Guys

The 5.3 vacuum port for the power brakes is 1/2" ID. Im having a heck of a time finding this hose anywhere. Where are you guys getting it?

Im trying a few experiments to adapt the 1/2" nipple down to 3/8" too but if that doesnt work, im gonna need that hose.

Not even these semi truck parts guys have this stuff!!!!

thanks

Aircraftspruce.com has it, go to site and search vacuum hose. Would think PVC hose should also work??

1/2" heater hose and a 1/2 to 3/8 heater adapter works fine.

Here's some thoughts on that subject from a week or 2 ago...

My intake/fuel lines/etc are going into a car with manual brakes, so I won't need my booster hose (if your looking for exact fit for 4th gen f body). There are probably others near you with parts laying around. Best bet though, is to get 1/2 inch heater hose or oil hose. The latter can be found at any hydraulic hose shop (several Car Quest locations have them). Heater hose is at every auto parts store.

I could NOT find this stuff either at any parts store or GM dealer.
I did locate Eaton "Easy Couple" Hose 1/2" - PN H20108 at a heavy truck parts shop. It is nice and flexible and is rated for full vacuum. Costs about $1.50/ft. It's also available in other sizes including 3/8".

"Eaton’s Easy Couple Hose, H201, is an excellent solution for general purpose, low pressure air, water, oil and fuel applications. In addition to the new higher working temperature rating, sizes 4 through 12 will carry a full vacuum rating of 28 inch/Mg. Note size 16 will not carry a vacuum rating."

I used a Dorman #47082 connector, and a short piece of 1/2" heater hose.
