Strange Fluid in Propane Lines???

[Handy1]

Decided to change LPG regulator on pup from the standard issue to a automatic change over regulator. Upon removing the main line connection (trailer side) at the regulator, a strange fluid began to drip out of the connection. It was a rather small amount of fluid, just curious as to what it may be. It was somewhat oily. Is this just a combination of the LPG and condensation from use??? We live in the S. Louisiana where the humidity is always high.


Thanks

My guess, with some LP knowledge, it is just that - condensation.

Was it dripping from between the regulator and the tank, or from between the regulator and the PUP?  Under certain circumstances, it is possible to get liquid propane in the lines between the tank and the regulator, but that usually boils very quickly when the regulator is removed (or the tank is shut off for a few minutes).  In most areas, LP is actually a mix of mostly propane with some butane, and the butane has a higher boiling point that might allow it to collect.  Still, I would expect it to all boil/evaporate (even still in the hoses) within a minute of the pressure being removed.

Otherwise, probably just condensation.

Handy,

don't know what kind of PUP you have, but on some models, you can't use an auto changeover regulator because of the combination of high pressure and low pressure services.  on our bayside, we have a high pressure stove outside and a low pressure on inside.  we don't have a furnace so I don't know what pressure that uses.  either way, I don't think the autochange over regs are two stage regulators that will accomodate both types.  

If you do have both high and low pressure and it works, please let me know because I'd love to use one if I can

Travis,

Wish I could help with this one..... But my Pup is a 2005 Fleetwood Newport that only use low pressure LPG. That is why I elected to go with the auto change over style of regulator.

You may check with Marshall LPG regulators and see if they off a high/low pressure auto change over regulator.

The only other option I see is if you use a "Y" in your tank line before the auto change over regulator. One line would go to your High pressure regulator and the other to the low pressure auto change over regulator.

Any appliance that is designed to be used inside is low pressure.
