Broken o-ring in tbi 4.3l 46 gm extreme flooding

Asked by Oct 10, 2016 at 11:46 PM about the 1994 Chevrolet Chevy Van G20 Extended RWD

Question type: Maintenance & Repair

Today I pulled out my fuel injectors since one of
them was clogged up. Got that part taken care of,
minus one oring at the injector sprayer. Ran rich,
but fine. Got to auto parts store for oring and was
sold one that thicker, but same diameter. I was told
it would stretch a bit. It did not. It broke the
housing and from that point it began to spray gas
unctrollably. I tried several things to rig it to get me
home. Nothing worked and i ended up flooding the
engine very bad. Not having much luck finding the
fuel meter housing. At this point, im not sure how
to get all that excess liquid gas out of the engine.
Any ideas?

The safest way is to just remove all the spark plugs and let the fuel evaporate overnight, or if you have a large bottle of CO2 blow that into each plug hole until no more gas comes out, but not everyone has that handy. Your best bet on finding a replacement housing is a wrecking yard, you might have to overhaul it so look it over carefully.

Unfortunately I had to leave it parked at autozone for the night. I have to find the housing before i can go any further. Otherwise im sure it will flood bad again. Thank you for the input, I plan to call around again tomorrow and maybe hit a few salvage yards. Hoping for luck.
