From the pump to the poly line you will need a 1/4” male npt x 1/2” barbed fittingand for the 1/2” hose to 5/8 hose you will need a 5/8 x 1/2” barbed coupler
Goggle these things and it should put you in the right direction

The pump outlet assembly should have a low pressure gauge and for pump insurance,,, a pressure relief valve (I prefer an adjustable type that I usually set at 15psi). PRV protects the pump; the most expensive part of the whole system. Air gauge allows you to trouble shoot air flow problems and the PRV is insurance for the pump when there is an air blockage; extra important in freezing temps. When trouble occurs in the aeration system, the 1st question I ask is what is the reading on the air gauge. For rotary vanes, they do not tolerate psi over 30psi and then the vanes snap.

FYI a 3/8" threaded nipple can serve as a 5/8" hose barb because the OD of a 3/8" nipple is 5/8".
