I thought they were "small" cars?  type 85 or 89?  They have external
pumps down in the crud by the rear wheel.

New pump.  Should be $180 or less.

the 4kq/coupe with the 2.1 and 2.2 use the smaller outlet, the 80Q/90
and 87.5 cgt with the 2.3 use the larger outlet.  I'm pretty sure of that...

I don't know, but both my cars are running new Bosch units at that 180
figure.

Count on replacing the small plastic lines in the area as well, though,
under $10 each at a friendly dealer.  Also the rubber shock mount stud
things that hold the fuel tray, they are usually kaput by now.
