Sup guys. Iv been looking around n couldn't find a brand new I can buy. Mine is getting a Lil stiff n I think it's best to replace. Also it seems to have a check valve in it. So using a reg hose might not do the trick.

 

N aslo the vac hose that goes to the block.

WIth my RX-3, I used fuel lines, cant remember the exact size

 

Take the check valve out of the oem hose and insert it into the appropriate sized new one. Since it's a one way valve, you should be able to blow though it from the intake end but not from the booster end.

 

the wacky or mel.. lol i think its 3/4 od. but ill check on it tomarrow

thx trochoid i blew air into the hose and air only went this way.
(away from the booster)



so all i have to do is shove the check valve in the hose facing the right direction.

and that check valve is wat i need if im going too boost my motor right?

 

You need the check valve no matter what. Vacuum from the intake is what charges the booster. I'm not sure, but the TIIs may have a different check valve, You'll need to check the parts fiche and compare the part numbers between the NA and TIIs
