Turbo fuel pipe ??

[Mike750]

Hi there I'm in the middle of building my gsxr 750 turbo and was wondering what fuel pipe to use now that I'll be using a fuel pump? But the t pieces on the carbs are only plastic so wasn't sure about the pressure, and if I wouldn't crush the t pieces. Thanks for any help

Ordinary normal fuel pipe is fine and the tee pieces will survive considerably more pressure than you will be throwing at them! You don't appear worried about the plastic floats being crushed so why the tee's in particular?

In answer to the question, the plastic t pieces are fine

Why are the floats of any relevance whatsoever I have no idea? Different material, not under any pressure from the fuel pump at all, the pressure they are under is from boost/air pressure and is less than the fuel pressure in the pipes, and they are sealed and have pressure on the inside acting against the outside pressure. 

I dont understand the need to mention them and wouldnt worry

The pressure is on the inside, you’d need a vacuum to crush them from the inside.....or pressure on the outside.....

.....the plastic is up to the job

The point is there are far more fragile things than the tee's ie. the floats or the carb tops! And contrary to your statement 'floats have pressure inside' - they do not - just atmospheric from when they were moulded and so they have to cope with external atmospheric air pressure plus boost pressure.

They do have pressure inside!!

What happens if you try and squeeze a bottle with the lid on underwater? The trapped air acts to resist the crushing, same in a float. Yes it will compress but it will take more pressure than if they were oper to atmosphere, just like the outside of a fuel pipe. And a good condition carb top isnt weak and also subject to less pressure than the fuel t's.

But go ahead keep adding more poor answers to questions that werent asked

Thanks for the help I just wasn't sure it's my first turbo project and was just starting on the fuel side of this, turbo and manifold done and plenum And pipes, fuel and wiring next , thanks
