Very nice fuel pressure regulator. Installed very easily and it adjusted great. It’s a way better product than the factory part.And no more replacing Springs when they were out.
Irving Salinas –
It works amazing! My stock setup was running 30 psi after i installed it it jumped to 100psi. Had to turn it down to a middle 80psi.

Nice product fit well and looks nice. Word to the wise tho check your fuel pressure after putting this on because mine was not set from the factor. I installed a 100 psi gauge when I put this new adjustable regulator on and when I fired it up the gauge was pegged. But backed it off a little and now it’s perfect. Tough spot to get to with the upper radiator hose in the way but turning the pressure up and down is as simple as turning the adjustment screw then locking down with the jam nut.

Was easy to install, easily adjustable pressure, no leaks or problems with bolts too “short” . Some people should stay away from wrenching, they are to heavy handed and they make righty tighty a righty loosy. Bad installs come from wanna be mechanics who should have had their wives do it for them.

Product is great but when adjusting the screw please make sure not to bottom out or over screw it. It will eat up the brass coupler where the blue spring inserts and push it all the way in to the fuel bowel. My gauge kept acting up after installing this kit. I went and disassembled the kit and found out the adjuster screw is limited to adjustment as the brass coupler can only sit flush with the housing and can’t be pushed back with the blue spring (obviously). Hope this helps anyone having issues.

Worked/performs great and easy install

No logo or adjustments, the spring isn’t even blue. But it has a sinister deisel sticker in the box. Im confused about this, and would like clarification.

It does just what it says it does but like others have said the 4 bolts are not long enough. Had to go buy longer bolts and than washers and what not to make it fit. Than a dremel to make the washers rounder.
