Heck even my 98's WIF sensor went off when it had a 1/4 teaspoon of water in the filter housing. It was left over from the 30 gallons of water I pumped into my truck one morning. :M
So water get's into the fuel and then there is rust??? What the heck from???
I'm not talking about the old fuel systems. Even a 7.3PSD can engulf sand and water and not phase the injectors.
Think about the precision that the injectors have to be machined to hold 20k+ psi of fuel pressure on them without leaking, and then think about these precision surfaces with just a flake of rust that prevents them from seating properly. It doesn't take much and is the reason Ram went with a dual filter system like Ford.
A true water separator won't let water through. I never understood people saying the dealer told them rust was in the system. IDK, could be but not likely. My thoughts are that the filter stops the water and fuel to the pump. The pump that GM and Ford uses grenades when starved.
I still haven't really figured out why the V8s are having to run such high fuel pressures to make the same power as the 6. It takes so much fuel to make so much power. maybe someone could school me on this? I would think the volume of fuel it can put out at the required pressure would be the thing.
6.0 injectors are the same way. Run a 6.0 out of fuel and you just as well order some injectors.
It has nothing to do with a V8. Diesel fuel is difficult to atomize and atomized fuel burns cleaner with less soot and less soot means a more reliable emissions system. Hence the reason for the increase fuel injection pressure.
The 2.8 I4 Duramax in the Colorado runs 29k psi and its a inline engine.
More reliable emission system or more reliable injection system..........hhmmmm I'll take the injection system Jim! lol
Again the fuel system failures are very rare, but the emissions problems are very common.
I would say guy would disagree with you!
LinkIn the Chevy thread your considering a Ecodiesel with a CP4. I can't tell if your coming or going.
