yes you have to drop the tank. you will also need a fuel line tool to unhook the fuel lines. before you drop the tank see if tou can reach and wiggle the electrical connection on the top of the tank. these pumps have a pigtail issue. please rate

The abs is a add on for the brakes that when the tires come into a skid or slid they wont lock up..Your brakes will still work great with the abs disabled but your brakes will lock up if you push on the brakes hard enough to stop.Mainly abs works in slippery conditions not letting the tires lock up and keep the car rolling instead of making it slide..But no effect of the brakes will happen..Just make sure your fluid is full and there are no leaks and if you want to get them check you can stop by your local Auto Zone and they will scan your car for free and tell you what sensor is bad..I hope this was helpful to you...Have a great night

Before spending several hundres on a fuel pump, I recommend doing a fuel pressure test. You can get a test gauge pretty cheap at a parts store. If the pump is junk, you raise the truck, lower the fuel tank, unplug the electronics from the pump at the top of the tank, then with a hammer and flat head scrwedrive, gently tap the lock ring in a counter clockwise direction until it pops off. Pull the pump assembly out and install the new one. Reverse directions to install.
