There is no fuel coming from that line, what could be the problem?
-
Does much fuel come out of that line mate?
-
Gday The fuel return comes out under number 4 eup. There is a big line going back to the fuel tank, then there is a 1/4” line come from the front head going back down to the bigger return line. what does this 1/4” line do and is fuel meant to be coming out of it or does it push fuel back up into the head? thanks
-
Thanks mate, I put a new lift pump on it aswell. On the return fuel side of things, the big hose goes back to the tank. the 1/4” hose goes up to the front head, is it also a return or does the return from the block pump fuel up to the head?
-
Thanks for your help mate
-
Ok thanks a lot mate, I’ll have a look at that. Would the regulater be buggered do you think? And could this be the reason it’s blowing a bit of smoke at idle?
-
I just had front cover off to replace camshaft, didn’t see that one. What does the plug do? yes that’s correct, where abouts is the pressure regulator?
-
Hi Firstly Does a old 470 etech usually run a little rough at idle? secondly, changed injectors and o rings, EUP o rings all replaced but engine is still putting fuel into the oil. any ideas or thoughts would be very helpful. thanks
-
Problem fixed, ended up being a brake booster. Thanks for all your help!
-
It’s a big leak, if I don’t step on the foot pedal it’ll leak all air out of the system
-
Nope, it’s been all fine until today
-
I replaced the dash valve 6 months ago, surely it’s not buggered. I can’t work out why when I push in the foot pedal the valve stops leaking?
-
I’ve replaced the valve and it’s still doing it mate. I can’t work it out

gday guys will here 1998 mack trident, i have full air and push my yellow button in and it leakes out of the exhaust part of the rear valve that services the rear boosters. i push the brake peddle in and the leak goes away and air builds up to normal again. i have pulled the service linesof each booster and no air is coming out when maxis are released so boosters are good. any idea where i should start looking now? thankyou will

Front engine mount is new mate, replaced 6 weeks ago. Ok will have a look at them
-
Yep Australian spec, no stored codes at all. How to you fix the front cover flex? It could be that! Where abouts are the green pins?
-
Coolant is the correct level. CHR Mack trident. I can’t work it out
-
Yep the code went away, why would it be de rating itself? When it gets to 29psi the lightning bolt flickers on and off while de rating then go back to flat ground and everything goes back to normal? No boost sensor or ease gate on this engine. Nothing has been done to the engine recently or in fact for the last 12 months other then regular services.

Have a Mack 470 etech engine 1998 model. Boost pressure gets to 200kpa on gauge then starts to de rate itself, does this every time it gets to the 200kpa boost pressure. Throwing a 3-4 code which is engine position sensor, replaced both and still doing it. Just wondering if anyone out there would have any ideas what would be the cause. Thankyou will

No only 1 uni joint on firewall and one uni joint on the steering box
-
Put new cab mounts on, still does it. About an inch clearance
-
2 mounts on the gearbox are good, bolts are tight. Mount on the front of engine near flywheel are tight but still hitting turbo
-
Mack Trident 1998 model 470 etech, turbo touching steering column when accelerating hard under load. Engine and gearbox mounts look ok. anyone with any ideas would be great. Cheers

Have a Mack vision with a v-Mac 3 in it. It’s very sluggish starting, engine turns over very slow then will eventually start. any idea why it would be doing this? Any help would be great. Thanks.
