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.

hello, I had a problem in the second section of the high pressure pump, I changed the plunger inside and the valve was jammed, now my question is with the cups is everything okay? what do you think?

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

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

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.

Tanks ittt bery helpfully

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.

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?

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
