my day tank to a deck
fill. As "convenient" as it would be to run the low pressure fuel pump
(I even could have plumbed the line when I had the fuel tank
open the other day), one nice thing about the deck
fill that works for me is that I can burn off iffy diesel
with it. Not absolutely bad diesel, but diesel I wouldn't put into the racors and yanmar
Here's a 1 1/2" reducer bell fitting for anyone interested:

You need to drill a vent hole for the day tank anyway so no matter how you slice it (no pun intended) it's either one hole (the vent) or two (vent and deck fill). Considering that a day tank is around 5 gallons and they burn ~1 gallon a day you would have to run the heater a lot
in order for deck filling to get annoying.
But different strokes for different folks; if I was an engine/systems guy I could totally see the low pressure pump
thing making a lot of sense. I'm sure the first time I need to deckfill in the rain I'll appreciate the idea of flipping a switch to refill.
