Cheap Fix for a Plastic Gas Tank Vent Pipe with a Few Small Holes???

My '06 Tundra DC 4.7 has a PO441 & a PO455 code. Had it checked and there are a few small holes in the plastic gas tank vent pipe. It was recommended to get a new tank as the hose is not serviceable and one of the holes is near the gas tank. Is there a way to just repair the hose? From what I have found online it looks like the pressure is only about 2 pounds. The tanks are about $1250 plus whatever brackets and extras are needed. I'm afraid many junk yard tanks may be in the same condition. Any input is greatly appreciated. Thanks.

 

Steel stick it or plastic jb weld

 

Another vote for JBweld or any flowy epoxy you can find that won't dissolve with constant gas vapors.

 

How would you bridge, or cover, the holes when you use the JB, or are you talking about the putty so I could just mold it?

 

Putty probably but you could just glob on the plastic jb weld it's pretty thick.

 

Are you talking about this?

Yes, thanks, exactly that issue.

 

Amazing. This forum never disappoints.

Good luck with the fix.

 

I would either use a section of fuel hose or try 3M Temflex 2155 rubber fusing tape.

 

A thank you to bfunke. I wanted to update on this fix for the plastic fuel tank emissions pipe. I filmed the whole pipe with my phone and found there were 3 different "Holy" areas. One near where it joined the tank, one around the middle, and one near the fuel fill end. There were 2 that were about 5 mils across. It's impossible to get a direct view unless you remove the bed. I was afraid that with the epoxy putties I might end up plugging the pipe since you are doing it completely by feel.

I read up on the Temflex tape that bfunke had suggested. I had never heard of silicone self-fusing tape before. I did some Googling and found a very similar tape that is listed for auto and marine use and is chemical resistant. I found this on Amazon,

$18 Proxicast Pro-Grade Extra Strong 30mil Weatherproof Self-Fusing Silicone Rubber Sealing Tape For Outdoor Antenna Coax & Electrical Cables, Hose/Pipe Leaks & Emergency Repairs (1.5" x 15' roll) - Black

Amazon.com: Proxicast Pro-Grade Extra Strong 30mil Weatherproof Self-Fusing Silicone Rubber Sealing Tape For Outdoor Antenna Coax & Electrical Cables, Hose/Pipe Leaks & Emergency Repairs (1.5" x 15' roll) - Black : Electronics. 15 foot roll for $18. The one side looks similar to a silicone automotive hose. I cleaned the pipe up as good as I could with isopropyl alcohol and applied 2 layers of this tape. Fairly hard to do only because I have huge hands, you are working blind, and it's a pretty tight area. Very simple though. I now have 200 miles on it, no CEL, and I got it emission inspected today. Yay!! Always nice to be able to do a repair on the cheap yourself, as opposed to a several thousand-dollar repair to replace the whole tank. If it holds up, great, if not, I have a year to find time to pull the bed and splice a fuel line in before I need to get it inspected again.
