660 rhino fuel pump?

Eddyj · Oct 26, 2015

I let my rhino in storage for a couple of month. My fuel pump is not pulling fuel through the filter. I can suck it through with hardly any force. Is there an upgrade? Something I should look for? There is a lot of info about this floating around just looking for some first hand experience. thanks.

My buddy had one he swapped to electric pump no more issues .

You can buy a rebuild kit for the stock pump.

I put one of these on my rhino. I also installed a primer bulb to prime the pump before starting if it has been sitting for a while. (saves the starter and battery)

weller racing makes a nice high flow fuel pump kit.. or buy a stock pump for like 40 bucks and put a priming bulb inline

How would one go about bench testing this pump?
Took it apart seems to be in excellent condition.
It has an in, out, and a "p" port. I'm guessing vacuum off engine.

I can't blow into the "in"
And if I suck on the "p" nothing.

Does the engine have a vacuum that pulses?

Are you ever going to grow up?

I actually typed that out, paused for a second and thought nobody will say anything in "side x side" all the idiots are in general.

it uses the vacuum of the intake.. have you checked to see if theres any trash in the pickup tube or cracks in the plastic fuel pickup?

Eddyj · Nov 7, 2015

Pickup is good. I'm just trying to wrap my head around how it works. With it being a 660 the intake vacuum would surge or pulse. (I would think) but when I put a vacuum to the pump nothing. It doesn't suck anything In the "in" port. I doesn't even flow the vacuum through the pump. Just nothing like sucking on a closed straw.

Re:

Buddy of mine just fixed this issue for a coworker. Said something about pinching off the return line and it would run fine. But I would go on and grab that high flow pump no more than they cost!

I installed one of these on a buddies 700 rhino and he loves it. Starts right up with no problems. Pricey and I think you can get one cheaper if you research it.

I have seen several pick up hoses get soft and collapse

I swapped mine to the cheap parts store variety for carbed engines. Installed a new gas line at the same time and never looked back.

my rhino is doin the same thing now, i replaced the pump and it still does it, if it sits more then a few days it seems to loose prime, im stumped and pissed i might stick a cheapo electric fuel pump on it soon

Eddyj · Jan 26, 2016

I did the 1-4 lb electric fuel pump with new hoses.

The-Boss · Jan 26, 2016

For those that have had pump problems, are there any symptoms other than starting issues? For example, if it does prime will it run normally or loose power under full throttle/backfire when coming off full throttle?

Rockwells607 · Jan 28, 2016

Runs fine. If I run it every Few days it's fine, it happens when it sits over a week

I went on a ride yesterday with the rhino . A few times in the day it dogged out of fuel. Started back up. I'm done messing with this stupid vacuum pump ****. It's getting the electric swap setup as well.
