91 Chevy Blazer gas tank needs cleaning.

bad body ground at tank connection, also check gauge fuse

you try filter down underneath in frame rail ?

You should not need any additional parts unless something breaks. Might be a good idea to see about getting a seal for the fuel pump if you intend on putting the one you have in the new tank.

Sorry for the new, but no. Your going to have to drop the gas tank on a blazer to get to the top of it.

Thank you for using Fixya and be safe.

YOU NEED NEW SPARK PLUGS AND WIRES.CLEAN THE FUEL INJECTORS.BUY A BOTTLE OF INJECTOR CLEANER POUR IN FUEL TANK OF GAS ALSO.CHANGE FUEL FILTER THIS LITTLE TUNE UP SHOULD HELP.

the only thing i can help you with is the replacement. go to a big scrap yard, give them your measurements, and they will find a gas tank for you. my gas tank was about $100 and my friend put it in for free so i cant help you there.

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.

try buying some starter fuild. if that dont work try checking the gas filters. if thats not it your erg value may have a carbin build up. that will need to be clean out. but most of all make sure you have spark

fuel filter is tucked inside framerail,just under driver side door,this location is not good,in extremely cold or snowy conditions the filter itself is known to freeze.

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
