I took the fuel lines off the top of CSEFI fuel meter of my 4.3 in a 98 S10 blazer. Now I have the following pieces and don't have a clue what order they go or whether they belong on the supply or return line side before the lines are inserted. The loose parts are: 1-yellow o-ring, 1- black o-ring, 1-sst ring and 1-plastic sleeve. In looking at the fuel meter body in the return (smaller) line side I can see a similar plastic sleeve at the top and a yellow o-ring below it. Do all the above mentioned loose parts go in the supply (larger) line side and if so in what order from the bottom up? Is there supposed to be anything above the plastic sleeve on the return line side? My haynes manual doesn't give any help so thanks for any help you can offer.
