If the hanger is the same as the GN, it will work but will be a tight fit. I used a couple of hose clamps to secure the pump to the hanger. Make sure you change out the 15 amp fuel pump fuse for a higher rated one.
I removed the "Saginaw" restrictor at the hanger before I could get the fp to adjust downward. However, soon as weather permits I'm going to hookup the return to the vent line just to be on the safe side.
I have a TR floating around with a DW 400 in. It uses the Vent line for a return, and I used a new sending unit. I had The Wrath run a secondary power and ground through the sending hat. Richard Clark stated it pulled less amps than the Walbro 450 so I feel safe. So far so good on E85 from day one.
