Fuel filters, in line or parallel?

[vic008]

Have 2 diesel tanks, 2 identical racor filters, 27hp engine. Best have filters in line or parallel?
Fuel here seems pretty trouble free

Parallel with manifolding that enables changing between filters on the go.

like above post said, parallel, here is a pic

You may find another filter on the engine as well.

I can think of only 1 reason for putting filters in-line:
- to have 2 different that filter to ie 30 micron for the first filter and to 5 micron on the second one
I can think of only 1 reason to have 2 parallel and fixed and this likely does not apply to you with a small engine:
- the max flow rate of diesel can not be handled by one filter, so one would need 2 or more filters parallel.

Or in your case, is there a fuelfilter for each tank?
