If it came with paperwork I’ve lost it prior to the install. Can anyone help point me to the right port for the main fuel line on a single tank carbed install? From left to right, there are two threaded ports that were covered with a cap that appeared to be made out of some coating (think like a bottle of makers mark). There’s then the main fill up hose, breather hose, and a fairly small non-thread hole. I THINK the two left ports are for fuel out and return and can be used interchangeably leaving the last unthreaded port on the right for the charcoal system.

Can anyone confirm?

Of the three smaller ports, is one larger? That would be the fuel out fitting.

Does this tank have an internal fuel pump - or one of the ports " piped " to the bottom of the tank ?

Quick question if you just did yours. There’s a blue threaded connector/cap they included that has a center piece that goes in and out. Is this a cap for the other port or some other type of fitting? I have no idea why it would have the portion on the end that goes in and out if so.

Mine did not come the blue csp you mentoned. I had to buy a cap to seal connector 1 and also had to buy a 90 swivel connector for fuel supply coming from the tank.
