I have a 2005 TD5 Defender, and the fuel pump is sounding like a very angry mosquito. I have just put fuel additive (read cleaner) in the tank, so will see if this solves the issue.
I have read about the fuel pump replacement that is in the P38 forums section, and am wondering if the 38mm high pressure pump will fit in the Defender set up.

I can source a new pump locally, and have it handy in case mine fails. Don't want to replace the whole unit including sender, and filter if not needed.

Thanks in advance

Cheers Ken
