Mate, I think you may be just looking for a argument, simple as that. What you said and I will quote " If you always keep your tank full, lots of junk from the fuel can settle in the sump because its never getting close to empty, then the first time you have to drive until its near empty, that's when all of the garbage hits your fuel filter all at once ".
Thats incorrect and illogical . Don't you think that when you drive around and the fuel moves in the tank that the contamination will mix with the fuel and then get sucked up by the pump pickup whether its full, half full or near empty?
As far the location of the pump pickup being not directly at the bottom, fair enough but it is very close to the bottom for obvious reasons.
Ford Pinto, I've read the story before. Can't see the relevance.
As for the maths, I have no interest in calculating exactly how much condensation may form. How could it possibly be accurate?, and of what use?.
Fact, under the right conditions condensation forms in fuel tanks. The lower the fuel level the more condensation that can form. If you want to calculated it, go for it.
Is it enough to cause problems?, well in common rail diesel engines it can cause injector failure where the tips are blown off and damage to the high pressure pump. Gasoline injection?, runs significantly lower pressures but I would prefer not to find out.
Once water enters fuel it forms in 3 ways, Free state, Emulsified and Semiabsorbed. Its the semiabsorbed that can do the real damage to the fuel system.
What pissed me off was the fact you simply dismissed the idea that condensation could be create real problems when you have No first hand experience with the issue. Google will only get you so far.
There was no name calling, I gave a rather harsh option of the first part of your post and laughed at the idea of trying to calculate the amount of condensation that may form in certain conditions ,a little unkind so I apologise for the Lmao part, but I have seen first hand the damage water in fuel can do.
