If it’s a pressure tank, you won’t need to siphon it, just use the primer button to get it started. Might take a while though. As for me, I will never siphon gas by mouth again, even if I have to walk out of the dessert! Last year I did that, as I have done for years, but this time I ended up swallowing a 24/1 mix. I seriously considered going to the emergency room. I belched gas for 2 or 3 days and was well lubricated. I do like the jiggle siphons… they work well and are quick.
