Fuel line size

[Bob Bradley]

Can someone tell me the size of the fuel line from the tank to the primary Racors on a 79 37C? It's 90 minutes away from home and I need to order a couple of fittings.

On my '78 37c I have 1/2" supply and 1/2" return lines.Mine was repowered by the prior owner and I don't know if the fuel lines were upsized at that point though. The fuel manifold is original to the boat and has 1/2" valves; this leads me to believe 1/2" fuel line is likely original.MattI will be replacing
