I have just replaced the fuel filter on my CVh Inj.
The filter is located near the metal oil pipes that goes to the offside kingpin and was in fact touching it. Luckily there has been insufficient vibration to cause rubbing and damage to the pipe. On fitting the replacement filter I have made sure it is nowhere near the pipe. On getting a new filter from a local motorfactor I also had to get olives to fit it. The input pipe is 8mm dia and has a compression joint. I cut the old filter to remove the nut and used a new olive for the new filter. Now refitted and ok. I have used the oiler system but not very regularly. I have recently cleaned up the hubs due to oily build up from excess oil from this system. My kingpins are sound and I have not seen a replacement in the service history from 2 previous owners. Mileage is 33,000. The kingpins feel good when tested and steering is A1.
I must have a lucky good set!
