The 998 arrived last week, and I’m not taxing it until July, so it’s been in my new Asgard shed. But I had to investigate the stink of petrol, lifted the tank to find a) the drain hoses weren’t connected and b) the leak was from the fuel sender. I know that the nut can crack and wondered whether there was a better replacement. (Ducati only supply the entire unit at c. £140) Also, when ‘investigating’, I found that the sender wiring insulation was cracked, exposing the copper cores! Presumably I can disconnect the pins from the plug and slip over some shrink wrap?
Alloy nuts are available, I bought a couple for my 916 and Monster though this was some years ago however a quick search finds; https://www.ebay.co.uk/itm/283683012126 https://www.amazon.co.uk/Ducati-Fuel-Level-Sensor-Nut/dp/B09MJ4LSWD https://www.corsasbk.com/product/al...748-851-888-916-996-998-ms-ss/?v=796834e7a283 As for the connectors, yes you can remove them or fit new but seeing how little is left probably a heat shrink repair is best.
Thanks. No. 3 is out of stock, annoyingly, as the other two are from the US and will take more time. I’ll await the decision of the ‘warranty’ company to see if they’ll cough up.
As the dealer will cover the cost, and as I have to pull the pump, I may as well replace the sender unit completely, to deal with the poor wiring. I’ll probably upgrade the nut, and the QR connectors too. More £ on its way out!
Actually, thinking about it, it may not need the pump out? as the one in the Monster which IIRC is the same part screws into the tank and there is no removable plate (you have to go through the filler opening for filter changes) but there is a connector from it inside the tank to the pump. Either way, if it were mine and I didn't know how 'fresh' the filter was, I'd be removing it all.
Started the fuel pump refresh today by pulling the pump unit. I am right, no? The pump O-ring goes IN the recess, not at the top under the flange?
…and the plastic QR fittings are b.. tight. Any clues how to extract them to replace with metal ones?
Given the state of the O-ring and the poor condition of the wiring, I’m less impressed with the previous owner/servicer
Any hints on how to unscrew the female QR plastic fittings? Mine only have two flats, and the top is too large to get a socket over…
They usually snap off when you try to remove them. The left over thread can be quite easily removed when heated up to the point when the plastic goes soft.
