Pipe diameter - 8mm should suit either carbs or injection.....

...but pressure will be 1 or 2 psi for carbs or 45'ish psi with injection.

Really need to know which you've got

i= injection?

Agree that 8mm pipe will be fine for all instalations. Think that the pressure for carbs is a bit higher than 1 or 2 psi, my old 1600 Xflow used to run with a pump producing 4.25 psi. My present engine, (V6), injection pump runs 5 bar stalled, and thats a bit more than 70 psi, although the pressure regulator cuts that to around 3 bar, (42 psi). HTH Ray

Ive been told that 6mm ID will be o.k. for 200+ Bhp (injection @ about 3 bar)... In fact I bought some nylon hose from lolocost and the size is 6mm ID. I do hope they are right. I should sit down and calculate the flow rate I suppose......and check but that probably will make my brain hurt!

Anyone got a concern with 6mm ID?
