Tanks ittt bery helpfully

Thank you for your help, it help me a lot your advise.

I removed the regulator valve today. It was very difficult to get to. I found the best way to get to it was by removing the shifter. Then using a 13mm shallow socket with a wobbly 6inch extension.

Sorry I don't think I saw this.

Hey any idea why I can only get 20-23psi boost when it gets under 15 degrees outside and as soon as it is 15 or above it boost normal 30-32psi.

I think maybe your fuel is jelling and restricting your filters

I appreciate the schematic, that definitely will help, I will go see that truck tomorrow, and hopefully one of those turn out to be faulty. Thanks @damon bramel

Daf has mx, fuel filter module has valve built in,, need to replace it, complete.

Hi, do you know where is fuel low pressure regulator on MX11 engine. I replace the lift pump but still have only 2 bars ☹️. Thank You

I'm not sure on mx11. But I think places you can loose pressure are at the lift pumps and the regulator on the high pressure pumps

What was the fix to this mx that only has 3 psi on low side fuel pressure?

@monray300 Darn, I got one that's doing the same thing as described in your video.

Can you post a picture off the diagram please

I have black smoke. Could this be the issue?

I guess it could, if you have a dpf it shouldn't. What else does it do?

My MX13 misfires after hitting around 40-50 mph only when you let go of the gas pedal and hit another gear. Kinda like it’s starved for fuel but if you stay in the gear and don’t let off gas it’s fine. It also does it when I go to downshift up hill but if I don’t let off the gas pedal completely it won’t do it. Any ideas?

Is your fuel contaminated? Sometimes they put the wrong fuel filters in, if they don't use the vin number, but it's unlikely 3 dealers would. Is it restricted or sucking air? Request they change filters by vin number. I know Missoula Montana Peterbilt has 4 good paccar mechanics.
