Holley 1850 fuel transfer tube seals??
Well thats what I was thinking, the Holley kit i got fits a multitude of applications and it came with the seals AND o-rings, i remember I couldn't get the seals to fit the first time but I thought I'd try again, i mean I'm a 210 pound guy and I used all the force I had pushing against that bowl, I honestly thought the tube was going to bend, if you find out I'd like to know but for now the o-rings are in.
