What size vacuum lines come off of that solenoid stock? Mine hd some weird set up. But anyway, the little catch tank has like a 5mm size vacuum line on it, while the solenoid is only a 3mm (sizes could be off by a few mm...).

 

The original setup had a hose that got larger in size. It was flared on one end. I used a 3.5mm silicon hose and it stretched no prob.
