Default Need help with fuel tank setup

I'm new to the boats as well as new to the gas engines. I've got a fuel tank with 4 fittings (fuel pickup, top rear, top center and side center). I saw online that this would be fuel, carb. return, vent and fill. I'm used to nitro where we have two lines, one for fuel and one for pressure. I only have one connection for fuel at the carb. no return, no primer and I have the plate for the pump for pressure.

What is the right way to set this up?

Going by my nitro experience I would think split the pressure to the pump and connect fuel, hook the other two together to close the loop, otherwise how does the engine draw fuel?

I would get rid of the hard tank and go with a fuel bag setup, zippkits.com would have you you need. It would be a closed system so if a boat flips you don't have to worry about water getting into the system. If you have a primmer bulb on your carb, you can take a little of fuel tubbing and blo
ck it off. To start just put your finger over the carb and pull a few small pulls till your finger is wet. Give it a good pull with your finger over the carb, it should try to fire remove your finger and it should start if the engine is in proper running order.

I've seen this on posts, looks like the right thing to do, will get one on order, Thanks for the advice! Tried to post pics of where mines at, won't let me since I'm new here so it's in albums, anyone know what the hull is let me know, it's 54" long.

I would try to get it in front of the motor if possible, zipps also has a video of how to fill the bags, I would get the 27 oz bag, the largest one you have the room.

Hull might be a Dumas scarab, not 100% sure, just was looking at pictures, at first I thought is was an old proboat shock wave 55.

zippkits also sells a nice radio for $20 that has servo mounts and everything, do you plan on running a water pump with the clutch.

You were right, it's a Dumas scarab, they made 2 versions apparently. I've got a water pump but no clutch, I've got the radio box and servos, 1/4 scale for rudder

Sorry it looked like a clutch at first, a water pump without one is not necessary.

Thanks to those that offered help, finances got the best of me and so my poor DUMAS Scarab is on eBay without completion.
