  1. Thanks for the replies. I've decided to bore the pieces out to 5mm for a bit of head room. Probably unnecessary but then converting a working bike to EFI is unnecessary too!
  2. Thanks that's helpful. Looks like I'm gonna have to make some changes. There's probably room for me to drill out the 4mm pieces to 6mm however on closer inspection, the pump outlet is M10 and with the AN6 adapter screwed in, there is only 5mm exposed for fuel to flow to I suppose its pointless going above that. Odd as I wouldn't have thought 5mm would support 155 lph either
  3. Hi colinworth, thanks for your reply. The rail is lifted directly from a 01 gsxr 1000, so the 4mm sections I was talking about are presumably ample for flowing enough fuel for ~160bhp. However as this rail is from a return less system, I was just worried the change of diameter would mean different sections experienced different pressures. I just don't want to get it together and realise it doesn't work The pump I'm using is a walbro gsl393 which does upto 155 lph. Do you think those 4mm sections are wide enough for that volume? If they're not does the pump just fry itself? Thanks again Dan
  4. Hi everyone, I'm new on here so please be gentle. I'm doing an efi conversion on a bandit 12, but my question is relevant to any EFI conversion. My question is does it matter if the diameter of my fuel hoses / fittings are different throughout the system. So my fuel pump supplies the fuel rail via AN6 hose, then the rail itself is 4mm ID, then it widens up again to AN6 to supply the pressure regulator. I'm thinking the change in hose diameter will make the pressure regulator see a lower pressure than the fuel rail does and so allow the fuel rail too much pressure? It would make more sense to me to run the regulator before the rail but I have read this is a bad idea. Any thoughts welcome Thanks for your time Dan
