You have to do a flow test by seeing how many litres per hour the pump is pumping. Disconnect the fuel line into the rail, and then somehow apply 12v directly to the pump wires. I don't wanna tell you to get a 12v battery and use bare wires in your boot coz knowing my luck you'd blow yourself up and I'd get sued. So I'm not telling you to do that. But however you want to do it, you have to apply a direct 12v to the pump. It won't get an accurate reading from just cranking as after the initial prime the pumps speed slows to half as current is drawn to the starter so the pump doesn't get a full twelve volts.

You have to catch the fuel into a 2 litre milk container or something of that sort. Also I recommend the use of an approved fuel container but once again it's entirely up to you.

Posts your results here and I'll tell you what they mean. You basically have to work out how many litres per minute or litres per hour. So this means you have to time it. Two people are generally needed for this.

A fuel pressure test can really only be done with a fuel pressure guage. You won't need to test pressure while driving if the flow test comes up ok.

Really all you need to achieve both tests is a fuel pressure guage and a 2L milk bottle.

    • Absolute f*cking nightmare. I had to take breaks constantly, and I was always pissed off when I got home. The line split in Italy on day 2 (we drove from the Netherlands), lol. Driving any narrow European town was... well, sh*t.   Appreciate it man. Here, I'll just drop a favourite from the load I took on Saturday.   I'll update here when things happen with the car, the thing is, with stock power and almost everything chassis-wise taken care of, there really are no problems. 268,000kms now and counting.  
    • Ah! I actually managed to snag a lightly used set.... that aren't so suitable for me right now. They don't work on a GTT without some cutting or creative heat moulding. I thought about reselling them myself cause I didn't want to murder them, but it looks like I'm probably going to attempt to murder them/melt them because I may as well. @GTSBoy @PranK can somebody close this thread?
    • Hey mate,  I have a set, one is slightly damaged but wont be noticable once installed.  Shoot me a message if your still after them 
    • I couldn't wait But, the black constant tension hose clamps were too thick and there wasn't enough clearance at the T/B and I couldn't get it to seat properly, so I had use a silver one there I also added some 3" silicone over the alloy bit that goes through to hole on the radiator support as it looked like it was sitting on the edge of the hole in the radiator support, I never noticed a rattle or anything, but there was a witness mark It is basicly done, and I can live with the silver hose clamp at the T/B, I will get a black clamp for the head vent though where it is attached to the bulkhead fitting  It never stops...LOL, only issue now with the shock tower brace is it slightly touches the under bonnet liner now, if I leave it it will either wear some paint off the brace where it touches, or damage the liner, so I removed the liner to see what I have to work with, with the liner removed I have about 20mm of clearance, but sadly the middle part of the underside of the bonnet is only dusted with paint and looks crap, so I cannot have that, but.... as I have a roll of Carbuilders premium under bonnet insulation in the garage laying around that is only 5.5mm thick (we were going to use it on the boys Patrol, but he crashed the front of it a few months and it was written off, hence why he now drives my old Honda Accord Euro), I'll use the OEM liner as a template and get the Carbuilders stuff fitted up to cover that dusted paint up
