Does any one have any ideas on where to look for replacements or any tricks to getting them clean?


Thanks

 

There are two: one on the sump tank outlet (the sock filter) and one after the pump, the large grey canister. Which one are you having the bother with?
Essentially, the first thing you must do is to clean out the entire fuel system, main tank, sump tank, and feed and return lines (these can be blown through with compressed air). Once the loose rubbish is out of the system you should be OK.
The sock filter can block, even when looking quite clean, as I have an idea the nylon mesh currently being used expands and clogs on contact with fuel. Depending upon funds, after cleaning the system, aftermarket racing filters flow much better than the grey canister does, and have cleanable metal elements.

In principle, yes. For a pre pump filter (to replace the sock filter butting it in the main tank to sump tank hose) 100 micron would be best. Post pump 55 micron or 40 would be best. The models shown do not have hose clamp tails, but I am sure they can be supplied/found. 12mm for the main tank, 8mm for the post pump.
I actually run a Sytec post pump filter with a re-useable stainless filter element, after endless trouble with the Bosch canisters. Quite honestly, whether a pre pump filter between main and sump tank outlet is really needed, as long as the pipe that feeds the pump is shortened a touch to be well clear of the bottom of the sump tank, I doubt.
