I want to put in a mallory 140 comp pump and regulator but the marine version seems to be unavailable...? Anyone know where I can buy it or if i can just use the standard non marine 140 pump? What is the difference between the marine and standard pump? Or if there is another pump i could use? Seems like the 140 is my best choice

Mallory doesnt make the marine version anymore... but they said there was no difference, just talked to them. So i will just use the non marine one. I guess they never bothered to get it recertified.
