Bosch fuel pumps. You can get them anywhere, also mkenzies and kartek

They are the high pressure pumps used on BMW, Mercedes, and Porshe. Usually $300-$500 ea.

Here is a link I found that tells you everything you want to know about bosch pumps. I think most / alot of people use the 0 580 254 044 I have heard it called the super 44.

thanks for the info. i like how they are threaded in & out. many are not. makes a much cleaner plumbing install.

We have used these for years with ZERO problems. They are very good pumps to use. There is one with a built in check valve, that is the one we like to use...

edit...
We also use the bosch filters as well. We use a pre and a post filter...

If you are buying these make sure it is actually a Bosch, and not a chinese made one. Big difference in quality.

yes there is a difference buy bosh not boshching . also on the inlet they make a y an fitting . the t can actually create problems .with cavitation

[fusionoffroad]

also though a clean install the pump can seize being tightened in the center . you should lightly clamp the pumps on both ends . I am not picking this install apart but I have went through every problem in the world with fuel delivery systems . the t in the pickup line gave me a starvation problem at 1/4 tank .when I had the center of the pumps clamped we ruined the internal impellers.
