anyone know a source for a 3/8 ck valve-my power brakes are a little weak with the new engine, so i might raid the junkyard for a vacume pump, tee it in to the hose to the powerbrakes, but leave hooked up to the engine with a ck valve so the vacume from the pump doesnt go back in the engine-looking for some kind of universal one with 3/8 hose conn on both ends

 

Check with Mcmaster.

 

Russell,The hose and fitting company,I use one with my large tank,I bought 4' of 4" PVC pipe and two pipe caps,Drilled and tap one of the caps for 3/8 pipe thread.Mounted it right behind the front bumper(you can't see it)used a russell #6 check valve at the engine and Russell TEE at the master cyl. Work great....PM for more info....Oldhead PS:I had a Vacuum pump to loud and ran alot

 

do you have a part # for the russell ck valve, i couldnt find one on their site-thanks

 

Make that "EARL'S" for a blue one #250006,for a red Earl's is owned by Holley Try WWW.HOLLEY.COM...Oldhead

 

thanks Oldhead, i was going to try a tank first, def dont like the elect pump, had one on another car, didnt like it, but dont know if the tank would really help that much, but since i have one gonna try it anyway-might even use hydro boost, since i have p/s-i kind of though maybe an elect pump with a storage tank might cut some of the running,
a cold winter for sure, so plenty of time to try stuff, lol-i have 13" of vac at an idle, thought that would be enough, but doesnt seem to be

 

I have found that below 8" of vacuum the brakes stink,above 9" there good...If you bought a tank they are small 5" round,7"high....The one I am telling you how to make is 4" round, 36 to 48" long.....Size does matter OldheadPS: Just think about having one 48" long

 

I was going to do this a while back ............... Was told it could be done on the cheap with a junk yard piece . I never pursued it , but it could be just the ticket for you

 

i bought the alumn. adapter bracket a while back made for a chevelle, prob pick up a hydroboost off an astro van for around $75, then just the price of hoses and ends, so i can do it cheap, i'll see what i end up with

 

I have a hydroboost PS pump on my truck. I am using Vacuum assist(95 silverado brakes). If you have a non-hydro PS pump maybe we could figure something out..but I wouldn't touch mine till spring

 

Not to barge in but I don't think pumps are different except for maybe 2 returns, but is not necessary as long as you T in p/s and hydroboost before pump, early ford hydroboost had a unique pump but later just used same pump with a T.

 

I used a check valve out of a 90 honda civic brake booster line. It's a perfect 3/8 barb on both ends, worked great and it was free!
