1976 Bosch/Lucas Fuel Pump
The inlet of the pump is the larger fitting at the top of the picture, and the outlet is the smaller fitting sticking out the side of the pump at the bottom in this picture. This is actually the check valve screwed into the side of the pump. Here's a pic of the check valve itself:
The replaceable check valve on the XJ6 is a notorious source of trouble, causing difficult starting due to pressure bleed-off in the fuel rail. It's not known if this check valve is the same item or shares the same reliability problems. If the check valve causes trouble, you can either replace the check valve itself (as Sowell did), install an additional check valve in the line after the pump, or replace the entire pump with the later Bosch/Lucas pump which doesn't seem to have check valve problems.
Here's what the pump looks like in place:
Get a load of that outlet piping! That fuel is probably dazed and confused after all that loop-de-doo stuff!
Here's a pic of the same area with the pump removed:
Just for grins, Sowell threw in a pic of the pickup pipe and filter from the surge tank.
Note that this is clearly the later retrofitted intake screen as evidenced by its large diameter. The original intake screen is much smaller, barely larger in diameter than the pipe itself. This retrofit with the larger screen is highly recommended.
