Chevy blazer 2001 2door 4.3 liter replced fuel pump dont know how to reinstall plastic fuel line clamps at pump

The fuel pressure and return lines are two different size. They can only go on one way. The evap emissions line has a connector without a white or clear looking plastic piece in the quick connect.

I’m happy to assist further over the phone at https://www.6ya.com/expert/jeremy_d728a59f986299fa

I had a 1997 s10 4*4 with the 2.8 v6.
mine do that I had to pull the gas tank replace fuel filter plus had to take undo the line from the intake and blow air thru it. Make sure all u're filter are replaced and y u have the tank down replace the fuel pump. I hope this helps u

yes you have to drop the tank as the pump is in the tank.WARNING you may end up putting lines and a sender in aswell if they are rusty.

In the glove box behind a plastic panel. There are 3 relays in there. The fuel pump is the one closest to the drivers side.

IS THE CONNECTER @ TOP OF INTAKE WHERE FUEL LINES GO IN FULLY SEATED SOUNDS LIKE INJECTORS ARE NOT GETTING SIGNAL TO FIRE

You may have vapour lock in your heater lines. Start engine, put heat lever on high, disconnect one of the lines on your heater core, the one on the flow out side, & see if you have any air coming out. Once antifreese comes out stick line back on & retighten clamp. Make sure your cooling system is topped off. Also your water pump may not be functionihg to it's maximum. Take rad cap off cold & view flow rate. If inadequate you may have to replace the water pump. Good luck!

hmmm. if your sure that it is getting fuel than the starter itslef might be going out...

it is definitely the FUEL PUMP or FILTER then ;-) - or a blockage in the line.
I have heard it said that when the Chevy fuel pump goes, it self destructs and may leave (clogging) pieces in the tank (ugh)
Pump is IN the tank, so be extremely careful if you try to fix yourself. Fuel filter us UNDER the tank and cost $11.99 at Walmart.
My pump makes noise when I turn on the Key (but not starting) and so I thought it was OK too... but a Pressure check at PepBoys showed it LOW. $351.00 to drain, clean and replace pump. (another ugh) so I toodled over to Wal Mart, bought a Fuel ffilter for $11.99 and swapped ourt (pay attention to the ARROW it must point towards the FRONT of the car ;-)

Mine was full of coffee-like tar sticky stuff, so a quick change, new clamps (Use SSteel as these will not rust) and Bang, I was OK again.

CLAMP the fuel line coming in from the tank with 2 pieces of wood and a VVise-Grip pliers or C_Clamp. Don't want a face full of gas. Do the same on the ENGINE side of the filter.
Looen the 2 hoseclamps or twist them to break of rusted, and spen some time prying off the old hoses. Put a box full of crumpled newspaper or shredded stuff *sawdust works too) under the filter (on the ground) to catch the fuel or goo that will run out of there when the hoses pop off.

I took off the clamp on the Engine side, and let the fuel from the engine run out into a jar and it was uckky goopy brown too, but the last was clear so I let it drip out. After I wiggled the hoses and pried the old one off, I loosened the 3/8 nut and bracket and slid the OLD one out, and put the NEW one in. Then I put dishsoap on the nipple of the NEW filter and inside the old hose and pushed it on, then put on the hoseclamp and screwed it down tight. I then reattached the front hose the same way, put on the clamp, and now I had a new filter on the car. I still suspected I'd have to swap pumps.. but it was a $12.00 chance I'd definitely recommend to anyone ;-)

Make sure clamps are on RIGHT and hand TIGHT, hose on all the way and both clamps 1/4 inch from filter body, then take off the tank side Vise-Grip or C_Clamp and look for leaks. OK?

Then take off the ENGINE side clamp and look for leaks. OK?

Now go turn on the key so you hear the pump, let it stop making noise, and turn key OFF. Do this 20x to get fuel into the engine again. Then PUMP the GAS pedal 3x, hold to floor and start the car. As soon as it goes, slowly pump the GAS pedal and keep it running, but not RACING the motor!, and get it to idle again by itself (all air out of the fuel line)

Now go back and look for leaks. If there are any, STOP the motor and tighten clamp(s) just a bit. You dont want the clamp to CUT or CRUSH the hoses, just hold them tight.

Well Done!!

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
