BSP-to-AN6 -adapter (which has a concave bottom) and a steel adapter to make convex from concave.
Not sure if this works, but this is going to be my spare fuel line adapter if that 5/16″ pipe fitting doesnt for some reason work with the stock hardline.
I went to see Beldin and his zoo (six dogs, two lizards and two children) and asked him about the hardline diameter. I used sherlockholmesian deduction that stock hardline diameter might be around 8mm on every japanese car just because every japanese car can be upgraded with a Walbro 255LPH pump that has a 5/16″ outlet. What a coincidence.
Below: two photos of Honda CRX hardline – 8mm as I suspected. My cellphone had so little charge that I couldnt use flash and Beldin left his phone inside.
