EVIL ENERGYFuel Pressure Regulator 6AN EFI Bypass Return Adjustable (30-70PSI)Global Recycled StandardGlobal Recycled StandardGlobal Recycled Standard

This unit is a suprisingly good value, I give this thing high marks for the 70ish bucks it cost me, however...Let talk about what this is and isn't. This IS a fairly well engineered (copy?) AFPR, its holds it's setpoint well, it flows a good amount of fuel and it works well in boost. For the average tuner this FPR will at least eliminate a rather annoying variable (stock FPRs). This isn't a high dollar unit, I dont know if I would trust it to regulate over 500hp or 1 bar of boost but your mileage may vary. It is very likely that it will NOT survive exposure to alcohol, don't even bother trying it, buy a high dollar proven alcohol rated AFPR if that is what you are up to.I installed this on the return side of a Ford 300 I6 Turbo with Ford fuel rail to AN adapter fittings, I simply gutted the stock regulator and welded it back together to act as a passthrough to this AFPR. I set the reg to 42 PSI, hooked it up to a vac/boost ref port and sent it. ZERO variation in the tune, VE numbers look way better, proper flow and pressure are now being maintained on both sides of the injector under boost. No leaks, overall happy.Things to note:TAKE IT APART, make sure there are no shavings, rolled orings or a bad seals, don't be a noob and file a bad review because you didn't do your job. this goes for any Chinese aftermarket car part (BOV, WG, etc.).Double check your work, torque all of the fasteners to a standard specification.Be gentile with the provided fittings, they are made from low grade Chinesium, they do work fine. The supplied hose is meh but I used it anyway and it's fine.Be smart, if you dont know what you are doing, talk with someone who does, dont just install this on your car or truck because you think it's cool. If you dont have a reason to install an AFPR then dont, the stock one is going to work better in your application.NO ETHANOL! You didnt read the whole review, STOP!

This fuel pressure regulator was the answer to the fuel pressure that lacked while driving. The vacuum sensitive portion made the difference. Static fuel pressure does not work well for drivability.

Hardest part was figuring out where to install. Building the hoses is a little tricky, note that one piece is reverse threaded. Once I got the hang of it, it was not bad.Easy to adjust, apparently works just fine. Gauge is nice, easy to read.I moved the gauge to the side with a port extender, for clearance.

The lines and fittings that come with this are garbage. I fought them for a bit and went out to buy decent fittings at the parts store. We put a fuel cell in my son's Dodge Neon dirt track car. The 1st gen Neon did not have a regulator and return on the fuel rail so had to plumb this by the pump in the trunk. It's accurate according to my Hobo Freight pressure tester. Car's running well so must be close on pressure.

Started leaking in a few months. Nothing like a good ol' fuel leak going down the road on a hot summer day. Definitely buy this though if you like your fuel regulators to leak. If you happen to prefer your fuel regulators don't leak, check out the Aeromotive regulators, that's what I used to replace this Chinese rip-off junk.

Great product

Great bargain good quality

I used this to build my VR6 12v Turbo setup, and it works, but just enough. I've had it for a few months now.Pros:- Works well when the car is running and reacts to boost pressure well. I've ran it with 12psi so far.- Value is great compared to more well known brands.- Comes with some basic hardware to help with installation.- Didn't find any metal shavings inside it.- Adjustability is dead simple.Cons:- Does not hold pressure if the car isn't running. After a bit of the car sitting not running, it loses all pressure. This means it will cause the car to fail to start up the first time, or stumble.- Included braided AN hoses while thoughtful, are useless.- Included AN fittings work but I would upgrade them to better quality ones.- Mounting brackets could be a bit more creative for easier/better mounting. I had to weld mine to allow it to mount properly.I'm still using this FPR but plan to upgrade to something like an areomotive soon. I don't like that the car can't be instantly started if it's sat for more than 30 minutes. I did disassemble mine after I got it, and while I didn't find any metal shards in mine it's still good practice when buying anything cheap like this. As other reviewers have noted, the SS braided hoses that come with this kit aren't really useful, and are oversized, I'd reccomend ordering more AN6 hose instead. I got a 10ft roll and it worked fine for me and my Jetta.TL;DR: It works, just plan to upgrade.
