With each vacuum pump there is a set of instructions that say "clean the tubing so no debris will enter a gage". My question is this: If a vacuum pump draws air FROM the canister air filter, through the instruments and vacuum gage AND pumps the exhaust air out the pump through the rear tube ... HOW does derbies manage to go the REVERSE direction from the pump back to the instruments?

Every time we put it back in we have a problem getting the screws into the tinnermans that tend to move out of line with the holes. Is there any problem with replacing the tinnermans with rivnuts and using machine screws to attach the glareshield? Scott Boyce, AA5B, N28339 tscott165@cableone.net
