60 psi Boost pressure gauge. Includes tubing kit for installation.

Extension only makes it far easier to R&R the Boost stick since the LLY sensor is buried down in the valley.

Boost sticks have been discontinued, but we still have some extensions left. I would highly recommend tuning boost via the ECM with my Kennedy Custom ECM programming. -JK

Fits MOST GM gas engines and some 1998 and later 6.5l engines as well as the 2017+ Duramax L5P.

"The GM 6.5 could have either SAE or metric plug. To determine which valve you need, it is best to check the thread pitch, but you can also tell by the size of the head on the plug provided it is not rounded or damaged. If it is 9/16" then you most likely have the 1/2" NF plug (EZ101H) and if it is 15mm, then it is likely the 12mm 1.75 pitch (EZ107H)" - JK

Applications for most any Domestic and Import vehicles as well as Industrial applications available.

"We equip these valves with the hose end as standard equipment. It is not necessary to use a hose. Having the nipple controls the flow and extends it further away to prevent splashing." -JK

Set of 8 brand new Fleece injector supply lines lines. Replace all 8 when doing your injectors. Yes they are expensive, but note that pile of rusty crap that you found in the injector inlet came from these lines. Rust and debris will build up between the line nut and the line even in the gentlest of climates. When the nut is turned will grind up this debris which will run down into the injector inlet bowl. Cleaning is impossible to do properly and any media blasting will leave embedded debris that will dislodge over time. New lines are plated to resist this rusting, but a good preventative after installation will help protect even further.

Emergency Road Treatment specifically formulated to dissolve gelled fuel back into solution and return the flow in approximately 20 minutes.

"This product is for emergency use only. It contains those potentially "harmful alcohols" that you hear about, but if you are stranded, what are you going to do? Using this in an emergency will not doom your injection system, but long term use could definitely cause harm." - JK
