I need a diagram of fuel system for an 88 tropper2.i am looking to find out where fuel lines run after it passes fuel filter and is about to enter fuel injection rod

You can't by pass a fuel filter,you need that

You should have seen & checked the condition
of the "o"ring on the fuel line tubing

save yourself some time and look under the truck and trace the fuel lines from the fuel pump. The line with the gas filter in it will be the pressure line and the other will be the return line. Not sure if that helps but it is better than wasting your time looking for a diagram for two fuel lines.

no carb on that car look for a 1 1'/2 '' can with a vacuum line sounds like the fuel pressure regulator failed

The other steel lines beside the filtered line are also fuel system related. One is a fuel return line the other is the EVAP line or vent line from charcoal canister (as most call it) to fuel tank. They can be replaced with new lines available at local parts stores.

in carborator where fuel line enters carb remove 5/8 in line then remove 15/16 nut where 5/8 line went in fuel filter is behind 15/16.nut replace seal (plastic) replace fuel filter GOOD LUCK B. HARRIS A.S.E. CIRTIFIED 25YRS. EXP

Fuel Filter REMOVAL & INSTALLATION CAUTION
NEVER SMOKE WHEN WORKING AROUND OR NEAR GASOLINE! MAKE SURE THAT THERE IS NO ACTIVE IGNITION SOURCE NEAR YOUR WORK AREA! 1970-83 Carbureted Engines The fuel filter is located on the right inner fender in the engine compartment. It is a disposable cartridge type.

1. Using a pair of pliers, expand the hose clamp on one side of the filter, and slide the clamp further down the hose, past the point to which the filter pipe extends. Remove the other clamp in the same manner.
2. Grasp the hoses near the ends and twist them gently to pull them free from the filter pipes.
3. Pull the filter from the clip and discard.
4. Install the new filter into the clip. Push the hoses onto the filter pipes, and slide the clamps back into position. Start the engine and check for leaks. Fig. 1: Fuel filter - 1970-79

1984-86 Carbureted Engines The fuel filter is located on the inside of the frame above the left rear spring front shackle. Changing the filter is VERY awkward. Since it is in-line and below tank level, fuel will pour from the fuel lines when they are disconnected from the filter. The only way of preventing this, is to siphon all of the gasoline from the tank before replacing the filter. Another possible method is to clamp and plug the fuel line, but this is not recommended because of the danger of leaking fuel or damage which could occur to the fuel line when clamped. It would, therefore, be a good idea to run the tank almost dry before changing the filter. Once the tank is dry, disconnect the fuel lines at the filter, unbolt the old filter and install a new one. Reconnect the fuel lines, fill the tank, start the engine and check for leaks. Fig. 3: Fuel filter - 1984-86

Fuel Injected Engines WARNING
Never attempt to remove the fuel filter without first relieving the fuel system pressure!

1. Release the fuel pressure from the fuel line as follows:
   1. Remove the fuel pump fuse at the fuse box.
   2. Start the engine.
   3. After the engine stalls, crank the engine two or three times to make sure that the fuel pressure is released.
   4. Turn the ignition switch OFF and reinstall the fuel pump fuse.
2. Loosen the hose clamps at the fuel inlet and outlet lines then slide each line off the filter nipples.
3. Remove the fuel filter.
4. Replace the fuel filter. Always be sure to use new hose clamps. Fig. 7: Fuel filter - 1986-88 VG30i

It's located where the fuel line enters the carburetor. I'm not exactly sure what you're asking. But in any event. Remove the fuel line without twisting it. Remove the filter housing (it too unscrews) remove the spring that holds the filter in and remove the filter. The filter is installed with the opening facing out towards the fuel line so that fuel can enter the center, pass through the filter, and enter the carb.
Hope that helps.

you dont need diagram, start under the car at fuel tank and follow the fuel line in the direction of the engine you will find the filter it is a silver bottle, if the fuel line enters the car before the engine bay then the filter is in the engine bay find where the line re-enters the engine bay and follow it. ( rate me thanks )

fuel flow is from tank to seperator filter then to supply pump on block now under presure to the secondary filter on the engine in the valley from there to the injection pump fuel not injected leaves the injector pump through the check valve at the top front of the pump entering the return lines withe the lines from all the returns on the injectors back to the tank. Yes the primary filter is on the **** side and should not be opened while running or cranking. hope this helps. Jim

The Lines are simple if it's a 2.4 EFI the lines run on the driver side inner rail from the center top of fuel tank, and up the middle of the firewall to the injector rail or throttle body carburetor there is also one line that runs from the evap canister back to the tank and to the fuel system three lines total one is a return line the large line is the main fuel line and has the fuel filter mounted on it and is under the driver side door inside the frame rail.
