Bike will hardly run. 2005 TC88 EFi

[Tooty]

Just thought you might be interested in this one. Andy and Edge just fixed a bike that came into the shop on the back of a trailer. It would hardly run at all, wouldn't tick over, huge spit backs through the throttle body.
Scanalyser showed various faults including VSS sensor, Throttle position sensor and front injector shorted out.
The fault was none of these things.

Decided to check the integrity of the high pressure fuel hoses both in and out of the tank. Removed all the screws that hold the pump and the tea bag in, and noticed that the high pressure line was not connected at the union on the underside of the tank. Also, it wasn't the proper Harley part! It was a bit of fuel line that had been just pushed on. No hose clip was fitted, presumably due to restricted (impossible) access. Result was that the high pressure fuel was just being pissed back into the tank. All the injectors got was the gravity feed that was present in the tank. I'm surprised it bloody well ran at all.

WARNING. Apparantly the Harley hoses are prone to splitting and they are expensive to replace. Please don't be tempted to bodge it yourself! You are unlikely to achieve an effective seal in the high pressure system, which is why you have to use the proper hose.

This might be better posted in tech Tips.
It's a great tip for those EFI folks out there.
Someone else I know had intermittent cut-out problems for ages on a custom tanked Fatboy. Seems the tank wasn't made with the same degree of accuracy as the stock one, and there was a bad seal between the Pump module and the trapdoor that somebody had tried to seal with some kind of mastic. Of course, the mastic found its way into the tank, and was getting sucked into the filter, clogging the flow, and starving the motor.
