I’m doing a refresh and would like for someone to point me into the right direction when it comes to fuel pumps. Thanks!

Since the car has two, factory or pier burg, Bosch would make the main pump but I don’t know if they make the pre pump
Thanks! Should I be searching for an In-Tank or In-Line? From what I’ve found, I believe I need an In-Tank for my car.

I bought my in tank pump unit from Auto zone about 3 yrs ago and no problem so far. About $175.
Sean2005,
The in-tank is the pre-pump or some call it the primer pump.
Do both pumps

Do both pumps
Do both pumps prime, no just the in-tank.
In-tank about 4psi, the main upwards of 43psi.

Just to through in a few cents worth: My 81 Euro, with Motronic 1.o only runs a main pump. Real oem shows it with an in tank pump, but I know mine never had been apart and is totally original. Go figger
