Just got my kit yesterday and put it on this morning. I used the gold spring and the truck runs great. It realy isn't that hard to install the kit, BUT dont drop the spring and piston or much else in the lifter galley, you will pay for it. It took me an extra 45 mins to pull the fuel bowl and reinstall it after I droped the spring and piston. Put a rag under where your working. Note to the wise.

 

If some of you guys, havn't installed your FRx yet, nows a GREAT time, to hold off, and order the fuel bowl rebuild kit / cabinet mechanic o-ring kit, and rebuild it, while the bowl is out. Makes much easier also, to install everything/fpr and spring.
