I had to order a new few filter housing from stateside. I installed it and removed the primeloc today. I have a low power bad mileage problem too so I installed new IAT MAP and Coolant temperature sensor. Which is not what they call them at the dealership. I have a new lift pump to get all the fuel there. My new housing gives me great pressure. With the primeloc it went negative pressure in about 4 seconds now its 9 psi wot all the way to 110mph. If all the sensors dont help im gonna get a tps(quoted $406 at the stealer) and crankshaft sensor. Fix it till its broke(or i am).
