LOVE THE PRODUCT. ALSO WAS DEALING WITH A SALES PERSON THAT IS NO LONGER WITH COMPANY, CUSTOMER SERVICE WAS QUICK TO INFORM US AND WAS QUICK TO HELP WITH OUR ORDER THANKS.
these kits, i strip of the nuts, and sell the lines alone. even then i beat the others in price and have the perk of additional sales of the nuts separately
shipping was not that great, fittings were removed from sealed kits to fit in a bag, some tubing got bent in shipping, will have to fix before use. This could have been prevented by putting it in a box!
Received what i ordered, and shipping seemed timely too.
So far everything seems good with 4life time lines
I just wish there were metal fuel lines, or at least pre - formed ones for the plastic offerings
