I recently had to replace my fuel pump. Had to drop the tank and cracked the line that feeds "overflow" fuel back to the tank. I'm assuming that's what it does since it connects to the hole in the fill pipe at the top. I tried to repair it to no avail. I left it disconnected. Now I have an issue with extremely slow fuel filling. I can't imagine that line would cause that problem. It's like it gets enough gas into the fill tube, then shuts the pump off. I have to wait a few seconds before I can do it again. 20 minutes to get a half tank. I checked the charcoal box air flow, and it seems fine (passes air without restriction. Replaced the esim valve, and my reader shows it opening and closing. I replaced the fill hose, thinking that it may have collapsed just enough to cause the problem. still no joy. I also checked the anti-syphon valve, and it appears to be working correctly. Any ideas would be greatly appreciated. Thanks

 

That's a vent hose, and without it, you run into exactly the problem you are describing. Need to replace it. Local parts store likely has the appropriate hose in bulk.

 

youre are right that its a vent hose but not one they have in bulk. The line is the pressure type connectors and a hard plastic line. The part that brok is actually the nipple on the tank. The only way to "correctly" fix it is a new tank. That part is not sold. thanks for the info

 

Could you epoxy, or plastic weld it back together?

 

I tired JB weld plastic bonder and plastic epoxy. Neither of them held. I had a lot of success with the plastic bonder in the past but i may need to use a lot more for this to hold

 

I wonder if testors model cement would work? It actually melts the plastic together. Chemical reaction, not heat... though it does get warm for a bit, but, not dangerously so.

 

Is there an indication of what type of plastic it is? I've had good luck with ASA and ABS using SciGrip Weld-On #3 and #4 solvents. They do like HeyYou mentions and fuse the compatible plastic materials together.
