Hi John,

You mentioned the quantity adjuster electrical plug in this review. There is no socket available to remove the anti-tamper screw for the QA plug since there is no seal available for the plug and no way to install it even if you had removed the screws for it. The wires are soldered to the terminals inside the QA so replacing the seal would be nearly impossible. In almost every single case where the car owner believed he/she needed to replace that seal the real culprit was a leaking top or bottom QA seal that wicked diesel fuel down to the electrical plug. Once the regular QA seals were replaced there was no more leaked fuel. -Jim
