  View original topic: Q about adapting 5mm to 7mm fuel line
raynman1972 Mon Sep 22, 2008 3:17 pm

I have a 73 SB non-fuel injected and I am adding an electric rotary pump from CB. My problem is that the line coming out of the tank is 5mm and the pump has 7mm going in and out.

Any ideas on how to adapt from 5mm to 7mm and then back to 5mm without a whole lot of brass adapters and/or leaking?

there are fuel filters with different sizes on each side.

Agreed, I have a fuel filter before and after the pump pn my KG for thsi reason. There are brass adapters though you can get at the hardware store.

Don't forget to install fresh new German-type woven fuel hose all thru your entire circuit as additional safety precaution.
