Hello All ..  1999 RD , 300 engine    Plastic Fill / overfill combination coolant fill tanks with STADARD pressure spring radiator cap, My Stant pressure tester cap is the correct diameter, However,    wont catch under the lip on the coolant tank fill. The plastic fill tank appear to have a wide lip then the older Mack metal fill tank.   Does anyone know if there's an adapter ?  I looked through the entire Stant catalog  ..nothing  specifically mentioned.

Hello ...1992 MACK RD. Service Brake Lights not working. Tail/ directional / flashers/ and park brake lights are ALL working, hence probably eliminating the chassis wiring and bulbs. I'm thinking possible service brake light switch .....I've located two air pressure switches near steering column. Both when grounded activate low air pressure buzzers, not stop lights. ... Is there a separate service brake light switch? Where would it be located ? ......

Thoughts , suggestions is appreciated
