    Default Fuel filter options

    I'd like to get away from the CAV filter and fiddly O rings on our Centaur. I've got a beta 20 to go in. I understand that the Racor turbine filters are too big for such a small engine (presumably need a minimum flow for the centrifugal magic to happen?). They now offer a smaller clip-on version for small boats, but the replacement filters are ovet £30 a pop.
    Is there a middle ground - something less fiddly than the CAV but not as expensive as the Racor?
    Thanks

    I went for Separ when replacing my CAV filter. It is rated at 5l a min.

    Filters are expensive but far less expensive than my time trying to get a CAV filter from not leaking.

    I still think the Racor is the way to go.

    I've just looked at Separ. If I've found the right one it makes Racor look like the budget option! It's early days yet in the engine department.

    Yes, you can get a CAV-type filter head which takes a simple spin-on filter. About £23 - https://www.ssldieselparts.co.uk/fil...a11-p-718.html

    The 496A spin-on filter is about £6 and, incidentally, it has a drain screw.

    You could go for a Racor as your primary filter (does not have to be a turbine - Racor 120 or 320 are suitable) and then the spin on CAV-type, as described by PVB, as your secondary.

    Doesn't the Beta 20 have a secondary filter mounted on it? Why have 2 primary filters?

    My mistake - I was thinking that the CAV was fitted as a secondary. The main point holds though - you could use a Racor spin on filter (as opposed to a turbine), but I accept that the spin-on CAV type are cheaper.

    Buying second hand is a cheaper option.

    Buying used fuel filters ?
    Seriously if going down the CAV spin-off route check if SAE or metric

    Why? The ports are UNF, the filter's metric (although it doesn't really matter what it is as 496A filters are standard).
