I've had good luck with Earl's fuel supply components. The nice thing about Earl's is they are aluminum, anodized and have smooth retention for the hose clamp. However, a well placed and tightened hose clamp is a must for these.
This allows you to pull the hose off without damage, unlike those vicious barb connectors that typically need to be cut off. Removing the hose off a typical barb connectors risks shredding and putting fuel line bits in the carb.Thanks,

This one:
Sadly the chrome is not salt-water rated, it looks a little beat now. The gauge works fine still.
You need a 5 volt 5 PSI transducer, which they seem out of right now.
Randomly looking around FleaBay I found this example:

Strongly recommend one with a glass lens. Avoid a plastic lens - a drip of gas will mar the lens.
Also, mine was hard mounted to the carb. Made it tough to change carbs as I also had to switch the gauge.
The comment about barbed fittings shredding the hose is good. Just use an 1/8" NPT nipple and cut the threads off one end. Hose to fit (I think 3/8 goes nicely).
