I bought this truck broken and I don't know any of its history other than it has a blown head gasket.
I've tried to be diligent about labeling things and it's possible I labeled this but the tape fell off. It seems a little rough on the end and I'm a little worried it got snapped off? But I imagine if someone snapped it it would be more jagged.
Either way I don't think I removed the hose that goes to it and I'm not sure where that hose would go.
