[QUOTE="TRBO VNM, post: 14945766, member: 14678"] Sounds to me like the pprv was removed when doing the ford gt pump install. Which is common. That pprv is the check valve in the tank and causes hesitation issues. So you need to cycle the key a few times before you start it so it can build pressure in the lines. Dropping pressure fast after shut down sounds normal with no check valve. There are some things you can adjust in the tune for hard starts when the car is hot [/QUOTE]
