Hi...

Big problem... My bro's car is drinking an enormous amount of fuel....

lets just say 15 litres of fuel is gettin him about 40km's.. and thats with very light throttle.

no theres no obvious fuel leaks on the tank or on the lines and the exhaust is not smoking as to say its running rich....

i doubt the O2 would would have to do anyhting with it.... or the fuel filter...

but where else should i be lookin for a obvious leak?? i doubt the engine could be sucking that much fuel... its gotta be a leak but from where???
:bang:

oh yeah is there a AFM on VN's?? where is the fruk is it??

my car was using 100L/100km once, check your rockers, (remove rocker covers) one of my rockers was bascially unbolted and i was running on 5 pretty much wasnt opening a valve... maybe also a leak in your inlet manifold, can u smell any fuel??? check that your injectors are sitting in properly because that is serious fuel wastage, its like 35L/100km???

exhaust smell isnt rich.. doesnt miss

but yeah cant hurt to replace the fuel filter,... actually yes it can u get petrol in your eyes!!!!!!!!!!!!!!!!! but its worth it

willl change it if all else fails.... its called depressurizing the system before u flong the hose off... :thumbsup: I learnt the hard way....

Check what pressure your fuel regulator is at, or just renew it

Check you air filter, sparkplugs are gapped correctly, vacuum leaks, faulty coolant sensor, faulty thermostat and lastly the MAT and MAP sensors.

follow the fuel lines from the pump right up to the engine you might have a pin hole in the fuel pipes.
