When I put both black levers to the right, I can hear the fresh air fan blowing but the airflow out the defrost and dash vents is quite minimal. The fan does work on all 3 speeds.
Similarly -- I just reattached all my heat, and even with the booster fan going in the engine compartment, there is just not much airflow. The engine compartment hose and the flapper --> firewall hose are new, the HX's are SSIs in good shape as is the rest of the engine compartment plumbing. What level of airflow should I expect? What should i check or refurbish to get better CFMs? |

Rich, the McMaster link you provided is for a 5/16" od tube. That won't work too well.
AFAIK McMaster has only one product that's suitable to replace those 60mm id paper tubes. I bought some "Blo-R-Vac" rubber hose from them in the past that works good. Its almost $4/ft. though. |
