Follow up question & thanks
Thanks guys for all the input. I was concerned with the fit of other items in the recess, although because I went with the shorter pcu5000x gov, and a remote oil filter setup, I thought I might get away with it. But, in light of the idea of 'gunk' being able to collect on the pressure ports, it's probably not the best location/configuration.
Having said all that, and given that I still need the real estate of the upper left firewall for the oil cooler hose and plenum, any suggestions for a better placement? As background info I have an XP-360, pcu-5000x gov, airwolf remote oil filter, james plenum (and cowl). You can kind of see in the lower right of the pic the mounts for the oil cooler, although the cooler itself is farther down the angles (not installed in the pic.)
I appreciate all the good advice you guys supply on this forum.
