Anyone know if the Wen 56200i 2000 watt generator has the fuel pump like honda does?

[uraceulose]

Will read through this more closely in the next couple hours. Getting dinner ready and doing kids baths etc right now.
Looked at the exploded parts diagrams for the 56200i and can’t find a port listed on there for the intake manifold or manifold vacuum. I may just have to do it like you’re saying twinboat

I believe the small engine fuel pumps use crankcase pressure to operate, not vacuum. They need a pulse from the piston going up and down in there.

Fuel pump on my scooter is located after carb, but before head....and yes, it pulses with pressure

Your Honda generator fuel pump is driven by crankcase pulses.

Take your dipstick out and pull the starter rope. You will see the oil push out and pull in. Scooters, outboard motors, lawn tractor engines, even snow mobiles and jet skis use the pulse from the crank case to stroke the fuel pump diaphragm.

Thanks so much. I was thinking that possibly using the crankcase for vacuum could cause a problem on the upstroke of the piston where it creates pressure rather than vacuum?

I’ll go back through the diagram and see if I can find a spot where I can put a hose barb on and use it to power the fuel pump.

The generator has the style of fuel tank where I can tighten the gas cap down tight and it doesn’t click like an automobile gas cap for ventilation luckily.

Could I just drill and tap into it somewhere and thread a fitting in? I just want to avoid using the gravity method because in my opinion it looks too rigged together to have the auxiliary fuel tank sitting higher than the generator at all times plus it’s more to haul around with a stand of some sort for the aux tank. I may ultimately go that route but trying to avoid it if possible. The more I think about it though, by the time I add the vacuum fuel pump, add the additional fuel lines to feed it and feed both generators when running in parallel..it might look rigged together as well.
No matter what I just want to make it through the night when running AC or heat in 30 degree cold or 90 degree heat. We live in Northern California, lassen national park gets down in the 30’s or below in cold season and lake Shasta is 100+ more than 45 days of the summer every year with lows in the low 80 degree range. Low humidity type of heat but we like to keep it at 70 degrees or so when it’s cold and 72-75 when it’s hot/ac type weather.
To give an idea, we have a 2012 jayco model
1208 pop up that’s about 23 ft long when popped up and all setup, I’ve got a Coleman Mach 15, 15,000 btu AC that will be in tomorrow and want to run it all night if need be with no walking outside to top off with gas.

Found those 50 cc scooter fuel pumps for less than $6.00 shipped on eBay so it’s worth a shot if I can find a spot to tap into for vacuum.

Hey Bob, do you having a diagram for how you wired that remote kill switch? Does is remotely start it as well or just shut off?

[jtyphoid]

Am I understanding correctly that you plan to run a 15000 btu A/C with a single 2000W generator? My experience and all the reports that I have seen are that this is not likely to work.

You will probably be disappointed with an attempt to use an impulse pump on your 4-stroke engine. It doesn't create enough pressure/vacuum pulses to drive a pump. Typically the crankcase is vented to the atmosphere, and no pulses would be available to drive a pump. Impulse pumps are commonly used on 2-stroke engines. Two-stroke engines require a closed crankcase as the incoming fuel charge is passed thru the crankcase and is drawn in by the changing pressure/vacuum pulses generated by the piston's movement. If you require two engines to do your job, you'll need two fuel pumps. I suggest that you go to NAPA and purchase two of their 1.5 to 3.5 psi 12 volt pumps. They operate on low current draw, and are self regulating. You could plumb them directly, one to each carburetor fuel feed nipple. It would be Very Dangerous to attempt to have them fill the onboard generator fuel tanks. The 12 volt pumps will lift fuel a couple of feet, and are self priming. R.T.

No sir. Going to run 2 separate wen 56200i 2000 watt generators in parallel on the occasions that we are boondocking in hot weather with no hookups. 3200 watts continuous im hoping will do it seeing how the ac unit has a built in hard start capacitor.

[uraceulose]

That’s awesome foot dr. I’ll find a way to do that instead and use the generator to power them while hiding the wiring.

[uraceulose]

I’ll post some pictures here soon when I get this all working good!

[jtyphoid]

Two in parallel should do the trick. My two Honda eu2000 don't have any problem running a 15000 btu A/C plus the converter, RV fridge, and lights.

I'll be interested to hear whether you get pulse pumps working on your Wens. I have considered trying to rig up a pulse pump to my Harbor Freight 3500.

I’ll definitely keep you guys updated. Putting the AC on tomorrow and ordering a second generator along with parallel kit this week. It’ll be a couple weeks but one way or another I’m going to get an extra 5-6 gallons of gas hooked up safely and hopefully looking professionally installed to be able to run for a full 12 hours with 2 generators at the same time without refueling.
I also found the little internal thermostat screw to let the ac run it down to about 70-72 degrees on the lowest cool setting before it kicks off on auto
