Fuel transfer pump


the transfer pump is in the right tank, you can get access to the tank sender/pump units from under the rear seat, i'd suggest checking power to the trans pump and go from there

How do i change a 2004 Lincoln LS fuel pump?


Hi. here's how to change the fuel pump. The actual electric fuel pump is in the tank on the right side. The tank is directly below the rear seat. If you remove the seat bottom you will find a 6 inch or so cover. Under the cover there is a plastic, threaded collar that locks the fuel pump into the tank. The driver's side also has a pump, but it works only my venturi effect from the electric pump on the other side. This pump is used to equalize the fuel level from left to right. The drive shaft tunnel prevents all but the very top of the tank from communicating left to right.

Where is the fuel transfer valve on a dual tank 1993 Ford F150 located?


From what I can find out Ford did not use a fuel transfer valve in 1992. They ran both pumps to a common fuel line and used one way check valves to keep one pump from filling the other tank while keeping the entire fuel system pressurized. Your tank selector switch is actually switching pumps off and on, not a transfer valve. The problem Ford had was the one way valves failing causing one of the tanks to overflow. They have an external one way valve kit to solve this problem, but the valves are about $85.00 each.

My truck 5.9 cumming diesel turbo will not start no pressure out of valve. im thinking its the fuel pump. but want to know does it have just one. some have told me a transfer pump some say it has a low...


It has a fuel transfer pump (low pressure) May be mounted on the engine block next to fuel filter housing or it could be in the tank, depending if it has been updated, Came from factory on block, but later updated to intank> Fuel transfer pump pressure should be at least 8 psi> the injection pump then raises pressure to open injectors. May have to replace transfer pump first or you could possibly have a plugged fuel filter. Do you have any smoke coming from tailpipe while cranking?
Injection pump failure is a common problem. The diafragm breaks inside the injection pump if you run low transfer pump pressure> This causes the timing to be off thus no start. Really best to have it towed to experienced diesl tech. He can get you the right answers rather than just replacing parts, Can get in your wallet real quick,

Need to locate fuel pump on 96 jetta


1996 Volkswagen Jetta 2.0L SFI 4cyl

On a Digifant fuel system, the fuel pump is mounted in a reservoir under the rear of the vehicle. The fuel filter is also in this area. The reservoir holds one liter of fuel and is supplied by a small transfer pump in the tank. The transfer pump can be replaced separately even though they are installed and removed as a unit.

The Motronic system uses two fuel pumps. The first is a small transfer pump to get the fuel out of the tank and the second boosts the fuel pressure to the necessary amount. The transfer pump is located inside the tank and the main pressure pump can be found under the vehicle. This transfer pump is located under the rear seat and is part of the fuel gauge sending unit. The main fuel pump can be found in the reservoir in front of the rear axle beam. There is a check valve inside this pump to maintain pressure in the lines, especially on hot days, to avoid vapor lock. The fuel filter is mounted to the side of the reservoir. This filter has no specified replacement interval and should be good for the entire service life of the vehicle. Whenever the ignition key is in the on position, the pump should run for at least two (2) seconds to pressurize the fuel lines. If the Engine Control Unit (ECM) does not see a signal from the Hall Effect sensor in the distributor it will shut the pump off. If a Hall Effect signal is present, the pump will continue to run as long as a signal is detected. It is this Hall Effect signal that signals the ECM that the engine is rotating therefore indicating that fuel is needed. The pump is operated via a relay that is controlled by the ECM. This relay is located in the vehicles fuse panel. The main contacts of the relay can be jumped to run the pump during testing.

Good luck (rated this help).

99 dodge 2500 5.9 cummins fuel pressure at 3psi


The 3 psi is caused by a failed transfer pump. The problem the loss of could be the VP44 injection pump. This pump should be run at min 7psi. I had the same fuel pressure problem. I replaced my stock transfer pump with a FASS DDRP from www.usdieselparts.com. The stock pump is over $200 to replace and will fail again, sometimes right out of the box. The DDRP will supply about 15psi to the pump and is simple to install. I hope this helps.

How do i fit new fuel pump


the first thing is to figure out which pump... there is a transfer pump (in the fuel tank) and a high pressure pump (under the right rear of the car) get under the car and have someone turn the key to "run"... if you HEAR a humming sound coming from the pump that you can SEE, then it is most likely the transfer pump... if you hear NOTHING then remove the boot on the pump and check for voltage on the positive terminal using a light or a meter. If no voltage then check fuse or the fuel pump relay. (hint: you should hear a "clicking" sound with your ear close to the fuse panel when you turn the key...) VW fuel pumps are really reliable as long as you don't have too much dirt or water in the tank. Eliminate the electrical circuit and high pressure pump as suspects before looking at the transfer pump. Hope this helps.. (oh, and have a clamp handy when changing the high pressure pump to avoid a huge fuel spill!)
