Replacement Valve for AirHog Guppy Tank

[prjagman]

Posting for a friend that it’s currently overseas and needs a replacement valve for his 10+ years old AirHog guppy tank. His valve suffered some type of non-repairable internal failure. Went to the AirHog page but it didn’t have any info. Emailed them an inquiry, but wanted to ask the Airgun Nation community if there are other sources or options for a replacement one.
Thanks.

Ask your buddy to remove the vale and measure the diameter. (Most likely to require M18 or 7/8, is my guess)
