how to adjust a TD42T fuel pump

Post by GQ4.8coilcab »

how do you adjust one. Is it just turning the screw on top of the pump to add more fuel. I know you need a dyno tune so u can get it acurate but im just curious what bolt they actually move. Thanks Julian

The TD42T pump may be different. I don't know if it's got a boost compensator device ...

First of all, Im no expert. That being said, I guess the TD42T pump should be a little different. Ive never worked on a TD42T pump since theyre not very common here. CAn you provide some pics of your pump ?

Aircon lever can be easily adjusted. Its sort of a lever on the front side of the pump. Usually idle speed goes wild when you provide more diesel...
