Walboro 405's

[DeMartino17]

Can you run the 405's on a stock 04 cobra fuel system? Wasn't sure if they'd work with the hat without modification or anything else. Pump gas car, no race/E85 fuel.
I originally planned to do injectors and just a BAP but the pumps are a good deal.

I have put a single 405 on a 2v hat with an upgraded fpdm and upgraded wiring with success. Two 405's took a ton of work to try and make fit and in the end are too much for the pcm and dual fpdms to handle in returnless though, they were very hard to tune and pressure was all over the place. I would look into dual DW300M pumps for something that will fit easy and work well in returnless.
