I need a fuel pump for 632 bobcat with 1.6L industrial ford engine engine model #2274E

Likely to be the glow plugs or the diesel pump.

Probably the same as a car and needs a sealed system for Pump, Emissions and Evap.

Fixya isn't really a heavy plant site. There must be better forums.

I can't find a 323 video, just other bobcat videos related to tank removal such as: https://www.youtube.com/watch?v=1t0JkCTePtE

With at least some bobcats it is not possible to remove the fuel tank without removing the engine. Outside my realm of expertiese but at least I can point you to repair manuals. No info on reliablitiy of the sites but the 2nd one strikes me as more mainstream.

it could be pump. ive also found that the pickup tube breaks off causing the pump to suck air. also hows the fuel filter? could be a problem also

either on the pump or fuel filter case there will be a small hand pump that you pump the fuel to the fuel pump. there are small bleed screws at the filter or on the pump that you open partially and as you pump you will see air and fuel come out. keep pumping until you get solid fuel then close off. The pump may be round so you will have to unscrew the top and that will allow the pump plunger to move . When finished do up the plunger again. Once the air is out of the system, crack the injector line nuts at each injector and crank the engine until there are drops of fuel at the nut, tighten up the nuts and it should start.

The best place to get this will be from a ford tractor dealer or from a tractor manual.The good thing about this is that most tractor engine ran similar fuel system set up so if you another tractor of the same age and HP you will probable be able to see how things are set out

From 1981 on, ford and the rest of the auto industry was mandated by the government to use a 17 digit number visible through the windshield, this number contains the vehicle and engine identification codes.

Electric Fuel Pump - Removal & Installation

Two electric pumps are used on fuel injected models; a low pressure boost pump mounted in the fuel tank and a high pressure pump mounted on the vehicle frame. Some models equipped with the 8-460 (7.5L) carbureted engines use a single low pressure pump mounted in the fuel tank.On injected models the low pressure pump is used to provide pressurized fuel to the inlet of the high pressure pump and helps prevent noise and heating problems. The externally mounted high pressure pump is capable of supplying 15.9 gallons of fuel an hour. System pressure is controlled by a pressure regulator mounted on the engine.
With internal fuel tank mounted pumps tank removal is required when servicing the pump. Frame mounted models can be accessed from under the vehicle. Prior to servicing release system pressure (see Fuel Supply Manifold details). Disconnect the negative battery cable prior to pump removal.

I hope help you with this (remember rated this help) Good luck.
