As per title really, I'm after a low pressure fuel pump, 4psi or above will do for a carbed V8. Anybody goy one for under £25 posted by any chance?

Have you tried Facet pump ? They are good and cheap. I'm French and the company I'm working for import them from the UK. the company in the UK is Glencoe Fuel System Enterprise. http://www.fuelsystem.co.uk/
Hope you'll find what you want.
Cheers.

I've got one you can have for £24.99. In fact you can have it for free if you come and get it! It's a Facet and looks like it's been on the seabed since 1975 but it works!!

whitby is a bit too far to come.
