We have been having an intermittent fuel problem for the last two months.
Before doing the Thames Tideway I had replaced the main fuel filter as well as the fuel pump filter, this was done at least 3 months ahead of schedule but we didn't want any problems on the tidal Thames.
As you know, we survived the trip but it didn't go without a hitch. We started out from Limehouse using between 1600-1800 rpm nothing unusual there but about 2 hrs into the journey Richard on NB Indigo Dream called for an increase in speed so we pushed the rpm up to 2000+ then our troubles started, after about 2 minutes we started to loose power, throttle was retarded and power was restored, again pushed our rpm to 2000+, again loss of power again the throttle was retarded and power was restored so the remainder of the trip was done at 1800 rpm. Investigation of all the fuel system, Wasp filter, Main fuel and pump filter revealed no problems. Stumped.
Two weeks ago, when we had our friends Brian and Rosie aboard we had a similar problem whilst winding below Lechlade, but this time the engine almost gave up and stalled, having knocked it out of gear and gently teasing the throttle I managed to keep her running but only just. Investigated the fuel system again, and nothing found. I was beginning to wonder whether I had a problem with the injectors.
Tuesday evening I was reading, well scanning the new Towpath Talk where I saw an advertisement for a company called MLS Ltd who were offering a product which could possibly solve my problem, I investigated their Website and found out that they were operating out of Oxford. A quick phone call and two days later Ben below came out to MR at Thrupp and carried out a fuel condition test, free of charge.
I was knocked sideways, above is a sample taken from the bottom of MR's tank and as you can see 25% of the sample is water containing rust and contamination.
So, yes I bought the above, an FP100 Purifiner at a cost of £208+ VAT.
"When the fuel enters the unit the baffles in the system immediately induce a swirling action, which causes water and solid contaminants to separate out of the fuel. The contaminants sink to the base of the unit where they are retained – the contaminants are simply drained and disposed of when the system is full. "
Now only time will tell, however, in the meantime MLS Ltd also have a portable fuel cleaning system which can be hired at £30 a day which I shall probably take advantage of.

Once the water was separated from the sample the diesel was tested, the sample contained 1.9% biodiesel and 2081ppm of contaminants.
