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?

I have a SPG with hose and want to use it to check the pressure in a DIN tank, so I need the DIN adapter and a pressure release. (The SPG will be then be dedicated to the this pressure checker.)
 
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.....
