Fuel Pressure Regulator install

[mookie980g]

hey just thought id post this for anybody looking to replace their FPRV just a few pick and tips. well first off its not all that bad just alot of disconnecting of sensors, the hardest part to me was trying to get the last bolt on the bottom of the FPR i had to rig a allen key because my torx socket was too big to fit in there but in the end it was worth it i have a extremely smooth idle, 1-2 mpg difference and the throttle is definitely more responsive. my fpr was bad from the day i bought my truck so this was like a night and day difference. here are some pics in progress.
