First Guess: Cracked flare on the end of the tubing. You might get by with replacing the tubing.

If it's not a cracked flare, then the flare and flare seat must be distorted. You'll need both the tubing and the brass block.

so if i replace the brass block, what's the chance of me messing up the connection between the saucer thing (aka pulsation dampener?) and that brass block?

I am thinking it's just a basic npt fitting there like ontop of the fuel pump where the brass block screws into.

if i screw that connection up, and it leaks too, i may end up having to replace it, which seems hard to do as i cannot find it anywhere so far..

or am i worrying about nothing regarding the brass block and saucer interface?

Well went to my local parts place to get a replacement fuel line and fittings. He did not have the brass block but could have made an adapter with a couple extra joints. He then said that I could delete the saucer thing after he saw it and go to rubber hose. So I got some hose and a elbow with a nipple and installed. Fired up and drove for about 10 minutes. No leaks and running great.

next is motor mounts as she has a good vibration in cabin at idle and moving. It goes away at higher rpms. Will research that and see if that's something I can do or not.

Thanks! It was my first ever fuel pump. Mechanical or otherwise.

There's a reason that GM didn't use rubber hose on the pressure side of the fuel pump. GM always used metal tubing.

well somebody got to it before me as there was rubber hose 1/2 way between the flared ends of the original fittings. And it was like that for years it looked like based on hose condition. So far so good.

Still no reason to not bend and flare a replacement tube. I don't trust pre-bent tubes to actually fit. I bent a pump-to-carb tube for "Doctor K" the Comfortron guy's 70 Toro when he visited me. Took about an hour to fabricate and install--maybe a little less.
