thanks for all the help so far guys
I should have mentioned I already have the 044 pump and fuel filter (sierra cosworth) , I plan to have it mounted it the pick up bed (with a cover so will be water tight ) this would be on top of where the tank is but I guess that does not matter as the cars have them in the same place .
the reason I am going to get one is I use to get fuel starvation when it was a diesel , but with pinto engine I had in after that I did not have any problems but I think that's down to the carb having a bowel so it was ok , but don't want to risk the cosworth engine .
