I just bought my blazer and replaced the fuel tank. as soon as i finished I started the truck and a line sprayed gas every where just behind the drivers door by the fuel filter. can i replace some of the line or is it best to replace the whole line? what are the fuel line sizes on all the fuel lines in the S10 blazer?

I have 2000 Chevy blazer 4.3 l v6 vortex I had the same problem I would spray starter fluid into the air flirted canester Nd it would start as soon as I stopped spraying the fluid the engine would die first I checked to make sure my gas pump was working in the gas tank second I checked my fuses under the hood and last the fuel pressure so my gas pump was on in the tank fuses were also ok but I had no pressure on the gas line so that ment my gas pump was bad I replaced it after replacing it my blazer fires problems free now
Since the fuel pump is in the gas tank, your pump picked up debris, and dirt on the bottom of the tank and ran it into your fuel filter.
Replace fuel filter, and check fuel pump fuse.
Running your vehicle with less than a 1/4 tank of gas is hard on the pump, because the fuel pump uses gas to cool it.
Please let me know what you find.
It sounds like you may have a weak fuel pressure. Check the fuel pressure at the shredder valve, there should be 62-65PSI with the ignition on the on position and should drop about 5psi when the engine is running. If your fuel pressure is less then 62 PSI, the fuel injectors will not function. To test this is to spry Carb cleaner in through the top of the throttle body and if the engine starts, then you have a weak fuel pump.
Start with the simple and replace the fuel filter and check the ground wire to the fuel pump on the frame of the Blazer.
If you do have a bad fuel pump "sending Unit", your going to have to drop the gas tank to replace the unit. Good luck and keep me posted, be glad to know your Blazer is running 100% again soon.
The fuel filter may be to dirty to let the gas flow through and will need to be replaced, or most common when you run out of gas is the fuel pump will burn it self out. The fuel in the tank will keep the fuel pump cooled and will keep it from burning out, if you ran it out of gas. The pump may have burn out and will need to be replaced. Check the fuse first and hope the fuse blown due to the extra amp drown from the pump running without fuel. If the fuse is good, then check to see if you can hear the fuel pump start up when you turn the ignition key to the run position. Note the fuel pump will only energize the fuel line for 5 seconds, so you need to listen for the pump to turn on right away. The other thing too, is you can check the fuel pressure at the shredder valve, there should be 62 to 65 PSI when energizing the fuel line and will drop around 5 PSI when the engine is running. Make sure you do not try to start the engine by pouring gas down the throttle body, it been know for the gas to catch fire in the intake manifold and burn up the fuel injector system which is very costly. Start with the simple and check the fuses and fuel pump, then replace the fuel filter. At worst, your going to have to replace the fuel pump by dropping the gas tank and don't forget to replace the wire harness from the fuel pump to the frame. Good luck and hope this helps, keep me posted. Be glad to know you got your Blazer running again soon.
Well, obviously someone didn't tell you the truth because spraying into intake doesn't make the vehicle turn over any better. You have ignition or fuel delivery problem. Start by taking fuel line off at intake and crank engine a couple times catching any gas in a cup or something. If none, then trace fuel line back and under vehicle til you find filter. Should be under driverside midway back on inside of frame. Change this and try test again. If no gas, see if fuel pump is on motor(mechanical pump). Change this and test again. If not on motor then it's in gas tank(electric pump). Most cases the tank has to be lowered to take out pump, careful not to drop, dent or make sparks. Some came with access through the floor so check that first. Normally you can hear an electric pump come on when you turn the key. Good Luck
you may want to check fuel pressure possibly fuel pump try banging on the gas tank with a mallet while someone tries to start the car if it is a fuel pump you may be able to get it started but pump will still need to be replaced
I had this same problem with my 1997 Blazer, which required a fuel pump replacement as Nitrobike said. The sign to look for is when you get in the Blazer, turn your key forward to the accessory position, but not the start position. You should hear the fuel pump charging. It sounds like a hissing or whirring noise for about 2-3 seconds while it pumps fuel into the lines to prime the engine.
Fuel pump replacement isn't cheap, about $700-$1000.
