I have a buddy that is going to be upgrading his fuel system soon and he asked me if I would want his old 255 LPH walbro. Have any of you guys ever put 2 in tank pumps in a fox body? When I did a search, I found some guys with newer mustangs have done this but couldn’t find any info in the Fox 5.0 section. I was thinking that I could run both pumps to a ½” (10 AN) line then split to two 3/8” (6AN) at my aftermarket rails. Then use the old 5/16 feed line as my return.

I think the 03/04 Cobras run multiple pumps. Either 2 or 3 I don't remember.

I have read about that but, I was wondering if anyone had done that with a fox tank and fuel pump hanger. Thanks for the reply though.

Not intank but I've done it with 2 external 255lph pumps. Im sure I could fab something but getting them into the tank would take some fabbing

This might seem like a stupid question but, was the 2 pumps you used just externally mounted in tank pumps?

Two inline style Walbro pumps ....can use a aftermarket pickup or braze an fittings on the stock one so u can use braided or pushloc hose.

Ok, thanks for clearing that up. I didn't think you could externally mount in tank pumps. If I get the pump from my buddy, I will try to post up the results of riggin it up.
