My 94 Toyota had a bad fuel pump, when I dropped to tank I also cleaned it out . When I was ready to put it back on I couldn't find the skinny fuel line that went on the fuel pump bracket but I found the one that goes on the tank. I noticed that it had some kinda check valve made in it ,so I hoped the missing one didn't have one too. I replaced the missing line with new hose and when I got the truck started it ran good but after a few minutes gas started coming out of the charcoal container on the fire wall. Now I'm wondering is this from have the wrong hose on it , did I put the 2 hoses on the wrong metal line since they connect side by side or what. Thanks for any help. Ed

 

I hope you used Fuel injection Hose and the correct clamps .to handle the pressure

Sounds like it is possible you reversed the hoses

We all sometimes forget to mark things at times
