Steve Posted February 18, 2006 Share Posted February 18, 2006 Gonna change my fuel filter on my Supe. Is it a good idea to run the car, disconnect the fuel pump power and let it stall so it reduces the fuel pipe pressure? Thanks Link to comment Share on other sites More sharing options...
merckx Posted February 18, 2006 Share Posted February 18, 2006 Just had a look at my new manual. Disconnect the fuel pump connector, it's near the spare wheel (front/left corner). Then start the engine and run until it stops. Link to comment Share on other sites More sharing options...

Angarak Posted February 19, 2006 Share Posted February 19, 2006 How often should a fuel filter be changed? I have a 95 J-Spec TT, and was thinking of changing it. Link to comment Share on other sites More sharing options...
letmeshowyou Posted February 19, 2006 Share Posted February 19, 2006 surely it would be easier to take the fuel injection fuses out than undo all those bolts to unplug that connector at the rear? Does the manual really say to do that :S Link to comment Share on other sites More sharing options...
Steve Posted February 19, 2006 Author Share Posted February 19, 2006 The plug only sits in the spare wheel area. Nice and easy Link to comment Share on other sites More sharing options...
letmeshowyou Posted February 19, 2006 Share Posted February 19, 2006 it sits in the spare wheel area... under a cover which is bolted on. There are 6nuts to undo. see my pics here: http://www.mkivsupra.net/vbb/showthread.php?t=57473&highlight=fuel+pump+change personally I'd rather just pull the fuse out...

There is one in the rear left corner as you look in to the boot, might be under the polystyrene Link to comment Share on other sites More sharing options...
Jake Posted February 19, 2006 Share Posted February 19, 2006 When I did mine I didn't disconnect the banjo bolt from the fuel tank - big mistake! Once I undid the first pipe into the fuel filter petrol started pouring out. 'No problem' I thought 'it'll stop in a minute'. Wrong! Due to the syphon effect the petrol just keeps coming out. It'll empty the tank if you let it! Link to comment Share on other sites More sharing options...
veilsideTT Posted February 19, 2006 Share Posted February 19, 2006 Ha ha, i did this too! went for a cuppa and when i got back i had about 5lts of fuel in the drainer!

JohnA Posted February 19, 2006 Share Posted February 19, 2006 surely it would be easier to take the fuel injection fuses out ... The pipes would still be pressurised though;) Link to comment Share on other sites More sharing options...
letmeshowyou Posted February 19, 2006 Share Posted February 19, 2006 as they would be if you just undid the electrical connector the trick is to start the engine afterwards Link to comment Share on other sites More sharing options...

It'll empty the tank if you let it! I did and thought exactly the same as you Jake, with petrol pouring out I decided to just get it done as quick as possible which was ok in till the petrol started to melt my tarmac driveway, not a problem I thought I will just hose it away, I now have a hole in my drive oops:banghead: Link to comment Share on other sites More sharing options...
Angarak Posted February 27, 2006 Share Posted February 27, 2006 How long have you had the car? If you are not sure whether it has been changed, it might be worth doing I've only had it 4 months now, its 10yrs old (1 prev owner in Japan) and has approx 23k miles on the clock. Think I'll look into the cost of one. Link to comment Share on other sites More sharing options...

Ian C Posted February 28, 2006 Share Posted February 28, 2006 Once every 3 years I think. They are under £30 and easy enough to change if you can get under the car. -Ian Link to comment Share on other sites More sharing options...
Chris Wilson Posted February 28, 2006 Share Posted February 28, 2006 I'd change mine every 30,000 or 2 years, whichever came soonest, the filter is SMALL for a 3 litre turbo engine at over 1 bar (equivalent too a six litre), so any muck in the tank that passes the pick up sock can soon choke the fuel filter, and they also act as a bit of a water trap. Better safe than sorry with something that could cause the engine to run lean. Link to comment Share on other sites More sharing options...
Guest AMW Posted July 23, 2010 Share Posted July 23, 2010 I have finally got around to changing my fuel filter after 14 years I figured it was probably overdue. If you don't want to be swimming in petrol, look under the rear passenger side of the car, directly above the drive shaft you will see where the metal fuel line joins a rubber fuel hose. Pinch this hose with a hose clamp pliers (or self locking pliers) to stop the flow, careful not to damage the hose. Now when you undo the fuel filter you will only get half a cup full of petrol leaking out even with the system pressurised. The banjo end of the filter needs a 17mm spanner and is easy enough, the other end has a flared end connector which is 14mm BUT if you use an open ended spanner you will probably round it off, buy a 14mm brake pipe (flared end) spanner. They are like a hex ring spanner but have a slot so it can go through the pipe, it is well worth the £2. Link to comment Share on other sites More sharing options...
