Works like a charm

Dusty Landrum (Vallejo, CA, US)
2G GSX Fuel Hanger Fitting

Used this on my 99 Eclipse GSX for an upgraded 400lps walbro pump upgrade. I used this fitting for the fuel return line. Obviously requires modification of the fuel hanger for BOTH the fuel feed AND return. Can also cause modification to the fuel feed hanger line coming from the driver's side second "pump". Great product and sealed tight.

Worked like a charm!

This fitting is pretty much a must if you’re going AN direct from the pump on a 2g awd dsm. The low profile really helps to ensure it’ll fit without hitting the seat cover.
