1989 311 sr1 thunder & silent choice
Hi guys, I have recently purchased a 89 311 SR1 with thunder exhaust and silent choice. Any ways, my air pump for the silent choice is pooched. Its a Thomas pneumatic pump model 315CDC40/12-175C The manufacture told me they were also installed in the automotive industry too but stopped short of telling me what specific models and years.I can buy the new updated pump but I wanted to try and find a good used one. Anybody have any idea.

I know you have a specific question but Stock silent thunder isn't very loud. It's not much louder than through prop.
