Question

Hi. I need to know where the fuel pressure regulator is located on a 1988 Dodge Dakota Sport with a 3.9 L V-6 Engine that has an automatic transmission. 2 wheel drive. I believe it is near the carburetor but I am not sure. Any help or suggestions will be appreciated. Thanks for the help.

in fact that the gas rigidity regulator could be everywhere alongside the gas line, in spite of the undeniable fact that that's oftentimes close to the gas injectors the place the rigidity needs to be precisely controlled. Like something which you fairly choose for to regulate, nearer is extra efficient. Throttle physique injection, which combines gas and air like a carburetor, has the rigidity regulator fastened to the throttle physique between the gas line and the injectors which spray gas into the air because it passes contained in direction of the venturi section, the narrow portion of the barell, purely like in a carburetor. From there the gas-air blend passes contained in direction of the intake manifold, dividing into passages best to the guy cylinders the place the mixture is compressed before that's ignited by the spark plugs. This spark motives an explosion which forces each piston returned by using its cylinder, turning the crankshaft by way of connecting rods that are linked to the two, piston and crankshaft. Port gas injection sprays gas into the air blend on the intake port because it enters the cylinder; hence, each cylinder needs its own injector or injectors. this methodology is unquestionably pointed out by a gas rail, a tube that runs alongside the line of gas injectors with a separate branch feeding each. The rigidity regulator is linked to the gas rail, close to the injectors, the place it may administration the gas rigidity because it is going into the injectors. The gas rigidity regulator is a small cylinder with a rubber vacuum hose on suitable and a return drain tube on the backside. that's a detachable, separately replaceable, section, with a around diaphram interior, which acts as a valve that enables some gas to bypass into the drain line while gas rigidity is above the mandatory putting and overcomes the vacuum on the diaphram. that's not placed far from the section the place the rigidity needs to be regulated, no longer on the gas pump or the inline gas filter out; which could be like attempting tocontinual a motor vehicle from the returned seat, stressful for a common man or woman to do. despite the fact that this regulator is a administration gadget, it can not function suitable and not applying a vacuum, as properly as an undamaged diaphram. that's a mechanical, no longer an digital, administration gadget.

The fuel pressure regulator is the fuel filter. Note the extra line returning to the tank.
