Background:
I have a QB 8, and am planning on putting an EFII (FlyEFII) system in, so I will be routing return lines to the tanks.
I am about to finish the tank access plate, and so I have read up about the two types of pickup tubes. Built per plans (aka Slotted) and Vans pre-made w/Filter screens. In my QB kit, the slotted pickups were already finished for me, but not yet installed.
With the EFII system, there is an optional 100 micron pre-filter before the pump, and a 10 micron filter after the pump. The fuel goes through both, before being used or returned to the tank.
So now my questions:
1) Is their any reason to "upgrade" to the screen pickups, vs. the slotted ones I already have? I get that the screens will filter out more particulates, but it is a non-serviceable screen, being sealed inside the tank.
2) I pretty sure the optional pre-filter would be in the cockpit on an 8. How do people clean those filters, without messing up the interior?
3) Has anyone done any alternatives to putting the pre-filter in the cockpit, or is that even possible?
4) Is it ok to skip the pre-filter, given that it is optional? What is the down side to that? Would that be a dumb move, or just a builder preference? Or maybe only skip this if the pickups have screens on them?
