Rubber grommet doesn't seal well
The rubber grommet that comes with the pump doesn't seal well, after tightening all the way there was a drip around the grommet. As well, because the pump motor sticks out the side, it makes it difficult to install when there are two pumps side by side, such as on a 95 wrangler tank. I ended up buying some stainless steel 5/8" nuts and secured the pumps from the inside to compress the grommet and stop the drips.
