How to change a fuel filter | Lister ST3 Fuel Filter

Over last weekend I thought Sirius had an exhaust leak until I realised that it was infact a fuel leak. The seal on the fuel filter had failed and hence it was dripping (well at one stage spraying) diesel onto the hot engine and then it was smoking.

I have ordered 3 new filters from Online Auto Spares who are a business selling engine parts via eBay, excellent service and Graham who has been emailing me is obviously very knowledgeable, thanks Graham!

Here is a photo of my Lister ST3 and the offending fuel filter:

The fuel filters are very easy to change:

1) Turn off your diesel supply
2) Undo the nut on the top of the fuel filter (make sure you put something underneath to catch any diesel inside the filter.)
3) Remove the filter (make sure you don't loose the spring inside!)
4) Give the filter bowl a good clean with some kitchen roll or rag
5) Refit the filter using the new rubber seals provided with your new filter
6) Don't over tighten the nut

Bleed the Engine (I.e. get rid of the air in the fuel line)

1) Open the small nut just above the fuel filter as shown in the view from above.
2) Turn over the engine until fuel starts to come out of the hole and then re-seal it
3) If you have further bleed points do the same again
4) Then turn over the engine until it starts, simples :)

I hope this helps someone!
