Installed RiffRaff Fuel mod?
I just installed the Riffraff Regulated Fuel return line mod and the instructions say that if the spring is not centered then you will have to much fuel pressure. There is no way to install the system and know for sure if the spring is centered. You are in a tight area holding the Frx, the bolts, the spring/plunger and trying to align all the components. Anyway, the install went just fine, I had no problem getting the new fuel block installed and there are no leaks and the truck running fine.
My questions is: How do I know if my fuel pressure is to High? Will the truck run funny? Will the check engine light come on?
I don't have a fuel pressure gauge as of yet.

There isn't a positive way without having a fuel pressure gauge, but there will be a lot of resistance when you install the fuel block if the spring is crossed.

Thanks Clay, no resistance on install. Install went just fine. I did have to loosen the fuel filter housing before installing the new Frx block to the housing. I did not have to remove the A/C like most people. Actually when removing the factory one, it seem to have more spring pressure. Truck revs much quicker, but I did the IAH mod at the same time. I could not believe they put such a large object in the intake, what where they thinking.
