The old swollen gear issue. I have the GPI EZ8 pump and it's locked up again. About 3 years ago I contacted GPI and they played dumb about the problem but sent me a new pump. I thought some people here mentioned bronze or metal replacement gears but maybe my google skills are weak, I can't find anything. What I see available are the same white plastic gears though I seem to have heard the gears have been upgraded and are a dark tan color. I did the sanding once before but didn't last, that was when GPI sent me another pump. Are we stuck with the same crappy parts? Has anyone used a different brand?Thanks,Steve.

I've had to do the sanding thing as well. The best decision I ever made was to avoid putting Ethenol in the Generator tank. Since I've started to use NON Ethenol fuel, I haven't had the problem with the pump sticking. Sorry, I know that wasn't the answer to your question, but something to consider when you do get it back to operational? Good Luck.

EZ-8 or EZ-8RV model pump? Just went through this issue on my 2008 Rage'n. Make sure on the model by checking the serial number tag on the pump.Parts for EZ-8 are easy to find and reasonably priced at multiple places. EZ-8RV parts are available from one retail source. Price seems high in comparison. That source is Affordable RV located in Hesperia, California.http://www.affordablervhd.com If you are a qualified reseller, parts maybe available thru ECI Fuel Systems. ECI is the sole distributor of the Great Plains Industries EZ-8RV model pump.http://www.ecifuelsystems.comBTW, this is the first pump problem since buying the trailer new. The gear problem showed up after a long period of the trailer sitting with a full tank of treated non ethanol fuel. Got the pump to work fine with a little gear sanding. Not sure how long the repair will last so ordered a kit from Affordable RV.

My fuel pump won't work once the sun has been on the fuel station door for a couple of hours but it works fine in the morning when the sun is on the other side. Always.

My pump quit working in the heat, but caught some cold weather in NV and it worked just fine.I have a set of the gray colored gears to install when I get a chance.

Do any of you exercise your generators twice a month including using your pump?

Yes to the gen. No to the pump. It never occurred to me. I'll add that to my maint. list.

there are only 4 in the greater L.A. area! That would be tough to do.
