Fuel pump hose fitting
I just replaced our mechanical fuel pump and had a bit of a leaking issue.
The fuel pump has the inlet from the tank on one side (a fixed fitting) and an area for the output (to the carb) that is threaded, which should receive some kind of hose fitting. The old pump had a hose fitting on it that I unscrewed, cleaned, then bolted onto the fuel pump's output. The problem is, it leaks.
I read that teflon tape is a no-no here because it'll dissolve in the fuel and end up in your carb, but the pump leaks when screwed in. I also read somewhere it's a compression fitting and needs to be fairly tight, so I was wondering if there is a torque spec I can use to figure out how tight it should be. I tightened it down pretty good and it stopped the leak, but I'm afraid it'll resurface as everything heats up and vibrates loose.
So should this fitting have some kind of sealant on it? How much torque should be on it?
