If the hose is at the top of the engine, you could probably part the van
pointing nose down (a little slope - just enough to put the top of the
radiator below the engine) and get away with changing it without much
coolant loss.
However, I think the plastic part it is connected to is the bleeder valve:

and
these are notoriously brittle after 30 years. I'm surprised to see the
plastic one back in stock - I had to replace mine with an aluminium one
that cost nearly $200.
So, if you do replace the hose, be careful with the plastic parts. The
bleeder screw especially.
If this were me, I would probably leave the hose as-is. If you were going
to replace all the coolant hoses/pipes, sure, go for it, but I don't think
I would go at it unless it was causing a problem. But Denis knows more
than me about these things - so now I'm wondering why using gas line would
be bad?
