Anyone familiar with these ??? Looking at replacement for my T2...

Not familiar with that brand but it looks like it would be fine based on looks. Thats easy to say because they all look like the Bosch. Hardto tell what is a knock off and what is not. The price is good enough you could buy 2 and have a backup.

what is the PSI rating on it?

Ricksrb is correct in checking the pressure of the pump. There are two different types of pumps that are common. One is high pressure for port injection and the other is a low pressure for throttle body injection. The low pressure won't work, it's only aboutr 15psi. The low pressure ones are cheaper.

OK... Per customer service:

73psi

38/gph

Didn't have inlet/outlet sizes available to him.... Go figure...

But it looks like I'll be ordering one soon....

Looks same as stock except has threaded outlet instead of barbed end. A 17mm socket took care of the outlet end swap and I'll be damned if it didn't start better than before.

Looks like Kinarfi will have to add this to the parts list.

Put in the second Hayg fuel pump, starts right up, runs fine... Buggy is on trailer this whole time mind you...

Week later the pump is dead just like first one did....

I turn off main elec switch when I shut down buggy each time....

Any thoughts what might be killing my pumps ???

Hello Kurt,

Even tho you have the main elec switch off, still check to see if there is any current still going to the pump. Maybe there is a smash, burnt or crossed wired still sending current to the pump. It could also be a very small current just enough to be there but not enough to turn the blades. Kinarfi, think that could do it?

Check and make sure your ground straps on the trans & engine are clean & tight.

When you say "starts right up, runs fine" that's when you turn the key on, not just hook it up and it does shut down with the key, right? I'm wondering, just how good is a Hayg pump. Is there a possibility that you have water in the gas? Send me you bad one so I can test it, if you want, I won't damage it with out getting back to you for permission and I'll send it back if you want. Do you have the equipment to test for resistance, volts, amps, etc.

The way these pumps work is they move the gas past the armature, the bearings and the brushes, I suggest mounting it vertically so if you DO have water in your fuel, it can drain back out if it's in the pump when you shut down and if there is a strong possibility that you have debris in the tank, maybe a filter ahead of the pump, I prefer and have my filter after the pump in case the pump adds debris to the fuel. As for Rocmoc's suggestions, do check for voltage when off and that the ground wire has a good connection to ground, I doubt that a low voltage would be there via damaged wire, the pump needs too much power for leakage current to damage it.

I lean toward contaminated fuel or jump pumps, but just sitting for a week shouldn't kill even a poorly built pump, and these don't look like junk. How much alcohol is in your fuel? What do the sales people say?

Question: I have been using the barbed output end from the original fuel pump. Yesterday I was looking at it and noticed that it had a check ball with spring type system built into the barb. Closer inspection it looked like it was jammed somewhat and possibly blocking a lot of the flow.

Is this possibly the culprit that creates too much back pressure and smokes the pump?

Is there any consequences if I remove the check ball from the barb end?

Am I totally off base here?

Oh Boy!!! I never should have said anything about not having any problem with my fuel pump, it quit on me yesterday while out in the middle of nowhere. Lucky for me I had a spare one with me. I'am going back to the Bosch pumps no more trying to save a couple of bucks. Personally I will not recommend these pumps, spent the money and get a good one.

Damn, sorry about the jinx....

Kinarfi, you may want to add a caveat to the Hayg listing in parts thread... "Buy at own risk"

With that said, anyone have a Walbro part number that would work?

Their GSL394 is listed as "high pressure" and 190LPH.....

Just trying to see what else is out there besides Bosch.....

      I have an American Landmaster LM500 with an old style snow plow hook-up.  Unfortunately, the mounting bracket broke & I lost the key part where the plow receiver connects to the cross bar with two pins.
      I checked with customer service & they said...

I believe they are sold as a kit though and they are not cheap, part # 15329. I’ve included a photo below since the web store does not have a photo for that part.

      I checked with our parts department and neither the kit or the components are available as that was the older style hook up system. The only option at this point would to have something manufactured. All of our current plows are either dual actuated or winch hookup so we would only have components for those models as of currently.
      In the picture, below, it would be item #5 (the one with the two mounting brackets that hold the pins that the plow mount latches onto) - not the top one in the picture, but the one below t hat.
      I have all the other parts - but the missing part is critical to mounting the plow.
      Does anyone happen to have an old one they could part with - or have an alternative solution?
      The rig wasn't optimal, as you had to use the winch to raise & lower the blade & manually adjust the angle.  It kept falling off when I was plowing snow - as the pins that hold it in only have a groove for a pin clip & they would often get knocked off & then the plow would hang down & you'd loose the pin - then it would get all messed up.
      Thanks in advance for any advice.  I am thinking of going to a welding shop to see if they can create something - but it will still have the same limitations as before - the pins are highly specific and not cheap

      I'm a neophyte in the side-by-side world and am a bit overwhelmed trying to find a used UTV. I want one that can fit the family of four and possibly two dogs plus camping equipment. We will be traveling slowly and cautiously over fire roads and other gravel roads. Just want something that is reliable and able to traverse the backcountry roads.

      I have an ODES Dominator 800 with an AC Delco 51PS battery. I believe the battery is stock.  I was curious if batteries for UTVs were fairly interchangeable as long as they fit in the housing. Or, do I absolutely need to get the exact battery as a replacement?
