ok i'm not hot rodding this but the s10 forum guys are in disagreement as to my issue. i have the 2000 s10 2.2L vin5 truck and i had to change out the fuel pump. well when i did that and got it back running and test drove it i got home and the pressure line blew off the pump. so i put it back but then decided that this may happen again and put me on the side of the road. so i put it on the lift and took the tanks down and got some doorman repair endes. so because i have the old pump and before i installed the new pump i made sure the ports were these same the pressure was 5/16" the return 3/8" and the pressure 5/16" port internal line did go down to the pump i made sure of that. then i made sure the wires were the same colors and that they went to the same spots on the new pump as they were on the old pump. i did not want to have to take down again, and also because i had a time flinging that pump the did not cost 300$
so now to my delema. i got the lines all connected i did one at a time and i used doorman repair end kits and put them back on the pump and then fitted the barbs over rubber gas line. then ar the other end i had to fashion some brake line to fit into the old line at the filter and the rubber gas line. so then i started it and i had a leak parrell to the frame and sure enough it was the pressure line, for some reason it did not like just being clamped to the barb so i had to push it more onto the doorman line so it went over the complete bare and i double clamped it on both sides of the barb hump area. now i started it again and i found a leak at the filter center port so i got a new filter and put it in the same ports. then i started it and discovered the rubber gal line swelling some and i figure that is not good. so i double checked the hose rating and i'm be damned if i use 50 psi rated hose. so i have had a hell of a time findng a fuel line kit for this truck the filter has 2 ports on the tank side and one on the engine side.
so some guys i taked to on the carfix forums and the s10 forums are telling me i have the wrong filter or connected it wrong. so maybe you guys can help me out.
i figure if i hooked the filter wrong it will not allow gas to run the engine as the built in regulator will pass fluid in reverse it industry regulators are on way devices. i worked on hundreds of them in my 40 years. so today to calm the car fix guys i did this test see photos. and here is the filter i have see photos can you guys confirm to me the the center port is the inlet and the outside id the return. one for the carifx guys sen a photo showing the other way so it is possible i have the wrong filter but oth original fitler works as the one photo show. but the s10 guys are telling me i have the wrong filter but the gm parts site tells me by my vin i have the correct filter also if i did have it connected wrong that the engine just would not start and or run? of here are tons of photos let me see if i can get sub titles on top of each one for a description
ok this is the original filter that i tested today
this is the original filter that afrer i got the new pump and line installed i found this leak so i change out the filter
this is the original filter showing all the lines the rubber on the what i'm calling the inlet was for doing a smoke test to find that leak that turned out the where i have pointed out in the above photo
this is the diagram of how i now have this plumbed up
this is a filter the car fix guy sent me telling me the filter is wrong that i have new and original
the is the original filter you may see the drip between the barb and the filter
this is the gm site showing me the fuel line diagram and it sure looks like like 24 goes to the center port on the filter and they said it went there. but i'm getting a lot of conflicting stories.
my new filter with the same type of ports
thanks fo r any help on this if i was to take this filter off and do the same test with the air i bet i will get the same results as i do not belive the regulator will allow backwards operation. thanks
