Question about Serfas FP50 Floor Pump

Pump seems inefficient, losing air pressure

Pump does not seem to be expelling as much air with each stroke that it used to. Is there a way to do maintenance that will address this problem?

96 toyota tacoma 4 cylinder manual loses power and sputters when the gas is pressed down hard. I can keep it going fine at slower speeds, but when the truck approaches a hill or if I try to accelerate...


It seems to me you may have a very lean air/fuel mixture so when you open the throttle for more air there is no corresponding fuel coming to give you enough power.
My first port of call would be the fuel filter. It may be clogged as you rightly point out. If there is no engine check light on that will iliminate the sensors. I'm sure you would have noticed fuel leaks though what would seem like very high fuel consumption so what remain is the pump.

Some garages may have a fuel pressure gauge to check the pressure but it's a lot cheaper just to replace the fuel pump. The old pump may sometimes have intermittent failure which a pressure gauge may not pick up.

Do you have step by step instructions on how to use floor pump air 2?


Place the end of the air hose nozzle from the pump on the tire valve.
Flip the lever on the side of the air nozzle straight up to lock the nozzle to the tire valve.
Hold the cylinder in one hand. Grab the end of the pump by its handle.
If the handle flips up, flip it up and turn it sideways and let the handle slip into your palm.
The stem of the handle should be extended between your middle finger and your ring finger.
Pull the handle straight out.
You will hear a slight hiss as the air is pulled into the bottom cylinder
and air is expelled out down the hose at the same time.
Push down on the handle to expel the air into the hose from the bottom of the cylinder.
Continue pushing and pulling up on the handle as you hold the pump in your hands until the tire is firm to the touch.
Remove the air nozzle from the tire valve.
Place a tire-pressure gauge on the valve to check the pressure.
Continue pumping and checking the tire to inflate it to the recommended pressure that is marked on the side of the tire.

Losing pressure after about 15 mins pool pump stars really well but then seems to lose pressureleaf catcher before pemp seems to get air in it is this pump or pipes


If the inlet strainer gets air in it, the pump will lose prime. Fill the inlet strainer basket with water, make sure the cover is on air tight. Start the pump and watch the inlet strainer, the amount of air trapped should not increase, if it does, you have a leak somewhere on the piping between the pool and the pump.

Water will not drain out of bottom of dishwasher...... dishes do not seem to be rinsed completeley when cycle finishes


Two issues can be present and might also point to the control board. The pressure pump and the drain pump is not working which has resulted in the inefficiency washing and draining.
so check on the power to these pumps to confirm if the pump is faulty or the controller unit is faulty.

I have brought a petrol pressure washer that says it draws is own water from a static water source (ie barrel) but it needs priming first. what does this mean and how do you do it? i will be using the...


priming means: fill the pump and hose completely with the fluid you intend to pump
start to turn the pump until all air is expelled and liquid comes out of the pump before you put it in the barrel and, start to use it; this must be done; so, that air is removed because the air can not be pumped and will prevent the pump from working.

Bissel pro heat cleaner won't expell water -- seems no suction


The reason that it won't expel water is because your pump belt is stretched and worn. You need to replace that belt, it is pretty easy. Here is the belt you need:

Water pump 1989 Mercury 45hp


Definitely it should push out water all the time. It probably looks like more with the hose pressure feeding the motor. You should have water discharge in the lake at idle.
