Where and in which manual will I find information Treadlevac for my 54 twin H Hornet.
I believe I'm losing vacuum but not sure how it's suppose to be plumbed, check valve location or what vac reading to expect..
Is the fuel pump vacuum pump necessary for the power brake to work correctly?
Also have disk brakes on front..
Dave, I believe it is in the '53 -'54 supplement manual?.
Where can I get a 53-54 supplement manual? I found a good description of the Treadle Vac itself in the 55 Hudson manual. but it didn't mention the tank or where the check valves were in the vacuum circuit.
It would seem obvious that there should be a one way check valve between the tank and intake manifold, but what does it look like? Is it in the tank?
On my 54 I found a 1way valve between the tank and the treadle Vac, this doesn't seem right but I'm not sure what is.
Thanks
Dave
