If you’re not planning on doing a full-on JohnnyC pro paint job with the fancy automotive paints, try PPG breakthrough. It’s made to adhere to stuff and it’s pretty tough when it dries. I’m not sure how well it would hold up to gasoline, but the PPG people could probably tell you.
Powder coat is also an option if you have the equipment. That stuff is very durable.
I agree with motorhead. Most of this cheap 'fish oil' paint has to be slowly elevated in temperature to outgas those volitiles. A pain in the ass but slowly raising the temp to ~250F over several hours usually hardens it up nicely.
