Yeah I do not think it is a problem on FB set up because of the large return line. On the stock fuel lines and two pumps I would stagger them like ZLFAB did. It would be nice to know if it is possible to run both pumps on stock lines. I would go that route for simplicity. Maybe somebody has the answear.

ZLFAB where on the frame rail did you mount the pump? Did you drill and tap or just used some self tapping screws?

 

It is possible to run both pumps at the same time. its a little noisey tho, you just have to change the whole tune. There is a couple 10mm wholes on the top of the rail behide the strut tower

 

Someone posted a picture on page 1 I beleive of where they mounted the pump, I
m putting mine in the same place.

Keep them both together.

 

First page bump.
