I don't think the pressure is very high on TBI. The vortecs use like 60psi but I'm thinking TBI is like half that or even less than that. A o-ring kit from the parts store might be the thing to get. Still not sure what type of o-ring it is, been too long.

I think the pressure is between 12 or 13 psi, don't think there is an o-ring at the connection, it's more like a ANSI fitting or seated flare.

It may be that you have a flare fitting instead. Not sure...

You might think this is off the wall but the details of this thread are interesting . So, when you slow down it bogs down. Take it a step further, when you apply the brakes or just coasting. If it bogs when you apply brakes, possibly you have a problem with the booster pulling to much vacuum and the engine is not recovering causing it to bog down.

Yeah that was one that I wanted to try but how do I test it? Not something easy and cheap that I could just replace you know? I hear know hissing up front like there is a leak when I press my brake peddle down at idke and then relase it as it is releasing the idle jumps a little but nothing major.

pinch the booster hose closed and see if the problem goes away. You will not have vac assist while it is pinched.

I had the hose unplugged and hooke to a vacuum gauge and the problem was still there would'nt this be the same thing? Thanks' guys for ideas it really helps
