I'm currently replacing my rubber fuel
lines on my 31 year old Bukh
DV20. I don't have any information on hose size so I have been copying what I replace. In doing so I found some inconsistencys, the previous owner may have replaced a hose or two I don't know.
This is what I have
A 1/4 inch hose from my secondary filter back to a 1/4 fitting on the fuel tank
( my return line )
A 5/16 hose running from the other 1/4 inch fitting on the fuel tank
, to a 5/16 fitting on the primary filter, from there another 5/16 hose to my fuel lift pump
I am curious as to why a 5/16 fitting wasn't used on the fuel line at the fuel tank.
To mount the fuel line to the lift pump
the fitting appears to be 3/8 not 5/16, the hose was very difficult to remove.
The hose was either stretched or shrunk to fit
So my question is does anyone know the correct replacement fuel hose size for a Bukh
DV20? or is it set up correctly already?
