Seriously, I'm with TJ, Andy, and everyone else who mentioned Bosch pumps.

I've had first hand experience with a Walbro pump, and had nothing but trouble with it. I also know of a few other cases where trouble has arisen.

NEVER seen, or had any problems with Bosch pumps. Its worth paying the bit extra for.

A Walbro is a direct drop in, because its identical to the stock pump minus a Walbro symbol on the side.

A Bosch pump means you'll have to tweak the fuel pump assembly, but its hardly difficult!!

Just requires you to cut down the metal outlet tube, run a piece of hose from the sock to the pump inlet, and from the pump outlet to the outlet tube and secure the whole shebang with a hose clamp!
