Coolant Leak on 98 Crown Vic

[hoofnit]

Yes this is specifically CNG related as I have a small coolant leak at the heat exchanger (?) back by the filter and shut-off switch. I can't identify which fitting may be leaking, nor do I understand why I am heating (cooling) the gas before it gets to the engine.

Any experience on this out there?

Could this possible be the regulator and in most cases the coolant is ran thru it to keep it from freezing up

If it has the plastic bowl, it might be an "O" ring. It's more likely than if it has the metal bowl as some of the conoflo regulators have.
