Hi Mboy,
As long as the fuel line has "enough room to turn" so it doesn't kink.
It looks like you could actually move it more forward to get some clearance as those rod holders are usually just sleeves. So, you should, without looking at it, be able to screw to attach the Racor anywhere in that area, not just crammed in the corner.
I think there is an easy solution (and you will not have to drill into the transom which is always a party bonus in my book.
