Peter. One of the things a fuel filter cannot prevent is the formation of olifins on the injector pintle and nozzle due to rapid drop in pressure as the fuel exits the injector nozzle. This can also cause problems on the back of inlet valves (eg. Some BMW, NISSAN and TOYOTA TERCEL etc.) BMW actually came out with a crushed walnut shell abrasive blaster that you used on the inlet valves with the inlet manifold off. The term they used was "cauliflowering" A soft, porous deposit that actually absorbed fuel on cold starts and led to hesitation on cold and warm-up driving. Olifins were/are a major problem on heavily cracked fuels - typical in Australia and Mexico in the 1990s but I'm not sure of Europe and England. I could go into why olifins form after a heavy cracking process but I'll leave it there. The best intank additive I ever came across was ALFLOC L610 but read the instructions carefully -VBG. Other alternative treatments were pressurised cans on the fuel rails etc. etc. Cheers Peter Wright
