Yamaha HPDI mystery filters


Going to do a thorough fuel service on my 250 HPDI soon, and replace the basket filters (AKA the mystery filters) on the x6 injectors and probably also the x4 on the high pressure fuel pump.

Whilst most engines will by now have been fitted with newer powerheads and HP pumps, (given they had a habit on exploding when they were first launched) this seems to be one of the few things you can do to prolong the engine, and seems to be a regular service routine in the USA but not in the UK. My engines done c500 hours and no idea if they have been replaced, but I doubt it. for about 15 versus about 5k for a new powered or c 1.5k for a new HP pump it seems a bit like no brainer.

I'm ordering the original 6mm x 14mm not the slightly shorter universal ones. I'm ordering in bulk qty from the USA, so if anyone wants any let me know. They are going to cost some where around 1.50 each dependant on the import tax/charges. I should have enough spare to sell 2/3 sets.

I wont have them for a couple of weeks. PM if interested or text me on 07824 868659.
