Review on Ford 3C3Z-9T517-AG Fuel Pressure Regulator Kit for F-Super Duty 6.0 - All You Need to Know About 3C3Z9T517AG by James Mayfield

If Ford has an E Series Van kit I haven't found it. The return port on the vans faces forward instead of backwards like the F-Series, so the regulator housing included in this kit will not work and goes straight into the trash can. I was able to reuse mine by installing a new spring, piston, fuel return screws and o-rings from that kit. I wish the kit included fuel banjo washers and outlet o-rings to attach to each head! (Not necessary unless you're changing the spring, but it would be nice to change "while you're there".)
