See also the post about gasoline, octane, and ethanol. One ownership challenge about classic cars is that they don’t tend to be driven that much, especially during the winter in colder climates. Gasoline, especially when mixed with ethanol, was a shelf life that is typically a month or two. So......

Solex backgrounder
See also Solex rebuilding and tuning. Jaguar incorporated twin Solex carburetors for the Mark I and Mark II models with the 2.4 engine between 1956 and 1967, but deployed twin SUs for all the other XK engine models. Thus, the Solex is something of an orphan child among Jaguar World......
Fuel system boot connections
Installation of the petrol tank allows us to complete the fuel system connections in the boot. The fuel level sending unit is connected by three wires: a black ground that fastens to one of the unit bolts; an orange wire attaches to the “W” terminal for the fuel warning light;......
Carburetors and air intake
The twin Solex carburetors mount on top of the intake manifold, and there are a number of fuel, choke, and accelerator connections....
Manual choke control and switch
The 2.4 liter model, unlike the 3.4 and 3.8, has a manual choke (Jaguar refers to this as “mixture control”) operated by a lever housed in the left facia board. In addition to activating the choke mechanism in the twin carburetors, the lever triggers a switch that turns on a......
Fuel filter re-do
After cleaning and replacement fiber washers, hardware, and a yellow filter, the fuel filter assembly looks like new. Here’s the before and after comparison. The replacement filter is the long type with a spring on the bottom to hold its position. Since the filtering area more than doubles, this should......
Petrol tank and fuel level sender
See also Smiths small gauges and petrol tank removal posts. In anticipation of the tank installation, the petrol filler cavity on the left rear of the body was painted with POR 15 and fitted with a new grommet. The POR 15 coating should withstand gasoline drips better than the exterior......
Accelerator
Jaguar must have had a minor fixation on accelerator controls since they designed twelve different setups for the 2.4 Mk2 alone (some of the proliferation was necessitated, of course, by right-hand drive models). All control systems work in a similar way with various shafts, linkages, and control bars. The pedal......
Solex carburetor rebuild
See also background information about Solex. The 2.4 engine has twin Solex B32 PBI5 carburetors (the 3.4 and 3.8 engines have different S.U. twins) that need to be rebuilt. Each carburetor has over 80 parts, some very small, so it’s important to keep track of how the unit is put......
Fuel hard line (rear)
A snake-like hard fuel line runs from the left side fuel pump in the boot to a connection on the right side of the chassis main beam. A) Fuel pump connection in the boot B) Down from boot, line is clipped to rear body C) Runs along body, then up......
