Question Oil Consumption

[JRJ04]

You can see that on my truck.. it's due to the fuel curve of the chip

well, that would make sense, except that i can notice it even with the chip off. its just not as amplified...

then keep your foot off of the go pedal...

Where do you get your fuel pressure gauge? where do you hook it up?

Over Fueling in a diesel is not the same as a gas motor. More fuel = more power. There is no such thing as running too rich, which can cause things like an oily bumper. Wait until you can get some reliable fuel pressures.

And having the FP gauge in the cab, instead of under the hood, could help too. You could be monitoring/comparing, fuel pressure at all throttle demands, verses chip settings. (?)

yep, thats exactly what i did. I've got a 6 foot piece of fuel rated hose so i can feed it through the hood and hold it right by my mirror to watch.

Ever concider mounting it permanently.. In the cab ?

I'll betcha yer guna be wunder'n about fuel pressure now... once you've monitored it... from the mirror... I'll betcha.

Update

Alright, got a new fuel pressure gauge from sumit racing and got it all hooked up...

Same thing again...actually maybe a hair less pressure this time. I couldnt imagine that im blowing off any pressure because I've got no fuel leaking at all. The ONLY thing I'm doing different now vs. when I measured it a year or so ago when I shimmed it, is that im using a 6ft piece of fuel rated hose versus a few inches.

Could this be throwing off my reading?

a hair less in fuel pressure reading from now 6feet from a few inches yes. I would say that's normal. that hose will sure expand a bit. So now my theory is debunked. sorry man hope someone else has a good something you could try.

well i would agree. but a difference of 30-40 lbs? would you agree that it seems off? i guess i need to shorten my hose and try again...but that seems crazy

 

[BIG JOE]

what I.D. size hose is it JR ?
