    Nice kit and easy to do

    Thank you RiffRaff for including the O-ring and the rubber sleeve; mine was disintegrating as I removed the return line. Installed the gold spring and definitely notice that the truck is running smoother and quieter. I did sprout a small leak at my drain valve though so definitely keep in mind, increasing the pressure will certainly find any seals or O-rings that are not in good shape. Thankfully RiffRaff has the fuel bowl kit which is next up for me.

    Was super easy to install both O-rings were correct. My stock spring still had tension but was a little too short. Truck runs good. Can’t tell the difference but at least I know it’s in there.

    Seems to be a lot more responsive now that I used the gold spring from the kit.old spring from the kit. Other than that the engine is stock.

    Easy to install, black spring yielded me right at 65 psi post-fuel filter. Helped to quiet idle and injector clatter
