Ok, sounds like I need to replace that fuel filter. Where is that bad boy located at? Is it hard to change? Thanks for any and all replys.
The 3500 and 2500HD have the same hp rating with the allison. You don't have to run an additive, but if you want, stanadyne and racor is the only "approved" additive for the fuel. You can use power service additive too. I have in the past when I couldn't get stanadyne.Thank you! I just checked and it's a D. Yes I have the owners manuel. Looks like I should also be running an attitive in my fuel. What's the best stuff to run? Oh yea, what is the difference between the two motors? I heard the 3500 has 20 more HP is that true? Sorry for all the questions. Thanks
Be sure to buy it from an Allison dealer and not GM. GM wants $35-$45, You can get it from an Allison dealer for about $10.Great info and tips!! Thank you bros. The tranny filter I am assuming it's the small red one on the bottom of the trans?
