Have 89 Dodge Van V6.
It is just dumping fuel. Seems to have 60# fuel pressure at Throttle Body. My book is unclear, it is eather suspose to be 14.5# or from other sources, it is suspose to be 45-55#
The book speaks of a regulator included with the fuel pump, in the tank. I have the pump out of the tank, but see no signs of a pressure regulator.
Help! This has been driving up the wall. Please help prevent extrodinary fuel wast, and Dodge Van drivers, gone nuts....

 

There is a field service bulletin that Dodge issued on March 1993; 140393 MAR 93 It talks about the Fuel Pump & Filter Replacement Information.

Typically, you can go to your local dealer service parts desk. They will call up the bulliten on the computer screen with all the picture diagrams. For even a small fee, usually, $1 per page, they will print it out for you so you can fix the parts yourself.

Sounds like your return line back to the tank is plugged or kinked? This procedure is for fuel pressure but for a special service bulletin, I copied it so that you could look at the specs and steps involved. Make sure you check out all the fuel lines from front to rear and blow them out if you can.


DIAGNOSIS

Before performing the diagnosis for the above SYMPTOM/ CONDITION, perform the Fuel System Pressure Release Procedure as called out in the "Fuel System" section of the appropriate 1988 or 1989 service manual.

The following procedure will help in diagnosing a ruptured fuel pump supply hose.

1. Disconnect the fuel supply hose from the throttle body.

2. Connect fuel system pressure tester, Miller Tool C-4799-A, to the fuel supply hose.

3. Connect DRB II diagnostic tester to the vehicle connector. Turn the ignition key to the "Run" position. Cycle the DRB II to the Actuate Outputs Test for "Auto Shutdown Relay." This will activate the fuel pump and pressurize the system.

4. The pressure gauge should stabilize at 100 Kpa +/- 7 Kpa (14.5 psi +/- 1 psi).

5. Clamp the fuel return hose shut at the throttle body. The fuel pressure will increase and stabilize at approximately 345 Kpa (50 psi).
6. Turn the ignition to the "OFF" position.

7. If the fuel pressure drops slightly (less than 5 psi) and then stabilizes, the system is operating correctly.

8. If the fuel pressure drops rapidly (to below 10 psi in one minute or less) a leak is present in the fuel supply system.

9. If no leaks are visible between the fuel tank and the throttle body, the problem is most likely a ruptured fuel supply hose at the fuel pump module.

10. Remove the fuel return hose clamp and the fuel pressure tester.


You have an 89 and that has TBI fuel injection. The pressure regulator is up on the throttle body.
