Bart, wanted to give you a heads up. Don't know if this will help your gas mileage issue, but I was changing my FPR out today due to the VX taking a few more cranks than usual to get started, and I noticed that the rubber tube connected to the FPR was cracked and wasn't getting a good seal. I haven't started the VX after it has sat for a while to see if my slow start issue has been taken care of, but I'm wondering if my FPR was just fine and I just needed to trim the tube down so it could get a better seal.
