Now a fuel distribution question.

[Litton]

On my incoming fuel line, there is a "valve" with a hex head adjustment bolt on the top.....then the fuel line comes out of this unit to another one (also with an adjustment on the top) and goes out to the two fuel distribution lines.

I would suspect that the first unit is a pressure regulator and the second one is an adjustment for distributing the fuel. Am I close?

tks in advance

They are pressure damnpeners and regulators. I haven't touched either one, personally - I don't know if they're meant to be touched (LP gas grills have adjustable regulators but I know nobody willing to fool with them!)
