Has anyone ever deleted the complete egr system off a cali lb7? I will be putting a pro fab y-bridge and intercooler pipe on. I was just wondering if anyone has ever removed the vacuum system or any of the sensors on and around the fuel filter?
you have to leave all the sensors pluged in by the fuel filter. if you dont service light will come on. i did this on my lb7. make a big diff. also if uyou take egr off total off you need a diff pass side up pipe
Sensors stay unless you use EFI. I changed 1 idler, and removed pump on mine. Shorter belt and new up pipe and intake horn. Only other major difference between it being a federal truck is in the heads....less flow on a Cali truck.
We took the vacuum pump off my dad's truck after it started making noise. All we used was a normal belt, and yanked all the vacuum lines and sensors. We will eventually do a full delete
