This may be another dumb question but I still need it answered. Which line is the return? The one one the pressure regulator, or the one right beside it directly connected to the fuel rail? Thanks

I think I found the answer. The one on the regulator is the return. If I'm wrong someone please let me know. Thanks

Hey Que. just tested return line. If i was on the right line (the return, I was on the one off the regulator) the pressure dropped to 31psi. This means the line is pinched or bad, and not the regulator. Am I correct?

pinched line or there is an issue in the tank. you need to pop the return line at the tank and do the same thing. you should probably do the fuel pump access mod to get at it. there is a good chance the tank is warped and closing off the return at the bottom of the tank.

Ok bud. Looks like ill have a busy weekend. I traced the return to the tank and saw nothing visible. Didn't have much time to spend. I've been reading all these other threads with similar return problems. Still don't know what I'm getting into. We will see thanks again for hanging in here with me.

Oh yeah been researching it all day. I've got a factory service manual been looking at all week. It hasn't come close to helping like you guys. I'm gonna have to cut the door. I've had no luck with nuts and bolts on this thing. I think I'm prepared. Got a copy of mean max's template. Now I just need to get off work and get started. Ill post up how it's going.

Hey buddy I need your help. I pulled the pump and no blockage in the return on the pump. When the pump was seated in the tank it had blockage like a brick wall. Traced it all the way to the pump before I removed. Anyways. I have no clue what the plastic white piece on this inside of the tank looks like. Here are some pics. It looks warped up on the inside there on just the piece the pump sits in. I need some advice on what to do. Should I trim the foot off the return on the pump? I think I read another post someone else had done this. I don't know. Ill do some more reading before I make a move. Just kinda stumped here. Thanks

Pull the plastic tray. Cut back the return tube an inch and reinstall.

X2 yank out the plastic tray and trim the foot off the return line, where the big rubber thing is on the end of it.

Gotcha I read up on a previous thread and saw Pete give the same advice. Going back in with it now. Cleaned out the tank while I was in there replaced the strainer and filter. Ill hopefully give a final update tonight. fingers crossed!!! No other gremlins pop up!

Ok guys got it back in. Changed fuel filter, pump strainer, pulled white plastic tray, and cut an inch off the return, did away with rubber boot. Also changed spark plugs before I started it up. I had to cut the wires to the pump couldn't pull the plug through. Soldered them back together. Started her up and pressure was a smooth 31psi, without vacuum 42psi. Idles smooth as my new tacoma. It did have an erratic idle before. Runs a little better too. Little more throttle response when in the gas. In the pictures I'm posting of the tray you can see where the nipple of the return was bottomed out on the tray and wore grooves in the plastic. I wanna again say thanks to Que, and Pete, and MeanMax (for a spot on template for the access door). Without you guys I was lost. Thank you for all the help. You guys know your stuff. If I ever run into anything else (sure I will sooner than later its a yj I'm trying to work the bugs out of) I hope you guys will be around. Thanks again. This is the best forum with the most helpful, knowledgable people out there!!!
