Hi, think I probably should change the filter....currently its a WIX 8144...but cannot find them anywhere....what's the consensus on best solution today ?...thanks
That's a sensible set-up. I'd be tempted to keep all three after the tank is sorted, sort of belt, braces and a wedgie just to be extra sure!.On my 1975 Fairlady z L20 engine I now have a setup with 3 filters and swapping the cheap one regularly as my tank is due a flush.
One inline, straight after the tank (with a ball valve tap between to allow isolation for on the road swaps if required), a clear paper filter before the pump which gets swapped when crud builds up. Then a second paper filter before carbs.
Once tank is flushed, will probably go back to two. A screening filter pre pump and a post fine one.
But still, two inline filters with the same mesh size have no advantage over a single one

Yes sure you need a filter pre pump. My point is that two filters after the pump are pretty much useless
Pressure drop before the pump is much more critical compared to after pump. That is why pre pump filters are usually coarse grid, whereas pre carb filters are much finer (paper style)
