Then you can use the tank you have. These units were fed from the low pressure in-tank units that fed carbs. VW didnt want to invest in a new stamping, so they cam up with this external pump/sump The unit is complete, pump, filter, plumbing, plastic reservoir to prevent stalling. The pump is a bosch 4 Bar unit. Good for about 400-450Hp (then it runs out of flow and pressure starts to drop)
If I can find the one in my garage that I pulled off a parts car Fox I had and kept for the Opel project(its in a box, inside another box in a pile of boxes) I will post a pic.

I only had to add a return line to the mustang tank I have mounted under the bed. | | | | | Joined: Dec 2007 Posts: 180 Wrench Fetcher | | Wrench Fetcher Joined: Dec 2007 Posts: 180 | that is what I have been thinking, I have worked on many mustangs and they have been setup like that for years. (external pump) with a pickup in the tank. they seldom have fuel pump problems. I have access to a blazer tank cheap this should work. | | | | | Joined: Dec 2007 Posts: 180 Wrench Fetcher | | Wrench Fetcher Joined: Dec 2007 Posts: 180 | Look at the late 80's early 90's Suburban/Blazer tanks they used TPI & EFI in them...joe what are the dimensions on those? will they fit? | | |
