archeman Posted February 23, 2022 Share Posted February 23, 2022 I think that these pumps are good for about 5 years before the ethanol in the gas (10% where I live) eats the rubber tubing away. It seems easy enough to me to replace the rubber tubing with material that can stand up to the awful gasoline of the modern world. Does anyone have a solution or can post a link that I can order a few feet to replace all the tubing in my two tanks. Link to comment Share on other sites More sharing options...
85lebaront2 Posted February 23, 2022 Share Posted February 23, 2022 I believe it is SAE J70R9 I used on my LeBaron convertible. I will have to look and let you know. Link to comment Share on other sites More sharing options...

I found this link on Amazon but it always helps to have confirmation from others who have had success: https://www.amazon.com/True-Blue-Ethanol-Resistant-Chainsaw/dp/B08DRPC58P The tubing above is for 2 stroke motors but it likely will work for my truck. My truck is NOT my daily driver so it often waits for a 'truck' mission to get on the road. 2 strokes often sit idle for long periods between use. I read a thread in this forum about the problems with sending units not matching well with the fuel gage and I definitely have that problem too with my new pump so if I'm going to have to wrestle the tank down again I would rather just fix the old pump and keep this new one as an emergency spare.

We have non-ethanol gasoline available here in Texas. It costs 40 cents a gallon more, but we don't get all the ethanol problems in our carbs especially small engines like zero turns. Our chainsaws run on synthetic fuel. Have not had to touch a carb since we started doing this method. FYI Link to comment Share on other sites More sharing options...
