Id like just to say thanks for all the help and advice on here and via PM's with my Hippo which with its new fuel pump new battery and a few other bits and bobs is now running as it should, has gone up in my estimation,if in a few days it is still behaving itself i will never compare it to the old 1.8xei i had which frankly i wish id never laid eyes on lol.Im getting rather fond of my plum coloured Hippo and hope it continues.And yes i still hanker after a Disco again but my Hippo she aint that bad.
cheers again

Check your alternator again. As previously stated, even with a duff battery your charging level from alternator should have been around 14Volts not 11.5! A new battery may hide this issue, though its true enough that after a boost charge yr old battery should have coped much better.

I had a Disco too and though I miss the ground clearance off road, the hippo is a lovely car and a capable mud plugger to boot
