2004.5-2010 GM 6.6L DURAMAX AND 2007.5-2018 CUMMINS 6.7L RACE FUEL VALVE

Problem solver

Dealt with low fuel rail pressure codes, 2 hours of fighting the factory valve with 320k+ miles on it. And it’s done to say the least.

Fixed rough idle

Was not to bad to install just need some strength had a very rough idle before install and low fuel rail pressure put this in took about a hour hour and a half and started up with a smooth idle.

Almost Perfect

The part came quickly with high-quality packaging and new O-ring included. Installed it on my truck but will have to wait to pull a heavy load in hot weather to see if it solved my P0087 problem. My biggest complaint withthe stock part and the aftermarket replacement is the bolt heads are too thin. I had to spend a day and a half fiddling around with a variety of tools and penetrating oil to bust the old one loose without stripping it, it is a very tight area. My recommendation is to put another eighth-inch or so on the bolt head when these things are machined! You also have to get creative when installing the new one so that it doesn’t go in under torqued.
