Chris,

I'm definitely interested *if*:

        - It can be done to a new tank. I don't want to replace one rusty old tank
with another rusty old tank... and I want to keep my existing tank on-hand
in case there are unanticipated problems (I know... it's so simple, what
could *possibly* go wrong? ;-)

        - It can be done for considerably less than the $550.00 the existing
larger tank costs.

        - The modified tank can bolt up without modifying the van (I believe the
existing hi-capacity tank requires a frame modification).

I replaced my rusted-out power steering lines with Frank Condelli's
hydraulic hose kit, these run alongside the heater hoses... it sounds like
you left enough space for that, am I correct?
