I need help fuel pump

[zambizzi]

do I need 2 fuel pumps for a late model m20b25?
also can I reuse a m40 fuel pump?

What year is your car?

Looks like M40s before March '88 used a 2 pump system, after Mar '88 they used a single high pressure pump like the late model US M20B25.

The fuel pump in your car is different from the one found in cars with the m20b25. I spent $400 to find out.

It is a different pump, but I know an m20 will run with a stock 91 318is pump setup.

I've been running the TRE pump for 3 yrs. Works well, they are a good company.

The single in-tank high pressure pump for a late production 318is is not the same as the pump for a 325is/i/ic built from 9/87 on.
