Thanks Nauli. Im thinking of buying a refurbished set, just for peace of mind, or failing that just the o ring kit.
Would your injectors fit the OEM fuel rails? And pardon my ignorance, but i would tune up for them?
Actually since iv been running with a leak, would you reccommend i get a check with mms anyway if im able to fix my leaks?

Im tryig to knock it back together before wednesday as i have a shoulder operation and probably wont be able to work on it for 6 weeks after
