Changing them, also change the fuel filter if you havent done it in a while, better gas mileage, id just go to your local auto parts dealer and tell them you want a new fuel line linkage from the tank to the front connection, if there is one. not really sure if it goes all the way to the fuel rail or not, but if it does then have fun, drop the tank, remove hose, replace hose, replace fuel filter, replace other cracked hose, making the replacement hose as short as possible, dont cut it though, just a waste cuz your going to have to replace the rest of it anyways

Important: There is no service interval for in-line fuel filter replacement. Only replace the in-line fuel filter if it is restricted.
Relieve the fuel system pressure. Refer to the
Raise the vehicle.
Remove the fuel feed quick-connect fitting (4) at the inlet of the in-line fuel filter (3).
Remove the threaded fitting at the outlet of the in-line fuel filter (3).
Drain any remaining fuel into an approved gasoline container.
Inspect the lines for cuts, swelling, cracks, and distortion.
Replace the lines as required.
Inspect the O-ring on fuel filter outlet pipe for cracks or damage.
Replace the O-ring as required.
Inspect the fuel vent pipe (2).
Inspect the fuel return pipe quick connect fitting (1).
Located in the Carb.where the main fuel line goes into.Please use 2 wrenchs to remove the line and the filter housing otherwise you may bend and damage the fuel line. When putting in the new filter remove the rubber and spring that goes into the new filter....Tjis is not a necessary item and it will resiult in a better fuel flow.
Ihave not had any luck removing rusted filters without bending the line. Your best bet would be to cut the line a couple of inches back from the filter and re-install the new filter using rubber fuel line and hose clamps to splice it back together. BE SURE THE RUBBER LINE IS FOR FUEL LINE!
fuel lines inside the intake plhenum may be cracked and leaking inside the plhenum. same thing happened to my 1992.sonoma. they are made of a plastic material and tend to crack right in the bend of these lines.
If you can locate where the fuel line goes into the Carb. Remove the fuel line then the larger nut behind that.The fuel filter is inside the larger nut.It is hard to try and get the fuel line off without both moving or twisting the fuel line,and most times there is not enough room to bend it out of the way to get the fuel filter out.If all else fails you can cut the metal line just leave a few inches back from the nut then when reinstalling you can patch it back with a rubber fuel line and clamps.You may also look into installing a inline fuel filter in better location.Well hope this helped.
sounds as if its either a vacuum leak such as dry-rotted or cracked even the line itself has come undone causing a manifold leak which will cause this as well as it may be the fuel filter or insufficient fuel pressure a wire that is arching ...open the hood and look for the obvious first such as a wire rubbing metal or on the engine a bad plug wire can be tested by bending them for cracks as well as the same way for vacuum lines you can also use a spray bottle of water to find a wire that is arching or you can use brake cleaner to spray around the manifold and vacuum lines for when it either dies out or accelerates and you should find it this way if that is the cause however it may be the fuel filter is struggling to push gas up to the fuel bar check these areas 1st
it sounds like a few possibilities ..a clogged fuel filter a bad or broken even missing vacuum line cracked causing this a faulty idle sensor when was your last tine up / ...also fuel injection rail is getting clogged faulty plug wires maby bad plugs byt most likely one of the above fitst few to look at first try bending the vacuum lines for brittle dry rotted or even missing in position try looking for the obvious even a clogged air filter will cause this
check the transmission fluids as well as all other fluid levels as long as you are there as well as it may be a fuel filter or fuel pump pressure issue but start with those areas 1st and be sure to check all vacuum lines for cracks as well as the bending plug wires to ensure no cracks are present
Did you replace the fuel filter? If you did and did not pre-fill it with fluid, it won't work, Try cracking lines to each diesel injector while turning it over (open the lines slightly to let air bleed out) Hopefully that'll get you somewhere.
Some of these cars have a platic/nylon fuel line. I would check the fuel line for wear or cracks. They do make a repair kit but it takes a couple of hours. Those particular filters do not have a rubber gasket. The crack in line is usually at the 90 degree bend where the fuel line goes into the filter. It is a common problem on these cars.
