Want to change fittings on propane

Last season I let the tank go dry and want to pull it and replace everything. Sand and paint while I have it out.

Any recommendations for places to buy parts besides camping world?

Let it go dry.......empty propane tank is NOT an issue


Sand/painting can be done in place......
Paint it white/silver/light grey (paint restrictions)


But if you really want to spend money

Check with a local propane supplier that does install of tanks for houses. If you have the old fittings in hand then you can match them up for the new.

Don't forget.......once you have removed/replaced fill valve, sensor (gauge) and relief valve (should be replaced due to age) you will need to have tank 'purged' as you have introduced air into the open tank

Purging can be done by vendor....they fill/release VAPOR 4x-5x to get rid of the air
Then fill with liquid propane

If not purged.....air entrained with the propane can cause popping, flow, ignition issues

Nearly complete but new level sender arriving tomorrow and bought the wrong fill valve. When I removed it had opd float that I didn't know about.

Thanks for purge recommendation. I didn't know about it but had noticed it today while searching about opd device and whether I really needed it.

All propane tanks/cylinders have been required to have OPD since 1998

Tank looks good.....nice paint job

If replacing the Fill Valve and Level Sender you should also replace the Relief Valve (recommended if older then 10Yrs)

The fill valve and on/off valve were leaky. My relief never had an issue and I thought it was just a manual valve they use during fill and manually shut. Are you saying this can fail?

Am I thinking of the correct part? Where is the relief valve you mention?

Not sure if this is an issue with propane, but the fittings on Natural gas require a special teflon tape (if you're using tape to seal the valves). It's available at big box stores or your local hardware store.(it's yellow)

That would be the Fix Liquid Level Gauge---known as Bleeder Valve (Outage Valve in diagram below)
Crack it open when fill...propane vapor comes out until liquid level reaches the 80% Capacity then will spew some liquid propane out
Fixed open ended pipe at the 80% level which s FULL
**OPD is also set for 80% capacity but should NOT be relied upon to stop filling process

Relief Valve is on the bottom of tank so if it OPENS it spews propane vapor downward into open air
Has a Fixed Open ended pipe that extends up into vapor area
Should be under that protective 'shelf'

*check the rating on it....they come with different springs for different relief pressure settings

The valves came with blue sealant. I was going to use teflon tape but could only get a couple of turns before it was too tight. Using the blue sealant on valve I could get many more turns on it. The old valves used the blue sealant preinstalled also.

UV436AR relief valve
312.5 PSI 3/4"

Seems like no such part anymore. Are people using lower pressure relief valves now?
