Excellent installation instructions.
Reviewed in the United States on July 25, 2023 by Joe
My first diesel experience. Not a diesel guy. Can tear a gasser down and rebuild it but was nervous about diesels. Great instructions easy install. Don’t have a FP gauge so couldn’t tell you that aspect but replaced the oem spring. No problems. Big blue housing looks cool under the hood 👍🏻 *edit* Still can’t express how important a fuel pressure gauge is!! Had this on for maybe a year? Lost an injector and while it was down and before I put new injectors in I added a gauge found out I had little more than 30pounds. Took this apart and the larger o-ring had deteriorated and a large chunk had become lodged in the plunger, a wonder I had any pressure at all. Not sure if it was the biodiesel ,which is all I can get, or what but the boring didn’t last. Add a gauge and don’t just trust that this will fix it and you won’t ever have to worry again... all that aside I’ve now replaced it with sinisters regulated return

All parts included, minus wrenches, to upgrade factory parts to this blue billet blue spring mod. Installs in and 40mins. Highly recommended. Will update if anything changes. I saved $27 buying it on Amazon vs manufacturer site.

Nice product 70 psi after install. If you have a fuel gauge sender, the billit housing is really thick and this required a small extension to keep the sender from hitting the regulator housing. With that said, great quality and does the job!
