Don't crucify me. Have no info LOL. Replacing a pump and cap tube in the morning. True box, Tecumseh 1/2 hp 134a pump. Pump is rated for high temp, application is med temp. I think it was a BC4 cap tube I picked up. Cap tube length should match med temp, not high temp correct? There is something like 40" difference in length. Truck is in a storage lot and I forgot to bring my notebook home.
