Todd's Tech Tip Quickies: How To Pressure Test A Motorcycle Gas Tank With An Old Torch Regulator

[@kurtfoulke5130]

Probably one of the most useful tech tips that Todd has done & definitely One of his funniest 😂

[@jamesbarca7229]

Good tutorial. You can get a mini air regulator with gauge like the one I use, for just over ten bucks at Home Depot It's already set up for 1/4" fittings which makes things simple. And, like Todd said... 3 psi, and definitely no more than 5.

Thanks for the helpful video, Todd! I have a set of old Harley gas tanks I need to test before painting them. Perfect timing!

Hey Todd, I hope you have another Saturday Sportster series in the works.

Did basically the same thing except I used a bicycle pump.

THANK U i must confess my frisco tank did leak that i got from u guys . i filled mine up with water and let it sit over night i will do this next time around

[@lowbrowcustoms]

It happens, thats why we always suggest to test them. It's cheap insurance. Humans make mistakes ya know.. these tanks aren't all made by robots. :)

No lie on using a precise regulator and not going over that 5 psi limit! I made the mistake of trusting my air compressor regulator and guessed where the needle was since it started at 20 and wasted a great tank that had just been ret-unnled. Luckily my friends welds held up and I didn't die Super scary stuff!

I cut my Tiger tank apart and added 2" down the center. Maybe i should test it,lol.

[@lowbrowcustoms]

yes yes you should lol

[@digschopper9321]

@@lowbrowcustoms actually did, at about 6psi, and its fine. Holds just short of 5 gallons now without looking fat.

Great Tutorial.... Love your stuff. Bookmarked

[@chappledesign]

Todd, I wish I would have seen this prior to recently painting my bonnie tank. Ask me why :-O !!

[@mickey-eq5vw]

Can you guys do a vid how to change a stock sportster tank to a custom tank with a petcock on the bottom left or right side.

[@lowbrowcustoms]

Saturday Sportster, check it out two different series, both do installs on tanks. we also have a triumph install tank video on here as well. Have a look in our videos section on here

I do not have access to air compressors. have a 70 yrs old tank from a Velocette, been restored, no visible rust. It has very small seep of fuel at rear end around the frame opening. Tank is put together by tin-soldering, not welding, so cannot be repaired with welding as it will overheat original joints, melt the solder. Cannot seem to locate it using air pressure (by blowing into a hose into tank or use a MityVac type pump) and soapy water. Even tried immersing that end of tank into a large bucket of water while pressurized...no bubbles seen. I put a gallon of fuel back in and let it sit overnight with baby powder on the seams and found a very small discoloration on powder next day in one spot. Hit that with epoxy to seal on outside but have since found there is another similar leak nearby when I have fuel in tank on the bike. Cannot seem to locate it using testing methods I've tried...thinking maybe only appears when tank is bolts on bike...some flexing maybe happening. Suggestions?

[@sportster88]

It sounds like you need to find a good radiator / gas tank shop to boil it out and solder the seams for you.

🔊Hello Todd! No tanksealer?? Why?? Please explain👊🏻

[@lowbrowcustoms]

Only need tank sealer if you got lots of rust in there. tank sealer doesn't plug up holes.

[@blackrabbithandcraft4124]

I bought 3 different tanks from you guys a 2 had holes. Very disappointed especially since both were welded then brazed and still had holes. The third seemed great painted it got it just right bolted it on and the tab cracked the tank ruined the paint. Please test your tanks a little better.
