Cool project! I know that the oil pump on my BMW is a chain-driven, positive-displacement gear-pump. My only concern with using an oil pump is that the internals can be prone to rusting, so either you'd want to coat/plate the vanes before use or add coolant to inhibit rust formation, but the oil pump should suit your needs. @Paulster2's suggestion of ...

On most fuel injected cars where you can hear the pump turn on, once the system is up to pressure, the pump won't re-engage until it needs to. One easy way to test this is to turn the car on, but don't start, first thing in the morning. If you hear the pump, good thus far. Next, tap the key over to just barely engage the starter, but not enough to start the ...

Reseal the pump inlet fitting. It lets air in here but will leak very little or no fluid out. It is a short plastic fitting with an o-ring seal on the pump end. In the unlikely case that this does not resolve the symptom, next replace the inlet hose. If it is still doing it after that then reseal the pump. Honda sells all the parts to reseal the pump; the ...

If the pump changed the fuel grade it was pumping you'd see it in the price. My gut sense is that it won't change – too unusual a use case and too much cause for confusion. That said, don't worry about it. If you put in a higher grade than you need, that shouldn't be a problem at all. If you put in a lower grade then you might notice some pinging and it ...

Did you check the user reviews at the source of the fuel pumps. When I replaced mine the two cheapest pumps available had awful reviews. They had a lot of quickly failed comments. Have you inspected the inside of the fuel tank for rust or other contamination? The Explorer has a replaceable pump and a whole assemble available. If you are replacing just the ...

Either the switch is bad or there's a break in the wiring due to corrosion. Gain access to the windshield washer switch connector and check for power on the red wire. If you have power at the switch and not at the pump there's a break in the wiring. If you don't have power on the red wire check the yellow wire for power. If the yellow wire has power replace ...

No, not where I live. The other selections are not available after choosing one and the pump will not change while you are pumping. To change, you would have to complete the current transaction, then start a new one with the grade selection you originally intended.

Power steering is designed to assist mechanical steering via hydraulic pressure supplied by the power steering pump. If your power steering goes out the orientation of the tires can still physically be controlled by the position of the steering wheel, but it will require much more physical force to operate.

I do not think that Vaseline is thick enough and solid enough to withstand the normal pressure involved in the oil pressure system. I think you have a problem with either the new oil pump, or the installation. Many years ago, when I was a young lad, we used to run diesel fuel in the oil pan to clean it out. During a normal oil change, if there was sludge ...

Why do you think that checks the head gasket? Turning the heater on checks the heater and reasonable flow through the cooling system. Good in cold places to have a heater... Pressing the hose finds out if the system is pressurising and can also let you know if the pipes are old and brittle.

To compensate for loss of zero to low speed turning ability, anticipate what direction you will want to move next and point the wheels that way while you are still rolling. Now when you shift from R back to D, for example, to finish backing out of your driveway there is no problem.

The heater not working can be a sign of exhaust gas in the engine cooling system, possibly caused by a leaking cylinder head gasket. Exhaust gas in the heater core will stop heat being transferred, causing a cooler heater. A leaking head gasket can also cause an increase in pressure of the engine cooling system due to exhaust gasses escaping via the gasket....

There's really not much you can do, fuel pumps wear out and they all go eventually. You don't oil them, you don't grease them, they just do their job. The best you can do to extend a fuel pump's life is to make sure the fuel flow is unrestricted: check/change the fuel filter (on a diesel this is often done every service, on a gasoline/petrol car it's every ...

Check your carb. Bad floats. Bad float adjustment. Bad needle and seat. If we are talking Holley 4bbl - look down the throttle bores and see if your see the leak. That will narrow down if its front or rear fuel bowl. On other carbs, if the fuel bowl itself leaks, it can drip straight into motor. Check your fuel pressure - 4psi at idle/no load. On some ...

This is a common problem I had with my 1998 Citroën Xantia, which uses the same sort of washer pump control. I turned out the pump motor was broken, probably a contact problem on the motor commutator. The whole replacement pump costs less than 10 € on the internet (new!). Give it a try. EDIT: Oh, I just noticed I read wrongly: it's NO power delivered when ...

100,000 miles is a "normal" amount of miles for a water pump to break in the sense that it is not unheard of for that to happen. Its difficult to peg a number to how long to expect that a water pump should last because there tends to be a lot of variability. My friend's water pump went out in that ballpark, I'm not sure the exact number of miles but his car ...

This is the sort of thing that you probably can't practically "determine" (as in methodically meter the pins on the device to determine their purpose). So you'll need to find a source of the connection information. One place where you can almost certainly get this information is by looking at the schematic for the vehicle the pump came out of. It will ...

So first off you need to verify fuel pressure like paulster2 said. If you don't have fuel pressure it's time to check the relay wiring. Key On Engine Off At the relay there should be battery voltage (12+V) on pin 5 (orange) If you don't have battery voltage on this wire check the fuses and check the connection to the battery positive terminal. On pin 3 (...

A hydraulic motor/pump off industrial machinery(dumptrucks, etc...) would be another option for a PD oil pump. It would be easier to assemble too since those are designed with common mounts and fittings. They also commonly handle pressures over 2000psi

You could probably also use an electric fuel pump to do this. A rotary vane pump is a positive displacement pump. This type of mechanical pump is used quite often in vehicles. Most can produce anywhere from 45-60psi. There are also low pressure ones which produce about 5-10psi, if you don't need the higher pressure. Using the higher pressure one, you could ...
