The Lion Cubs were quickest out the starting blocks and on two minutes Cleall fired home from a cleared corner.
The second came in the 20th minute when a good run from Irish found Stanley, who slotted home.
In the 33rd minute, Jake Greenslade arrived at the far post to knock in the third goal. Ferring came to life but on the break Ceri Marsh found the fourth.
Pressure from a Pagham corner led to an unluckly defender putting through his own goal. Rogerson slotted home number six then Selby helped himself to numbers seven and eight.
This win puts Pagham top of the west-division table.
