ave Ultra and the 99 GM Truck 454 pump and they physically are identical. I suspect they might be the same, the GM pump is said to support 300 hp, the 454 makes 290.

The EP381 is 50 GPH @ 55 psi. That I suspect is more than enough for a stock and lightly modded 3800 SC. It outflowed the TTA/GN pump.
