MEP 803a fuel filter housing (spin on)

Here are a couple fuel filter heads that might work:

Donaldson P560382 - has 1/4 NPT inlet & outlet
Donaldson P562263 - has 1/2-20 UN inlet & outlet (works with o-ring boss)

Both of those heads have M16x1.5 threads for the stock primary fuel filter.

I've used these heads on my auxiliary fuel tanks and can confirm that they will share the same spin-on fuel filter as the 802 and 803.

If i had to replace the filter housing i would be useing a raycor style filter with a clear lower section. Easier to keep an eye of fuel quality.

Yeah I've just swapped the unit out with a WIX replacement before (with bottom drain), but on my personal machine thats what I would probably do.. just upgrade to a bottle style.
