Fuel Pump Controller/Flange

Post by David. »

Whilst searching for photos of fuel tank removal, came across something which I thought was interesting & may be to others.

On the Hexhead, the orientation of the fuel pump flanged, caused water to pool around the fuel pump controller. This resulted in corrosion & electrical problems.

Image

On the Camhead, the fuel pump flange has been rotated, in order that the fuel pump controller & electrical connections are upper most.
Yes, water does still collect in the flange but not where it can cause any problems.

Image

For some reason, the fuel pump controller has changed colour from silver to black.

I may have posted pics of this home modification before but can't remember where, but this is a picture of my own method of keeping water away from the Fuel Pump electrics. I used the same mod on my Hexhead and transfered it to my Twincam as shown. Very effective and zero cost.
When the fairing panel is replaced the outer edge of the blue plastic "shield" is pushed down about 45 degrees and acts like an awning.
David's pictures also show the improved wiring and plugs on the Twincam. I believe that the different coloured Pump Controller started with a change of supplier. When my Hexhead controller gave up (in the middle of the North Yorks Moors) the replacement fitted under warranty was the black version.

Daft as it sounds, I used a J cloth and a tiny cable tie. On the periphery of the flange are several raised parts that can take the tie which then holds the J cloth in place. One end of the cloth is bunched and pushed into the water collection area whilst the other is spread out under the tank cover. This doesn't prevent the water getting into this area but it does wick the water away and the airflow does the rest thus drying the flange area nicely. The problems seem to occur when water is left to rest on the flange.
May the road ever be your friend, from leaving home till journey's end.

Having washed my TC RT before removing the fairing panels, I did notice that water pools in the fuel pump flange in the green area as per this photo.

Found a suitable size plant pot saucer, cut slots in the rim for the wires/hoses and placed it over the whole fuel pump flange. Hopefully that'll keep the water out in the future.

I always carry a spare controller, seeing as they're relatively easy to swap, even at the roadside. I picked one up for around £40 on fleabay. The original one on my 1200ST was silver, it had never seen a trace of damp even though the bike was ridden in all weathers. The spare I have is black - I was led to believe that the black ones are upgraded, and less prone to failure - over on UKGSer, the vast majority of failures reported are the silver ones....in fact, I'm sure a call was put out for anyone who'd had a black one fail, with no takers. Some owners cobble together a bypass cable to use should theirs fail, but I can't see the point - it's as easy to fit a spare as it is the bypass.

I've got all the plastics off my '06 RT at the moment - the controller is bone dry, in fact it's dusty around it and I doubt it has ever seen damp!

I think I'll give mine a whip over with the vac while I've got the plastics off  ;)

New improved version manufactured, using a 6" saucer rather than a 5.5" - 6" one, should keep all the debris out too.

Somewhere, in the depths of the garage, I have one of these, picked up used for a fiver - it's the purpose-made cover from the K25 GS. I never bothered doing anything with it though as mine never seemed to get wet! I think this may have been meant to keep out debris more than water, although it does form a seal around its base which would stop water getting into the recess if it was coming down from the top of the tank area.
