Unfortunately, my projects aren't so interesting as my boat is 500 miles away from me. So I've been relegated to projects around the house...
KY, just a quick note... "technically" the location of your battery is against the USCG regs since it's below a fuel fitting. I know you probably don't really have space to move things, but maybe some type of plastic diverter setup under the filter, fittings and sensor... I'd have to think more about a logical solution, but just throwing that out there as "food for thought".
On a more interesting note, an easy upgrade is to install a vacuum gauge on the unused "output" of the filter head. Given the location, you may have to use some fittings to get the gauge to readable position. But it can easily tell you if there's a restriction somewhere between it and the tank/vent. You can also use it to monitor the condition of the filter. Truthfully, the only reason we change the filter every year is because we don't know it's condition. Yeah, it's not expensive so no big deal, but it's also wasteful. Besides, every dollar counts, right? I haven't changed my filter in 4 years. As long as the gauge keeps showing the same thing, there's really no reason to change the filter.
Ideally, you'd get a gauge with, say, only a 15psi dial (or even a bit less, still) - but this is the one I used:
