I am installing a Walbro 255lph fuel pump into my 95 GS. I was able disconnect the rubber feed line from the hard line connection just outside the fuel pump, but the collar on the rubber line does not spin due to corrosion. So when I unscrewed the fuel line the rubber line got all twisted up. I'd like to put a short piece of new line or something between the rubber line and the pump hard line so when I reinstall the rubber line, it won’t get all twisted. Does anyone know what size thread those feed lines coming out of the pump are?

Thanks
