2000 OBS 6.5TD Fuel tank pressurizing.

Let me do some out loud thinking here.

Is it possible that while the tank is negatively pressurized, that once the truck is shut off that is could drain the fuel out of the injection pump and fuel lines?

Not unless you have a hole in your line. The vacuum is pulling on both lines equally.

And regardless of what happens in the line, it cannot affect the IP, as it's on the other side of the fuel solenoid.
 
A 6.2 that does 85 mph ?...:eek:..must have been going down hill--a STEEP hill!......:thinking:...

I've had my pickup up to 80 once...not something I'd want to try again...tires felt square after 70..sounded like it was still in second gear too.
 
Not a good idea to leave the diesel dash in place after a gas engine swap..
I know someone who put a 350 in place of a 6.2 in a pickup like mine--and left the dash intact...
One day a friend borrowed his truck to move some furniture,and thought he'd be nice and top off the tank--with diesel!..

Not long after that his wife was driving it one day,and the "water in fuel" light came on...so she did what she thought was right...yup..
--she added water to the gas tank!..:doah:.."but honey--it SAID it needed water in the fuel "...
 
Hard to say where @campy pulled that pic from.

From my trip to dune fest last summer. I-75, lower Michigan. It was flat and that was the speed of traffic. It stayed above 80 for a couple hours. The truck is happier at 80 than it is at 55. Optimal cruise is probably 70 or so.


Yes, it's still a factory 6.2 engine, and, yes, it takes it's sweet time getting there.
