Carb fitting..... what do you use? TOOL TIME AT IT'S FINEST!!!

[BIGSHCLUNK]

Over the years I've had this ongoing fuel leak problem. I can never seem to get the fitting on the carb locked down tight enough... Sometimes it's the front other times its the rear. A thinwall socket don't fit right , an open end don't fit right. I just rounded another one, so I'm hoping the new one comes in by tomorrow.  Seems to me the wrench contact area should be twice as wide, then there be no issue....

When I have had these fuel bar issues in the past I had to buy a new fuel bar.

Sometimes the mating just doesn't work no matter what you do, and some folks try to fix it with plumbers tape which is a bad idea.

You could try to use Loctite PST 592 Thread Sealant. Worked a charm on my fuel pump fittings not long ago.

I've had the bar "thought" but my lines are plummed soooooo nice...

Do they make aluminum AN adapters that would work with your existing lines?  The AN adapters have a thicker "hex".

I agree new often solves unsolvable issues some times the line twists as it tightens & puts reverse pressure against the fitting causing it to loosen .

I was hoping somebody had the "right" wrench......

thinwall socket , some had a smaller hex closer to where the line attaches those are easier to tighten
 Thanks for the parts BTW

Neil, glad I could help out. I was gonna throw you an email but mom's in icu and its been a little nuts around here.

[Chryco Psycho]

OK , understandable

Chris , Maybe one of these METRIC Wrenches would do the trick...

  Wade , I'd try just about anything so I don't have to replum....

I have a few of the very old Holley inlet fittings made of steel with a hex for a 3/4" wrench....  Similar to this design

Those look slick with the O ring seal if they will fit a standard Holley bowl....

I found an old sl-cheapo socket in the shop this morning.... it has a date with the shop grinder this afternoon.  fingers crossed....

Use a 6 point socket not a 12 point

[BIGSHCLUNK]

So today was re-tooling day! I ended up buying a socket tho.... wanted 3/8 drive not 1/2. All I could find was 1 12pt but that was ok. After the initial size-up it  was time to fire up the bench grinder.
