Jim is correct about NFPA. According to a NFPA 58 fact sheet at
http://www.nfpa.org/PDF/OPDFactSheet.pdf , "...The 2001 edition of NFPA added
an exemption for horizontal cylinders manufactured before October 1, 1998 do
not need an OPD, and can be continued in use..."

I am looking for an Auto Stop fill valve repair or replacement and recently
recieved the following answer to my query from Diane Hickey at Manchester Tank:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
..It is acutally against the NFPA 58 to replace an old
Auto Stop valve with the new 80% stop fills.

 If your Auto Stop is leaking around the weep hole or you can't push the reset
button we have an O-Ring kit that should solve the problem.  The O-Ring kit is
our part number V20128.  You can order it through Camping World or a major
propane company.

Thanks

I could not find said O-Ring kit at Camping World or anywhere else. Mine has
begun blowing back propane for a minute or so after filling -- most alarming.
Can anyone on the list tell me where to mail-order a replacement manual fill
valve that will fit my 87 westy?

TIA.
