Seems I have the common problem with bug wrx's rubber fuel pipes leaking under the inlet manifold. Does anyone know what diameter fuel pipe I'll need to replace this?...........can't wait to pull the inlet manifold of for the second time this year

 

SAE J30 R6. 5/16" is the rubber fuelpipe on my Blob, so that one.
Trev

 

Excellent thanks for that Trev, bit of a result as i have a length of that sitting in my tool cabinet it turns out
