New Fuel Line

New Fuel Line

So as I had noted in my last post, I felt that the main section of fuel line had to be replaced. I ordered a twenty-foot coil of 3/8″ copper-nickel fuel line and used my brake flare kit to set up a double-flare on each end. This line replaced what had previously been three sections of different types of tubing extending from the gas tank to the engine bay, each joined by rubber tubing and hose clamps.

The new line replaces all of that – the only line left in place was a nicely bent section extending from the driver’s side of the engine bay to the passenger side, where it connected to the fuel pump. From the fuel pump there is one more section of line extending to the fuel filter, which is then directly connected to the carburetor. I used an air compressor to blow out the lines I retained after they were drained of fuel.

Stumbling Along

Stumbling Along

Within a week or so after replacing the differential oil, Cornelius started to complain a little when going uphill. This was in the form of stumbling when the accelerator was applied.

Durex Fuel Filter Prior to Cleaning

Durex Fuel Filter Prior to Cleaning

My first steps were to check the fuel system and to clean the fuel filters in both the Durex Fuel Filter itself, and the fuel filter contained within the fuel pump. In the Durex unit, the fuel filter is composed of a brass porous element, which I cleaned by agitating it in Chemtool B-12 fuel system cleaner, then blowing through it with compressed air. The fuel pump filter was a brass screen, which was cleaned in a similar fashion.

The result of these efforts? Still stumbling.

L and R-Series Library

L and R-Series Library

For those of you that used to frequent the previous website – “Restoring Cornelia”, I have great news. I just completed transferring the L and R-Series documents from the site and have created a new “R-Series Library” page for you (contains as much L-Series information as R-Series, though).

In the new library you will find the MT-97 Parts Catalog, an Inter-Sub Manual from 1959, the CTS-11 Service Manual for L-Series Trucks with the CTS-12 R-Series supplements, a Carter YF Service Procedure for rebuilding the carburetor, the CT-62 L-Line Product Information No. 2 Sales Guide, and a Wiring Diagram for R-Series Trucks.

Love You Gearly

Love You Gearly

As with all old vehicles, you need to place some cardboard and/or absorbent pads beneath the vehicle if you want to reduce the number of oil stains on your garage/shop floor. I had been noticing that the pad beneath the differential seemed to be collecting a little more oil than I thought was desirable…

Also, since I hadn’t changed the gear oil yet in the differential, I felt I could take care of a few things at once.

The differential cover came off easily enough. The oil (as differential oil usually does) looked pretty sludgy. More importantly, I did not see any chunks of metal or shavings in the drained oil. Very happy about that!
