Jim,
I reviewed your order sheet and all of my notes on your custom tank. at no time was there ever a discussion or an agreement to supply your fuel sending unit. You also were never charged for the addition of a sending unit to your order. which is why there was never a hole cut in your tank.
I would like you to be pleased with my product and walk away from this a happy customer. Please contact me so that we can straighten this out in a professional manner.
