Will this pump replace the hand bulb pump for priming? I want to be able to prime the carbs without having to hand pump from tank.

This pump output is 3-4 PSI. I guess with a momentary switch it would be possible to use it as a primer pump. This is the very same set-up on my 6.2 liter diesel GM truck, you open the ignition switch and the pump prime the circuit to the injection pump. I hope this answer your question.

I don't think so, I love amazon and most of their products but would not recommend this pump. The first one they sent me had a bad engine so they sent me a second at no cost. The second one they sent has a VERY difficult time priming and I pretty much can't get it to work

If you fill the canister with water first it will primer faster make sure the handle between the 2 hoses is in the open position which is pushed down pump should be plugged in when priming you can find a how to video on YouTube

No, you have to prime it. The priming process is very easy though. I just dip a bucket into the ditch where I'm pumping from and fill up the chamber. I've thought of having another funnel to use when I pour the water in, but it really isn't necessary.

Yes the lines to the primer bulb are two different sizes on my Mac 14". Along with the bulb that had aged out the lines were soft and fell apart in my hands when I tried to remove them. So use new lines - they have been immersed in gas/oil for years.The kit is a generic kit and has two fuel filters, one you won't use. But the kit was still cheaper than a bulb alone at Home Depot. Remove lines carefully and note which fuel line to the bulb goes where. I used a Sharpie to mark them. Or take a photo w/your phone for reference.

Yes. It recommends putting a little vegetable oil into the inlet ( I guess for initial lubrication) then submerge the end and start it up. Even if it looses prime during use, it will self prime and pick back up. This is an awesome little pump. Pumped alot of water from under my house in recent heavy rains

The pump is self priming, be gentle because the handle is delicate but do a good 40 pumps and eventually you will feel resistance. My camper has about 4ft of hose and the sink is about 2 feet above the water connection, if yours is further or higher it might take more. After it is primed it is only a few pumps before the water starts to flow. FYI this pump works but does not give you a ton of water per pump. I just bought a 12volt water pump to hook up, you might want to look into that.

Not by hand pump. I use a small compressor. The size was to small for me...

It is a small, finger operated pump. It sucks gas from the tank and gets it to the carb until the engine gets running. Be sure you didn't install it backwards and if that is OK then the tiny screen filter inside the tiny carb is plugged. Open the carb and get some carb cleaner.

I got this pump for my 1985 40 hp johonson, but the fuel nipple to the carburators was way to small. It is possible to change the nipple. Best regards Kristian Rygh

If pump has to be above the water line I imagine you would need to prime it yourself. Otherwise damage to the unit may occur. I have dealt with trash pumps, sludge pumps and the like at work and most are not self priming. Hope this helps

I'm assuming that your mechanic did not install an in-tank pump. The key is to not expect it to lift the gas very much. Install it as low as possible, in a protected yet accessible place. Help it prime the first time as much as you can -> Full gas tank, purge the downstream line to the carb. I ran it out of gas and with 5 gallons, it primed itself. That's a good sign. These are cheap enough to carry a spare. Always good to reference what carb you have. So the answer is YES. Good luck with the Cadillac.

while the pump is self priming, and will work out of water, I would suggest priming the pump before operating it, for fear that it may overheat. or keep the pump below the water line (out of the tank) to ensure it has water in it no matter what.

No, you have to prime it. It took a couple of tries, but, once it started it pumps strong and never looses prime.

mine doesn't have a primer but a has two barbs one for gas inlet and one for pressure relief. also a fixed gas valve in the carb gas reservoir . some have variable.

You will a pressure tank, I have a small passive tank with bladder, it also helps to keep the pump primed.

This pump is not self priming. Nor is it auto auto turn on/off. If you leave it running dry it'll run and burn out.
