I've used 8mm Micro bore for my fuel lines joined to components using gates 3225 hose which has a working pressure up to 1MPA.
I decided to re route a part of the line and went and brought some more hose but it's Codan hose with the following written on it "Fuel hose BSAU 108/2-L4/C4R & SAE J30 WP 12 bar" can anyone tell me that this is 100% suitable for fuel injection application?

if it says fuel hose and 12 bar that is suficent for injection

From memory 1MPa is 10 Bar so 12 bar hose should be fine. Not many injection systems run over 10 bar - The Pacet pump I bought for mine is 7.5 bar max

1 bar is just under 15psi so you're looking at about 174psi so should cope with anything your pump can deliver.

Thanks chaps most appreciated
