As I have said many times I have only had ONE leak over the last two decades. The one in the Savoy has been there for well over a decade now never an issue from it under the car getting pelted with crap on every burnout. These days we use Weldon stuff, just better products IMO but never had any real issues with Magnafuel pumps either. Have had some regulator problems over the years with them. That was what started the switch to Weldon was the regulators.
