fuel tank venting w/perry regulated pump

[Bob Richards]

Muffler pressure worked well on a pumped OS 1.20 about
10 years ago. A freind was having a problem that was
hard to diagnose, and just on a whim we hooked up
muffler pressure. Got through a contest without any
problem. Later, we found we had a small air leak in
the system, running the muffler pressure helped. As
far as that setup went, muffler pressure worked ok.
