In addition to the parts from Racetronix, ideally you should convert to a return system with an aftermarket regulator mounted near the rails

Mallory
Aeromotive
Edelbrock
Magnafuel

If I had to buy a new one I would likely buy the SX Performance 15404

I know people who have done it with success but Racetronix says it will overpower your stock regulator. This could lead to premature pump failure and/or issues at idle.

I decided to go with a return system because it gives you the option to boost reference your fuel pressure

As stated before you'll need the GT280 bulkhead (and wiring) and a proplerly designed return system. The 3 parts linked above are offered by Racetronix in a single kit that's less expensive than buying everything individually. The pump isolator will need the bottom 1.5" cut off. You can retain the jet pump system by modifying the pump.

No different than the 255 that everybody modifies, INCLUDING Racetronix. Racetronix uses a threaded fitting, but the factory presses the fitting in, so why not do the same? Carefully cut the small brass barb out of the stock pump. DO NOT pry or pull on it. Drill a 11/64" hole in the top of the Walbro pump, opposite of the pump outlet, symmetrical to the pressure relief port - make sure no plastic drops into the pump. You only need to drill about 1/8" deep to breach the plastic. Press the brass barb into the hole - I used a 1/8" deep well socket. I have a few pics that I can post later.



Pump? Nobody said anything about including a pump. You can purchase the bulkhead, vapor connector, and hotwire harness as a single kit: http://www.racetronix.biz/customkiti...?kc=FPWK-017WX

Either did I, if you look at the kit you posted its for use with a 340 lph style pump, not the 267 which has a unique intake connector. That's why mentioned the cut/splice above.
