Large and small fuel filter sizes, which is right for an Aircooled engine?

[jjht25]

Hi,

Replaced the fuel filter on my van, noticed that there are two sizes with the large one being the one I replaced for the smaller type. Doesn't seem to be any difference to the vans performance but wondered if there was a 'right' size based on your engine?

It makes no odds on a engine this size , it just means it takes twice as long to fill the filter housing from empty and give a bigger reservoir of caught debris .
i always use the large ones , but carry the small ones in the van in case of issues ( take up less room and fill faster if you are broken down )
