Rtv 500 not starting?

buckmaster27012 · Sep 15, 2016

well comes out cannot just buy the fuel filter alone. have to buy pump and all at $180. so i cleaned on it the best i could to see how long it will last. no good way to do it that i could see. does anyone have any suggestions on how they cleaned one? i used air and blew it out. is there any info out on the vent lines off the gas tank and the carbon box with the three way valve, i was tracing it all down and just trying to figure out the purpose of it all. thanks

same issue is going on again with not getting fuel. its probably the pump filter plugged again. has anyone ever found a replacement filter for these? or I may try cut it off and putting in an inline filter after the pump just to see how long it last. I'm sure there is a reason for filter on bottom of pump but hadn't got a good answer yet. thanks

dont see any black smoke. may drain gas tank and put in non ethanol see how it does. the funny things is each time it has happened it been sitting out in the sun and seems like something getting hot, but not sure what. but it still cranks a little later and it not moved out of sun.

My refusal to start, like yours, was when the engine was hot. (See Post #4). I think it is old fuel, with 10% + ethanol fuel staling fairly fast. Since I changed to 100% "marine" gas I have not had a recurrence. I buy Chevron marine gas four gallons at a time, which is a two week supply for me.

How old is your fuel in your fuel can(s)?

How old is the fuel in your RTV500 tank?

Do you exhaust all fuel in the RTV500 tank before adding fresh gas or is the RTV500 fuel a changing blend of old and new fuel?

If you are not going to scrub out your RTV500 tank I suggest adding SEAFOAM to your fresh, non-ethanol fuel.

Mine had been sitting all day before I tried to crank it. The fuel may be a month old but I always add Star-tron to each tank. I put Seafoam on it about twice a year. I normally top my RTV tank off about once a month never try to let it run empty and its probably 1/4 tank left when I do that. It has cranked fine since last issue so we shall see what next few times bring. Always happens when I'm in a hurry and need to use it.
