Since we are on the topic about fuel tanks and capacities, I had a curiousity question about them.......
I have not lifted my fuel tank hatch cover yet (curiousity might get the better of me however). But what I was wondering was, does the fuel filler pipe go to the front portion OR on the rear section of the fuel tank?
Also, if the hatch only lifts so far to gain access to the sender unit, then it would mean the sender unit is towards the rear of the tank and would that not mean that when the boat is in water the "actual" reading on the fuel gauge would be higher then what is physically inside the tank ??
Reason is, my normal fill up for the weekend use consists of a 25L (6-7gal) gas can and siphon pump and from somewhere above 1/4 but below 1/2, the 25L will take my gauge reading to about almost full. So, based on the gauge reading, providing the fuel guage works properly, my tank should be a 50-60L tank... BUT... because of the way the boat sits in water, could my tank in fact be a 70L (16-18gal)?
I don't own a trailer so I can't change the way the boat is orientated (bow towards the ground) to see if in fact you "could" cram more fuel into the tank or not. Yes I know it's not good practice to cram as much fuel as you can into the tank, but more or less knowing if there might be more room in there than I think.

Makes filling up a lot easier and filling up from your dock a lot cleaner as well. A local supplier (Canadian Tire) sells them up here and I picked up the "Maxflo" last week. It delivers fuel around 2 gal or like 7L worth and holds prime till almost bottom. It is a whole helleva lot easier then being in the water and slugging the tank over your shoulder and hoping that you don't spill any onto the transom. From a 2 person job (one to lift and one to guide) it can be done by one person.
Downside, it doesn't get to the very bottom of a 25L tank. But it's simple enough to swap over to the old design nozzle and drain the last bit of fuel into your boat.
$35 canadian, worthwhile investment if you routinely fill up from the road vs marine like I do. Currently it is .92c/L on the road and about $1.22 on water.
