    Any suggestions on how to use a spare SPG (with hose) to make a DIN tank fill guage?

    Are you asking for a pressure checker? Or how to add a traditional SPG in line on a fill whip?

    For $39 you'll be better served with the DGX tank checker. Unless you have a spare reg laying around it will cost more to make your own than to just buy one.

    Just take old dead or near-dead (or just unused) 1st stage. Close all ports with plugs. last HP potr attach to yours SPG hose. One LP plug stay without o-ring.
    Bingo!
    Attach to the tank. Check pressure. Wait a little, until pressure will drain over absent o-ring. Detach from the tank.

    Having a proper pressure checker isn't critical, I used a regulator set for about 5 years. Now that I have one, it's almost luxuriously easy to check my tanks. I guess the value of it depends in part on how many tanks you own.

    Mine is similar to that dgx pressure checker, although I'm pretty sure I paid more for it.

    My DIY pressure checker is complete based on SB member input. Thanks!!

    Not to complicated.... a LDS donated defunct 1st stage, a like new SPG and hose found on “Marketplace” and a fabricated LP pressure release valve. My DIY valve stated off being a hex head bolt and hex head nut..... add a little forge work, filing/grinding, epoxied assembly & paint... done. Works well!

    Total Cost: $20. Labor: don’t ask

    Now all I need is a good/safe place to go diving.....
