I tightened mine when I put on my new pumps until they stopped squirting...and I had to tighten them pretty good!

yeah they do like to squirt dont they,i will make sure its good and tight,plus these are a higher flow fuel pump so more pressure,i think there like at least 75 psi or maybe even 90.

Yeah...the ones they sent me were bigger than originals and noisier. I had to fit them into the bracket...what a pain. But, the pump great! Good luck and no face full of fuel wishes!!!
