Cheap Duramax Upgrades! Restrictive Fuel Filter Head Delete

A good cheap way to get a little better peddle response and high rpm performance out of your lb7, lly, lbz, lmm, or lml.
The barb I used but most anything will work.

Leave the factory stuff there and just add the tube just incase your lift pump dies, you can still drive the truck to repair lift pump down the road.

Thank you Bobby - great explanation.

If your lift pump goes out you’ll be stranded. My air dog went out one time.

[@ClarkeMotorsOC]

How long did it take to get the air out of the line, did you release it out of the Schrader Valve.

[@rydermaxwell7780]

How did you bleed the air out of the line

[@jeremiahlindberg6511]

Did you have any problems with the truck not wanting to start after removing the stock housing? Currently having problems with my truck not wanting to start. My CTS3 is showing my actual rail pressure is no where near the desired rail pressure. I also don’t hear the lift pump turning on when I turn on the ignition.

[@bobbyrebussini1466]

Well that would be your first problem. The lift pump eliminated the balls need to hold prime

[@bobbyrebussini1466]

You need to get that fass running and I’m sure you will start right up

[@angelberrios1730]

When you removed the old filter housing, all those wires left there won’t give you any codes having all that unplugged?

[@thatchevyguy7006]

No, one is for the fuel heater (won’t throw a code) and you can unplug the water in fuel sensor at any time and no code will pop

[@juliojimenez7126]

No, you should be fine

[@expatconn7242]

You put that back on even with a new lifer pump?

[@bobbyrebussini1466]

I don’t understand
