Speak to Chris Hawes - he sent his back and changed back to a -properly 
set up- original system.

You must have a pickup filter that isn't blocked, a baffle with only a 
small inlet to the rest of the tank. There must be a base to the baffle 
- early cars didn't have this (Hervey's doesn't still) and there're also 
clips to hold it down. John Hervey's setup might be simple but it 
doesn't work as well as an original one. I can pretty much guarantee 
that in really hot weather whatever setup you have will make the pump 
noisy. All the renaults use a lift pump that's actually designed to suck 
- ours aren't.
