Busa fuel pipe
Am i right that my busa will only need a feed pipe from the in-tank fuel pump and won't need a return. If so how does it regulate fuel
pressure?

not all of the bikes had it -according to haynes they put the fuel pump and regulator in the tank in 2001 - so if your engines beefore that it may
have a return - just look for a return pipe to it

Cool thanks. Mine is later than 2001 so just one pipe then.

Just a word of caution but its your call,
If you run the busa pump in the tank you will have a high pressure fuel line from back to front, not something personally I would want it will also be
prone to Air locks until its properly bleed which could be a while, I have heard of people getting airlocks in the system done this way. Remeber its
just a short little run on the bike ?

I have been running a Suzuki fuel pump in my car for 2 years now. Never had any problems, the pressure is constant and the fuel line run is simple as
there is no return back to the tank. i am amazed at how complicated some people have made their supply of fuel to the engine. Keep it simple and use
the pump that Suzuki designed for it and i can say you will be pleased with the result. Even if you have a pre 2001 engine, you can still run the
later type pump. you just have to remove the old pump from the rail and have only one supply to the rail.
See my Photo archive for the pre and post modification.

If it can't be fixed with a hammer then its probably an electrical problem.

You have full pressure in the fuel line in a normal system also

Full potential pressure of the lift pump yes, 3 psi in my case, that's a lot less than the 50 or so a hp pump delivers, its personal choice but
having had a fuel line rupture in the past I prefer not to have 50psi + behind it, not that a low pressure leak is advisable either.
