How to replaceing fuel vapor hose 1986 spider

Fuel vaporizer????

Could be the main or fuel run relay located in the compartment under the luggage rack, passenger side, main relay also, fuse for the fuel relay 8amp. Electronic Control Unit is also located there.

Could be electrical, Hook up a timing light, three leads: Power, Ground, and one that goes around the wire to #1 cyl. Turn the engine over and see if there's firing. Note: u can check all 4 spark plugs this way.

Fuse lead goes to pin 30 of the fuel relay, u can jump 30 across to 57 and check for the pumps running, if not, change-I suggest both relays, main and fuel run relays. Both pumps get their 12v DC from the fuel run relay, both should be running when you switch ignition switch to on, then a tachymetric signal is fed from the coil to the relay to keep it running.

It's either your heater of the hoses running into and from it

This indicates a fuel vapor leak in the EVAP control system. It means a very small leak has been detected. .The (EVAP) emission control system prevents the escape of fuel vapors from a vehicle's fuel system. Fuel vapors are routed by hoses to a charcoal canister for storage. Later, when the engine is running a purge control valve opens allowing intake vacuum to siphon the fuel vapors into the engine.

A code P0442 most likely means one or more of the following has happened:

• A loose or improperly affixed gas cap
• A non-conforming gas cap (i.e. not factory/original brand)
• A small leak/hole in a fuel vapor hose/tube
• Other small leak in EVAP system
• Faulty vent o-ring seal

With a P0442, the most common repair is to:

• Remove and reinstall the gas cap, clear the codes, and drive for a day and see if the codes come back.
• Otherwise, replace the gas cap, or
• Inspect the EVAP system for cuts/holes in tubes/hoses

Few places to check - rubber hose under air box (requires removing the air box) and hoses connecting to EVAP system under the van on the drivers side.

Short answer, yes. It is to reduce the chances of a vapor lock forming by returning vapor and hot fuel back to the tank and keeping cool fuel circulating through the pump.

it sounds like it is vapor locking. Fuel in the line is vaporizing. fuel pump may be going. check pressure, it should be 40 psi. if 25 or lower, change pump in tank.

I have an 89 one in fuel tank and one under car near differential, drivers side

your evaprative emissions could be purging into the engine at that point too, giving too rich a mixture.

here's what you are referring to:

ISSUE: A reduced power, hesitation, stalling at low vehicle speed, idling and/or a no start condition may occur on some vehicles in hot ambient temperatures and/or high altitudes. In addition, a no start may result while the engine is still hot and the vehicle has been parked for a short period. A stall may also occur when moving the vehicle from idle. This may be caused by a lack of vapor ports in the fuel pump, resulting in a vapor lock condition or internal high wear of the fuel pump components due to tank contaminants.
ACTION: Perform normal diagnostic routines as described in the appropriate year Powertrain Control/Emissions Diagnosis Manual (PC/ED). If the condition still exists after all diagnostics are followed, replace the fuel pump with a new turbine fuel pump. Refer to the following Part Application Chart for correct part usage. Also, replace in-line fuel filter with a new filter (E7DZ-9155-A). The new turbine fuel pump will reduce the possibility of vapor lock in high ambient temperatures. Refer to the appropriate model/year Service Manual for removal and installation procedures.

when you drop the tank by following these directions you will have access to the pump

1989-94 Vehicles
See Figures 1 and 2

1. Disconnect the negative battery cable.
2. Properly relieve the fuel system pressure, as outlined earlier in this section.
3. Raise and safely support the vehicle.

CAUTION Observe all applicable safety precautions when working around gasoline. Do not allow fuel spray or fuel vapors to come in contact with a spark or open flame. Keep a dry chemical (Class B) fire extinguisher near the work area. Never drain or store fuel in an open container due to the possibility of fire or explosion.

1. Use a suitable hand operated pump device to drain the fuel through the filler tube into an approved container.

Before disconnecting any fuel lines from the fuel tank, thoroughly clean around all hose connections.

1. Disconnect the fuel filler vent hose from the fuel tank.
2. Detach the fuel filler hose from the fuel filler inlet tube on the fuel tank. Position the hose out of the way.
3. Disconnect the vapor hose from the front of the fuel tank.
4. Detach the fuel return pipe and position the hose out of the way.
5. Disconnect the two rear rubber exhaust hangers from the rear of the exhaust system and allow the exhaust system to hang down slightly.
6. Unfasten the exhaust shield mounting bolts, then remove the exhaust shield.
7. Support the fuel tank with a suitable jack.
8. Remove the two bolts securing the fuel tank straps, then swing the straps out of the way.
9. Lower the fuel tank enough to disconnect the vapor hose from the fuel sender assembly and the vapor hose from the vapor pipe at the rear of the fuel tank.
10. Detach the electrical connector from the fuel sender assembly and remove the two retaining clips.
11. Remove the tank from the vehicle, slowly to ensure all connections and hoses have been disconnected.

To install:

1. Clean all parts well. Inspect the tank for dents, rust or other damage. On high-mileage vehicles, it may be good practice to remove the fuel pump module and replace the flexible strainer on the fuel pump.
2. Position the fuel tank under the vehicle and raise the tank with a suitable jack.
3. Connect the vapor hose to the fuel tank at the vapor pipe at the rear of the tank and connect the vapor hose to the sender assembly.
4. Attach the electrical connector to the fuel sender assembly.
5. Connect the fuel feed and return lines to the sender assembly.
6. Raise the tank into position into the vehicle and swing the mounting straps under the tank.
7. Install the front fuel tank strap mounting bolts and tighten to 35 ft. lbs. (47 Nm).
8. Remove the jack.
9. Connect the fuel return pipe to the fuel feed pipe.
10. Attach the rear fuel feed pipe to the inlet side of the fuel filter.
11. Tighten the line fittings to 16 ft. lbs. (22 Nm). Make sure to use a back-up wrench to prevent the fuel filter from turning.
12. Connect the vapor hose to the vapor pipe at the front of the vehicle.
13. Attach the fuel filler vent hose to the tank. Connect the fuel filler hose to the fuel filler neck of the tank.
14. Install the exhaust heat shield and the mounting bolts.
15. Position the exhaust system and install the rubber hangers.
16. Carefully lower the vehicle, then refill the fuel system
17. Connect the negative battery cable, then install the fuel filler cap, if not done already.
18. Turn the ignition switchONfor 2 seconds, OFF for 10 seconds, thenONand check for fuel leaks.

Hi,

Why do you want to replace the charcoal purge canister? Are you smelling fuel vapor under the hood?

On a 1986 (this is posted on the 1986 forum), it is held on by a screw (possibly a rivet).

In my opinion, I'd leave the vapor canister alone. If you really want to spend $50 on something, buy new seat covers.
