i bought a prosport mechanical boost gauge and it came with small vinyl tubing for the boost line, i believe its 1/8" but it is not long enough to reach the gauge. i went to autozone, ace hardware and lowes and the smallest they had was 1/4". does anyone know where i could find 1/8" tubing?

 

You could always just get a 1/8" npt to 1/4" barb fitting at a Hardware Store and just run silicone or rubber vacuum hose to the "T" fitting. That would eliminate any issues you might have with the nylon hose kinking.

 

well the only problem now is the 1/4 is fine around the tee but around the solenoid on the boost gauge it seems like it will slip off when i am running higher boost. but yeah im gonna check out for some vaccum line see if they have it that small. i think i could just run that all the way through..

 

That's strange my autozone had a huge roll of the tubing. They had it behind the counter. The outside diameter was different but the inside diameter was the same. It was like 9 feet for 5 bucks

 

throw 2 zipties on where you think it will slip. It won't come off.

 

the ziptie didnt feel tight enough around the solenoid i already did it around the tee and thats fine.
