1 Fuel tank removal to get at Radiator cap. Sun Jan 04, 2015 7:56 pm

I had a coolant dump so now want to get at the rad cap.
Tank hoses are too short to allow me to just pull it back so will have to disconnect.
Clymer says i must depressurize fuel system (P229) so I look for pressure regulator vacuum hose (fig 2) but I'm looking at RHS and can't see it. Is this on RHS?
So consider option 2, which is to disconnect the fuel pump electrical connector fr the main wiring harness (fig 4)
but can't see it either !!!!!!!!.
Under the tank LHS is a pipe (just behind the tank sender connecton),which drops down about 150mm on to the top of the injector rail, Looks like B in Fig 126 on p 263 but he refers to this as the fuel FEED hose.
In front of the T S connector is another hose but in fig 125 he calls this the fuel return hose . I can't see where it goes to but it seems that it will be difficult to get off the tank without pulling the whole LHS fairing outer off).
Am i looking at removing only two hoses plus the TS unit connector.
What i can't understand is how there's not going to be a gush of fuel when i remove the fuel feed hose or will this be almost zero because the pump is de activated?.
All this to get at a radiator cap !!!!!!. I'm glad my ute isn't built like this.
Any knowledge, clever ideas, get well messages, or drinks welcome -probably best in that order.
All of this may not be necessary, apart fr the fact that I want to lengthen the hoses so i can get the tank back next time, because the rad cap may now not need checking.
After the coolant dump, I refilled the reservoir, rode it for 40kms and checked the level. Didn't suck coolant fr the reservoir to rad when the engine cooled. Inferred fr this that the dump was fr reservoir only and nothing fr the radiator.
Topped up reservoir to slightly overfill before going to Grafton. Engine seemed fine and not overheating. Now 450kms later the level of reservoir seems much the same.
So seems almost certain that rad is full ??
