I noticed that there is an inline fuel pump (I think) beside the fuel filter underneath the car. There is also a pump in the tank. Is this two pumps or is it something else ? Where should the fuel pump be in this model, 2.3 auto 1991

I'm not familiar with the details of the coupe (mine was a 2.3E saloon), but I think you'll find that the smaller item is the fuel pressure damper required by the Bosch CIS-E system.

Pulses in fuel pressure from the fuel pump are damped, to avoid affecting the plate position in the metering head.

It also maintains residual fuel pressure for easier hot starts.

Ian.

Often called the fuel pressure accumulator. Looks like this
