return line kink?

[bryanjeep]

I think I finally figured out why my engine has been running like crap for over 1.5 years. I had the fuel pump replaced by a mechanic 1.5 years ago :? I know I know! I didn't feel confident with that type of stuff yet. I am capable of anything now . Yeah whatever...

Back to my story, I think they kinked my return line when they put the tank back on. So I have to lower my tank tommorrow and check it out. ANYTHING IMPORTANT I NEED TO KNOW? I got to this idea because I hooked a pressure gauge up to the rail and as soon as I started the Jeep, I pegged out the 60 psi gauge. It still wanted to read higher than 60. So after yanking out the rubber return line from the metal line under the firewall on the frame, I noticed the pressure gauge read at a normal 35 psi.

So here is what I know. It is somewhere between the place I unhooked the line and the tank. I examined the line to the tank and it looked ok. I guess the idiot mechanic smashed the return line when he put the tank back up. SO AT LEAST I HOPE THAT IS WHAT IT IS. It has run like crap since then and that must be what it is. Are there any common places a return line likes to kink up on you? When taking the tank down, is there enough play on the lines on top the tank to pull it down to the ground?

Sorry for the long story, I just hope that is what the problem is. Any comments please...Bryan

just make sure the tank ISNT full. there should be enough slack to lower the tank. if not the lines are not hard to dissconnect. they use small o-ring clamps. you will have to dissconnect the fill tube. one big o-ring clamp. i am sure i have forgotton something but it has been awhile since i dropped my tank.

Once you have the tank dropped, disconnect the return line at both ends and shoot some compressed air through it from the engine end if you think there might be something in the line.
