TR DIESELFuel Pump Pin Governor 5.9 L 3200 RPM

There are some pros and cons to this combination fuel pin governor spring kit,I ended up with some crossover from the governor spring in the way of pre-boost smoke that I in no way could tune out, The fuel pin ramp surface was incredibly rough from the get go, but with the help of a Dremel I was able to use a wheel to buff and clean, It came out pretty well.To really take full advantage of this pin the top of the AFC should be machined flash To illuminate off boost and idol hazing,I ended up pulling the governor spring back out because as I said before I had smoke issues with mid throttle under load that would not clear up no matter where I adjusted the star wheel and this is not my first rodeo with a 12v.The redeeming value of this kit is the fueling profile ramp which is excellent, in conjunction with the stock governor spring it offers excellent low-speed smoke control and awesome top end performance.Would I buy it again? Sure would, for the price and the end result.

Fit my 93 d350 and made a difference. Keeps up with traffic a lot better now. I'm able to spin the wheels now. I was able to tune out the smoke, so it should have no problem passing az emissions. Very happy with this kit for the money.

Good buy

The gov spring is to short and will cause your truck to rev at full throttle after install. After stretching the spring 1/8th to a 1/4 inch in order for the truck to not run at full throttle. Other then that the fuel pin fit and works great. I would recommend buying from a trusted company unless you want to spend the weekend in the shop scratching your head.

Awesome

Could tell the difference in power. And rolls some coal now.

no governor spring was included just the fuel pin

Received package and fuel pin has surface rustSpring does appear to be a lot smaller but won’t be able to test as motor is getting rebuilt
