unplug the 3 wire electrical connector thats on the drivers side coming out from above the gas tank. Start by either emptying the gas tank (removing the schrader valve & attaching a long hose stuck into a gas can would work good for this purpose, use the electrical connector behind the alternator to keep the pump running) or support the buick gas tank with a hydraulic jack (but you won’t be able to pull it out from under the car unless you put the car on jack stands or a ramp if you have the tank on a jack).Ģ. The 3 metal lines that connect to the gas tank will drop down enough for you to do this, without unconnecting them from the car, since there’s rubber connecting sections on them that give you the clearance you need. You can drop the gas tank without the car being in the air, there’s enough room for it to drop down & be able to pull it out from under the car (assuming there’s not much gas in the tank). Racetronix also recommends using their hotwire kit for proper support of the new pump, but pretty much any buick fuel pump hotwire kit will do. This is also big enough to grow into, if your G body isn’t quite at that level, yet.

It’s a big enough fuel pump to support mid 10 second cars if you have the proper other goodies, according to Racetronix. Short of going the double pumper route, this is probably the best choice you can make for your Buick Turbo Regal! (assuming of course, that you’re NOT running E85, which then, you should opt for the 416LPH pump). When your fuel pump finally goes out, or you decide its time to do an upgrade on your Buick Grand National or Regal T-type, the stainless steel fuel sender / 340LPH fuel pump combo made by Racetronix is a great choice!Įasy to install, bigger & reliable pump, upgraded wiring & the tubes have smoother radius bends for maximum flow & performance, amongst other good upgraded things that were incorporated into this model!
