, reasoning is of course a leak would spray fuel, as opposed to a line under vacuum, would just leak air into the line.
To operate without a pressurized fuel line, my Mercury
Verado had something similar to a toilet bowl tank on it's back, a low pressure pump would keep the tank filled, with turn on and turn off switches it maintained the fuel level, then there was a high pressure fuel injection pump in this tank that ran the fuel injection system, this Rube Goldberg contraption was required because you not allowed to have a pressurized fuel line inside of the hull
, simplest thing would be like all automobiles, just put the high pressure pump inside of the fuel tank
From a safety
perspective, it makes sense.
I have the Dual Racor set up, if my engine starts to sag, I jump down there and flip the valve over to the other filter.
I understand what the electric pump
is for, my IP came with one from the factory, it no longer works, and I couldn't find a replacement, and honestly if you understand how the manual pump works, it only takes about 1 min. to fill both the Racor and the secondary fuel filter
. I don't think I need the priming pump, but then again I have excellent engine access, I sit on a seat cushion placed on the sole and have much better engine access than any automobile I have ever owned, if access wasn't so good, then I may have a different opinion on the need of a priming pump.
