Install/removal is easy but get a Walbro...

Unless you don't have the cash... Please don't give such empty advice.

Since chances are he has an NA, adding a pump with higher flow that would over-run the stock FPR would cause the car to run rich at idle and low loads, compounding an already problematic carbonizing problem. To get a walboro on an N/A, you need the TII resistor pack or an aftermarket FPR.

Easy. Remove the cover in the hatch area, disconnect the wiring harness, remove the 12 or so bitch *** rusted screws (you will strip and break some... use the craftsman stripped screw remover, plenty of penetrant, and maybe slot a few of the really hard ones for use with a flathead). Swap the entire assembly, and reinstall.

If you only have the S4 pump, you will need to unscrew a couple screws and pull off the old pump and disconnect the wiring... but it's easy to see with the stuff out.

The only hard part is the screws on the top of the pump cover.
