TD42 Lift Pump
Posted: 23 Oct 2015 07:19
Ok so I have done a search on the forum, but could not find any info on this topic.
So I have noticed for a while now that my Patrol has sort of a hesitation around the 3,000rpm mark. If feels just like a engine with diesel starvation so I did a search on the net and found allot of the Australian guys have the same problem.
Sounds like after many years of driving there can be small leaks on the fuel lines which can draw in small amounts of air and can cause cavitation in the IP (injector pump).
This in return can cause your injection timing to be slightly retarded and will explain a few other thing I have noticed. Also the wear in the IP also doesnt help much and makes it a bit worse as well.
Obviously I will change the diesel filter first as well as check that copper inlet pipe on the IP as it can be blocked.
But for the long term it seems like there are quite a few benefits in installing a lift pump on the fuel line to supply the IP with diesel so that it doesn't have to work so had to suck the fuel all the way from the tank. People that have done this said that the power delivery accross the whole rev range was very smooth.
Any one done this or have this installed on their diesel?
