    Look closely at the pressure switch fitting where the hose connects. Do you see a small hole, about the same diameter as a paper clip? If so, try wrapping a piece of tape around the fitting to block the hole. If this works, either the switch diaphragm canister or the inducer housing may have a leak. This is just a quick fix until the real problem can be corrected. I would not recommend bypassing the switch, even on a short-term basis.
