Hello,

I've just replaced my hydrovac, and am not sure I remember the plumbing correctly

Can anyone confirm that I have the filter and manifold hoses routed correctly? The new red hose is to the filter.

Thanks!

That looks right. Have you started it and checked for vacuum and pedal etc?

No, I'm concerned that it might damage the hydrovac if I have the vacuum on the wrong side.



Thanks,
Joel

 

What is the make and model number of the booster? There are a billion schematics and parts lists on line.

If we have the exact model, we can look at the parts list and determine the atmospheric line, which goes to the cab, vs. the vacuum line going to the intake side of the engine.

Or you could apply a small amount of vacuum using a vacuum cleaner and check the pedal action with vacuum applied. It doesn't take much vacuum to get a reaction with these things.

 

I don't have make and model, but applying vacuum was great advice. Confirmed that the routing in my photo is correct.

Thanks!

 

Glad that worked. Good luck with it!!!
