1975 240D Relocate Fuel Filter

Hi,

I need to know the size of a fuel hose.

It's the clear fuel hose that returns fuel from the injector pump to the top of the fuel filter. The barb connection on top of the fuel filter and the banjo/barb fitting on the back side of the I.P.looks to be slightly smaller the the other banjo/barb fittings on the fuel filter. I have 5/16 hose on all my other banjo fittings and would think it would be the same size, but it looks smaller.

I'm trying to install the Electric Fuel Boost Heater Kit. I need to relocate my main fuel filter just a few inches to get all my clearances. My only limitation is this hose. I don't want to cut if off until I know if my 5/16 hose will fit.
