How far do you guys shave down the washer ive heard conflicting evidence????? in other words how much did you shave so i can get a rough estimate? thanks

 

I removed mine and put it in the change jar. No problem.

 

how long ago and could there be bad effects from that????

 

I removed mine well over 100,000 miles ago. Perhaps seven or eight years ago?

I'm unaware of any harm that can be caused by modding or removing the washer. That's not to suggest Cummins put it in there for grins-n-giggles either.

I think (careful), the washer serves as a positive stop for the movement of the fuel pin when under maximum boost conditions. I think it's to help eliminate any sideways loads that may be presented to the needle that rides on the fuel pin.

If you look at a used fuel pin, you can see where the needle rides. Notice that at the deep part of the fuel pin (max boost position), the needle gets close the bottom of the ramp. If one were to shave the washer, one would want to simply remove enough material so as to allow the needle to ride the ramp all the way to the absolute deepest part (for maximum fueling). Any further, would be asking the needle to push sideways against the bottom of the ramp right there. Nothing's to be gained and as you might imagine, with SUPER boost, one could conceivably bend the needle.

Clear as mud?


Take your pick, shave it a little, or just pull it out. I dunno.


NOTE: If you opt to shave your washer, don't get all bent out of shape trying to keep everything ultra flat and such. It's just a bumper in its function.

 

Hmmm, mines in my ash tray. I should throw it away.

 

mine is in the coin holder!

 

To answer your question, shave it by half. Taking it out completely won't hurt either. Your call.

 

thanks guys. i have no pin mods as of this time but in the future it will prolly have to be done. you know black smoke and such also when i can build my trans the possibilities are endless!!!

 

Mines gone too. Don't waste the time on it.

 

even with no fuel pin mods i can remove it right?? i believe that is what everyone is saying. In that case im gonna remove it

 

Dude, are you still running the 4.56 gears with no overdrive th400? you have big cajones if you are. lol

 

I removed the washer and replaced it with a thinner O-ring just to act as a cushion between the 2 parts.

yeah i am running them still the thing rips and its only gonna get more power and an intercooler She does about 72 mph maxxed

 

replaced mine with a coppper banjo gasket.

 

I ran an .070 nylon washer I picked up at Lowe's.
Then I went to an .040.
Now I've got an .020 just as Jim Lane said " to act as a cushion".

Actually, since I've turned up the power screw I'm cranking back on the star wheel and smoke screw and may go back up on the washer.
