fuel line routing - pics needed

Svenn Ryen · #1 05-03-13, 11:55

Hi

The fuel lines on my C15A are cut off and replaced with rubber hoses. At the switch what i believe is metric copper tubing for connecting these hoses. My fuel filter was also by-passed

From what I make out tubing should have OD 5/16 and be of steel?

The picture in the manual does not show correct routing from what I make out, only the set up.

All info on fuel line routing from tanks to switch, switch to filter, filter to pump and pump to carb apriciated.

Pictures, sizes, hose lengths, thread/fitting sizes would be great.
thanks

Svenn

Cheers Phil

Thanks Phil.

These pics were great. What I need is som pics of the tubing from the fuel pump to the carb. Is this line fastened with clips somewhere?

Hi Svenn,

Not familiar with the C15A fuel lines as I am a Ford F15A person but first up never use copper tubing for fuel lines. Flexing will cause copper tubing to get brittle and fracture. The cabin flexes relative to the chassis on the rubber and spring cabin mounts so the fuel line on the chassis will flex between the chassis mounted fuel filter and the fuel valve attached to the cabin floorboard. Eventually it could fail if made of copper.

Assuming Fords and Chev CMP's have some things in common use 1/4" Bundy tubing same as used for hydraulic brake lines.
My Ford F15A fuel lines have double flares and SAE inverted flare fittings on the tank changeover valve. Again, same as used on brake lines. It appears the fitting on your changeover valve may be compression fittings using an "olive" to seal the tube as is often done with copper tubing. May work Ok with steel tubing also, but I prefer double flares.
If it is good enough to seal against hydraulic brake pressures it is good enough to seal against petrol leaks in the fuel lines.

Hope this little snippet is of some use.

Cheers,

Thanks. I will use steel tubing, but I believe it was OD 5/16 original on Chevys?? I also need some pictures of the line from filter to pump.
