I'm wanting to use the brake booster hose for my vacuum source. Anyone know what size tee I should get?

Thanks

 

i need to know the same thing... bump

 

If you go to Pep Boys they sell the plastic T that you cut to the size you need, but the opening still wasn't big enough. Home Depot or Lowes, sell 3/8" barb fittings with a 1/4" NPT male. Buy 2 of these and a 1/4" barb to 1/4" NPT and a 1/4" female T and some teflon tape. I'm sure if you check online somewhere they might make a T with 2 - 3/8" barbs and a 1/4" barb, but I didn't look. Anyway, 3/8 isn't a super tight fit, but it's snug enough. As far as I know, there is no size inbetween 3/8 and 1/2, so I went with 3/8. Use hose clamps, not zip ties.

 

thx man!

 

No problem. You might want to check to see if they sell 1/8" NPT to 3/8" barb fittings. The inside diameter will be the same, but the T will be smaller since it's 1/8" NPT.
