So I take the top half of the plenum off... then what?
disconnect fuel supply first? Not necessary if you are quick
take fuel rail off? yes only a couple of bolts
do injectors just plop in or are they bolted in? Remove clip, Plop out
do I need to get new rubber o rings on the new injectors? No new o-rings
should they be lubed with something before putting them in? No lube
reuse the same plenum gasket? is that the only gasket here? re-use, try not to damage as they are f#$king expensive
If you've got one gone...the rest follow quickly, my advice is to get some splitfires.
I've got 5 R34 ones spare all of unkown condition...a couple are buggered, if you can be bothered figuring which are OK you can have them all for $75
Bingo, where I work that is the biggest problem, everything must be grounded as the flow of solvent produces it's own static charge on the containers as you fill them.
I don't want to be around here if 500,000L+ of solvent happens to go bang!
Dunno the seats look like my ones...the type that easily stain and get brown water marks LOL..but I've found some stuff call Orange Power stain remover gets them back to new!!!
