Thread: Hose question

the large vacum hose on the back of the VE intakemanifold that runs to the brake booster whats the inner diam on that? is it 3/8 or 5/16?

Hmmm good question I think it's 5/16. Might have to take yours and cut a small section out and take it to the auto parts store wit ya

real reason is i am going to use it for my map sensor and i need to buy some sort of T fitting. i would like to use a fitting like the fuel pressure gauge T but i cant seem to find 5/16. so i was hoping it was really 3/8.
