I was just wondering i have a mk3 escort and i put the s2 turbo tank on to it for the swirril pot as i converted it into a zetec. I was wondering if the mk4 escort filler neck would fit straight onto a mk3 escort?, Also the the plug on top of the sender is missing for the guage, but i can only see 1 wire there, is there only the one wire goes into the plug for the sender? Cheers Ben.
