High pressure fuel hose on sending unit
Is there a replacement part number for the short section of high pressure hose that has threaded connections on either end that is connected to the hard line from the sending unit? I bought a car that was sitting in a field for 25 years and have recently been going through the fuel system. All of those rubber short lines connected to the sending unit have seen better days.
Thanks,
Steve

Re: High pressure fuel hose on sending unit
I bought a new sending unit. The hard lines run along the top of the tank and then turn down on the drivers side of the tank. There are 4 hoses (jump over lines) that connect each line. One is the fuel return, one is the vapor line, one is the over pressure line, and the last is the high pressure line. All except the high pressure line are connected with hose clamps. The high pressure line is a 16mm IFF fitting. At least on the sending unit side it is. The other end has a rubber hose with the correct fitting but it is permanently attached to the hard line that goes into the fuel filter. I just ended up buying a 12" long AN braided hose and the correct fittings and cutting/flaring the hard line that goes into the fuel filter.

They also make it in a steel version for a few bucks cheaper. For the small price difference I'd get the 304SS version.
