nismoman18 Posted June 15, 2003 Share Posted June 15, 2003 i changed the fuel filter with the fuse in and its only bad cos the fuel sprays all over ur face! but other then that i dont think its a worry Link to comment https://www.sau.com.au/forums/topic/18294-how-to-deprussurise-the-fuel-system-eg-wheres-the-fuel-filter-fuse/#findComment-382215 Share on other sites More sharing options...
fade Posted June 15, 2003 Share Posted June 15, 2003 If the ignition is not switched on I cannot see how the system is pressurized. The fuel pump must be working to do this. When changing the fuel filter, I suggest disconnecting the battery just to be safe. It is also wise to do it when there is not much fuel in your tank.

nismoman18 Posted June 15, 2003 Share Posted June 15, 2003 well you could do that man but next time im just gonna get a bucket under the hose or crimp them Link to comment https://www.sau.com.au/forums/topic/18294-how-to-deprussurise-the-fuel-system-eg-wheres-the-fuel-filter-fuse/#findComment-382562 Share on other sites More sharing options...
predator Posted June 15, 2003 Share Posted June 15, 2003 i wouldn't stress too much.. i jsut pulled the hoses off, a bit of petrol sprayed places (which i later cleaned).. and clamped it back up.. Ran the car for a minute or so just idling, and it repressurises itself basically.

skyr33 Posted June 15, 2003 Share Posted June 15, 2003 Find the fuse for the fuel pump and pull it out while the engine is running.The engine will consume the fuel within the system and eventually stall.Crank it over a few more times just in case.Thats all.

ScarifieR Posted June 15, 2003 Author Share Posted June 15, 2003 yeah and where is that fuse! Link to comment https://www.sau.com.au/forums/topic/18294-how-to-deprussurise-the-fuel-system-eg-wheres-the-fuel-filter-fuse/#findComment-383154 Share on other sites More sharing options...
JimX Posted June 16, 2003 Share Posted June 16, 2003 Whenever I change the fuel filter I just let the car sit overnight. ie, get home Friday night, then change the filter next morning or afternoon. There's never any pressure in the line, I just put a towel underneath to catch the stuff that drips out.

fade Posted June 16, 2003 Share Posted June 16, 2003 Exactly JimX. I should have said that I let it sit overnight, but I also do this because I don't want petrol spilling over a hot engine Link to comment https://www.sau.com.au/forums/topic/18294-how-to-deprussurise-the-fuel-system-eg-wheres-the-fuel-filter-fuse/#findComment-384492 Share on other sites More sharing options...
JimX Posted June 16, 2003 Share Posted June 16, 2003 Don't be too worried about a hot engine igniting the petrol, it's actually a lot harder to ignite than you think. Especially premium fuel. I work on a cold (or moderately warm) engine for my own safety, I've had more than enough burns due to a hot engine to learn my lesson.
