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
