A higher flow pump wouldn't be a bad idea if you have some plans for serious mods in the future if you haven't done some already. Otherwise, a stock pump is adequate.

Unless you have the need for more fuel, like major mods you do not need to spend 200+ on a better fuel pump.

The actual swap isnt all that hard actually. Basically you get the rear end up in the air, supported by the frame rails in front of the LCAs so the rear can hang down. Drop the muffler to the ground (if you have aftermarket and you can easily pull it out completely do so). Then you pull off the heat shields, unstrap the tank and pull it down. You will also need to take out the plastic surround at the filler cap, and possibly use a long screwdrive to bend the tube enough to let the tank rotate out.

Whatever you do, dont be lazy and just cut the floor in the hatch like some people do, cause that is down right ghetto

Remember too that the Walbro 255 is a high pressure pump. If you have TBI, you will not need 65 PSI of fuel pressure. You'll be better served with the proper fuel pump.

I also found that it is advantageous to remove the panhard bar. I also disconnected my brake line and dropped the axle by removing it from the shocks. After that, removal of the fuel tank was not bad, though you will have to wiggle the fuel neck out of the chassis and that takes some weird turning of the tank. That's why it's important to get the car as far up in the air as possible, and why it helps to get the axle out of the way.

Re: Im making the dive

run the walbro, whether it's TBI or TPI it won't matter since there's a pressure regulator on the throttle body/fuel rail on the TPI. I even run the walbro on carb'd cars at 7psi with a return style regulator, it won't be a problem and will flow more than enough for whatever you're doing.
