i'm working on a 1955 T Bird that hasn't had washers hooked up . i have figured out that a new washer diaphragm was needed and a casket for the cap. now the problem. 1 hose from bag goes to diaphragm, the second hose is to go to nozzles but i can't find a hole in the firewall to put hose through to get to the T for nozzles. if anyone can point me in right direction it would helpful.
