ballast tubing size

[Jon]

I'm customizing my ballast in my '01 Mobius. I was wondering if anybody knew the tube diameter for the stock ballast. I think its 1 inch but i'm not sure. Can anybody confirm the for me?

The hose diameter is 1 inch, the pump outlet is a little bigger, so you may have to heat that end of the hose with a heat gun and put on the pump while warm to have a good fit.Brian Raymond

For anybody else wanting to know, the "in" tubing is 1" ID, not sure what the OD is. and the "out" is 3/4" OD, probably 1/2" ID. found that out after I bought all one size tubing and nothing match with PVC connectors.
