I blew one of those Trottle Body hoses on a 105o 4th of July.
It cost me big .
.
Replace those hoses ASAP with high quality hose.

They are no fun to replace down there between the firewall and engine when it's hot out and your engine is red hot with 2 newly blown headgaskets cause you didn't replace them on rebuild.
