Simple green along with a brush and a rag does wonders on grease and oil residue, but won't do much for any corrosion. A medium firm brush like a wheel brush seems to work best. Rinse with water first, spray on a strong solution of Simple Green and start scrubbing. Be careful around sensitive electronics, cover where needed. I use a garden sprayer to rinse with to better control the spray.

Diesel Power Products has your fuel rail for $316.00 US. Geno's garage has it too.

Best to disconnect batteries:wink2:
I use engine cleaner and pressure washer, blow/air dry then spray silicon spray on all connectors.
Replace lines, Cummins OEM, there have been updates, fuel rail if sensors, good I would just clean.

 

Picked up some Simple Green today, figured id get the pressure washer stuff as whatever I don't use I can use on some equipment. How much do people dilute this stuff? I read the label and it says about 2 cups to 1 1/4 gallon of water. I'd probably just do 50/50 and see what happens.

I'll try and clean up the fuel rail and just replace lines when I do injectors in the fall, hopefully.

I'm very cautious about water on my truck, I had a 5.3 vortec that had no start after cleaning, about $400 later it started.

Thanks guys.

 

Simple Green Ratio



I typically use a 50/50 ratio on a real dirty engine but found it doesn't really need to be that strong. I've had to use a 25/75 ratio when I was running low and it seems to work as well.

 

I agree with not using water, seems like a bad idea with electronics in the engine bay.

I have replaced the #4 injector line with the updated one and I feel like it is much better than what was previously there. Would be nice to upgrade to a 6.7 rail and lines but it is not necessary.

Did you get that price from a cummins dealer?

 

Yea I got the price from the dealer for the rail which isn't that bad I guess, but I figured the lines wouldn't be cheap either. I planned on using a spray bottle to make it easier.

Windy Saturday and rain all day Sunday so looks like I'm doing it next weekend :frown2:
