ID of Fuel hose V5/6 STi
 

Anyone know the correct ID of the hose lines from the front bulkhead to the filter and then beyond to the fuel rails?

Thanks in advance :thumb:

BTTT

8mm :-)

Been told 6mm as well.

I saw that on anothe thread but my fuel filter/fuel rail lines are standard and are 8mm. Maybe worth checking for sure.

It's the inside diameter (ID(bore)) I am after to prevent confusion.

I'll call tomorrow.

I chcked mine today and it's deffo 8mm ID that's from the fuel pump to the feul filter and from the filter to the fuel rail. Same size on both my inlet manifolds, 1 being a 98 uk turbo and 1 being a 2004 uk sti. So might be worth getting a tape measure out :)

Is that by pulling the pipe off mate as the end where it go's onto the hard pipe can swell from being pushed over the hard line making it seem larger?

No I actually have some left over pipe from when I replaced all my lines, and I also measured the steel hard lines that the rubber hoses push onto. I'm confused now lol.
