George - West Wales

Hi everyone.........

Have a P reg Disco 1 that needs a fair bit of tlc; am working through it, and when wanting to use the manual fuel lift pump (diesel ) to purge a new fuel filter, it appeared not to pump at all! Have inched the crank round a couple of times to make sure that the pump lever wasn't on the high point of the cam, but no change. Can this engine (300) run ok just using the low pressure fuel pump in the injection pump? Most odd!

Hi George, welcome to the Zone!!

The lift pumps are notorious for appearing to do nothing!! The best way I have found is to fill the filter with diesel then start the engine and the lift pump will pull things through fine.

Where abouts are you in West Wales?? I'm just outside Haverfordwest!

Thanks for that - I'm in St Dogmaels

Right, the lift pump had, actually, failed. The actuating rod had come adrift from the diaphragm and was just waving about in the breeze! It was a non original 'cheapy' pump which couldn't come apart, so it's been binned and replaced with another 'cheapy' pump!

Interesting though that the Disco has been running fine for two years - I think that rotary fuel injection pumps have an intergral pump (correctly called a transfer pump?) which must cope as long as the system is not drained partially, eg for a filter change.

Cheers
