Can’t help you by this weekend, but let me know if you want me to pick you one up this weekend. I have a cabin in Cumberland, Wi. (Ardisam’s HQ). They have a store (Country Store) that repairs Eskimo’s and has gas caps. I’ll be going up tomorrow but won’t be coming home until Sunday. I work in Eagan and could get it to you early next week. Let me know if your interested. Otherwise here is a link to Ardisam. If you search for gas cap, you should be able to order on-line. Not sure if you could get it sent priority by this weekend though. Otherwise you could try calling them. Good luck. I’ve had to replace my gas cap a couple times too (leaked). How hard can it be to invent a stupid gas cap that won’t leak?
