Ditch the regulator, use the stock bypass filter if using a mech. fuel pump. You either have binding linkage or your return spring(s) are too tight.

what brand of fpr are you using and what type of gauge? A gauge with fluid in it will work best. Assuming you are using the Holley FPR, right? As was mentioned, you don't really need it. I ran with the holley at first and had few issues, but ditched it and have never even noticed it. The OEM filter is an FPR. As long as you are using that and a mechanical pump(as previously mentioned) you won't have any issues.

Find a helper you use the pedal while you watch the linkage. I had some issues with my linkage at first. I had to install an extra spring and had to adjust some of my linkage, but it works good since. What part of the state is Bishopville in?

thanks for the input guys my stupidity was the reason for the regulator not working i was trying to tighten and loosen the hex key without loosening the bolt under it, i am using a holley fpr with a mr gasket gauge btw, taking the gauge out and plugging it when i have everything worked out

still havent figured out the pedal but i guess ill just have to get used to it , jeep has a lot more power im very happy with the swap

bishopville is on the eastern shore 5 minutes from ocean city

A picture of your linkage setup would be a great help.

I see an engine bay with many of the parts that are found in one, a good portion of a fairly good size garage with a boat inside it... then over here we get an obscured view of a rod.
