V-band clamp for GM fuel pump
I have the Bosch 67317 fuel pump and was looking how the V-band clamp works with our tank.
Our tank lip where the V-band clamp mounts has a taper (wider near the tank, getting narrow at the top). So the V-band clamp will tend to pull up as it is tightened until it hits the little lip at the top of the tank opening.
My fuel pump thickness with the gasket non-compressed is 0.275".
My measurement with the V-band clamp (DMCH part) with the clamp lifted to the tank lip is 0.43". So if you press down on the pump as you tighten the clamp, that clamp will try to lift because of the taper. So have people had any leaking when you overfill the tank?
By the way my pump plate is 4.58" dia. and the gasket which came with the pump is a perfect fit for our tank. I was wondering if the DMC pump thickness is more than mine.
V-band clamps can be bought with that "V" thickness less then the DMC part. Was wondering if I should get another V-band clamp with that thickness (known as INSERT APEX WIDTH).
What V-band clamp part numbers have you users that bought for your GM fuel pumps?
