I've had a search but cant seem to find the answer. I'm going from MFI to Cossie Management on my S2 but need to know if I need to change the Fuel pump ? I know the S2 is an external fuel pump, but I've got a Cossie in tank pump from my last Fiesta, could I use that or would it be an uprated external jobbie I need?

Also as I'm doing un underside resto can I get rid of the ford bias valve thing for the rear discs and fit an aftermarket one just to neaten things up and save painting an re-fitting? I'm fitting rear discs and re brake lining the car anyway.

 

for the fuel pump im sure if u get a EFI escort fuel tank u can use the cossie pump?not 100% sure tho,better off just getting a decent replacement of wht u got,less hasssle!
if u just re pipe it thn u can loose the bias crap valve,but IMO rear discs are a unsafe and are crap,some argree some disagree tho on tht 1

 

I Run Rs Turbo Tank With Group A Cossie Fuel Pump On My Zvh,at 300bhp And Works Well. I Had Rear Discs On Mine And Found Them Realy Bad.back End All Over The Place.
