Review on Heating Tank Standard Thread FSS 750 by Oscar Thompson

Used this cap on my auxiliary tank. It was a great idea until I noticed a fuel leak around the lid. As you can see in the photo the middle knot has come undone and is now at the bottom of my tank which I need to fish out. I wrote a letter to Manfu. and called. Waiting for a call back if they will send replacement. UPDATE: Manuf called me back quickly (within minutes) and is sending a replacement. I attribute this to a manufacturing defect that does happen occasionally and as the manufacturer took care of it very quickly I give it 5 stars on all counts. I recommend this seller and product.
