We'll thought I would update this think I've got to the bottom of the issue/issues
So things I replaced
Fule pipe front to back
Hand grenade
Fule filter (twice)
Pipes between grenade and filter and pump.
Seems to be loads better now, I filled up with Veg Oil yesterday 95% Veg 5% petrol and it seems loads faster than it did before and seems faster than it was on derv? Guessing it's the New pipe front to back might be slightly bigger so there's no restrictions. Would Defo recommend any one running veg to fit a thicker pipe really does make a difference!
