hi all, guess what? i decided to take the top off the pump and give it a tweek as mentioned and :shock: the diaphram has got a split in it :( so i got on the phone and called my nearest land rover parts shop, jl services, and they said they cant get them as it doesnt have a land rover part No. :? ...so were do i go now? any ideas? has anyone got a spare? can you tell me what this little split is actually doing?
Budgie:
If you've got a split in the diaphram then it will keep the fuel delivery to the injectors at it's minimum level. So as you put your foot down, no extra fuel is getting through.
The diaphram uses a vacuum from the turbo to raise it and increase the fueling, with a split this won't happen and thus you get poor performance. :(
The injector pump is a Bosch VE pump and there are a few diesel engineering places in your area that should be able to help.
Go onto the Bosch website (Here) and click on the dealer locator at the top. :wink:
