    Funny you posted this. I am, as we speak, installing a tu- flo 750 on my 87 E9 Superliner. Call Bendix with your service number and they will cross it to a 750. What sucks is that they will not accept your core. Mine set me back 1200. The truck is a heavy wrecker, and I need the added volume as sometimes I have to air up a damaged truck or trailer. Good luck- Marty
