Six Barrell Carb Question

[clazar]

1970 440 six barrell. I needed to take the center carb off last nite. Of course one of the fuel inlets was turning when I was removing the fuel line. It's tough to get a wrench solidly on the inlet. Does Holley or someone make a tool for that occasion.

I did what @Mattax did with a box end but it can still be a bit tough while on the car......

Flare Wrench for Holley Inlets

Years ago I saw a fuel bowl inlet wrench in a catalog that was a stamping. I wish I bought it. Never seen one since. One of the most annoying things with the stock inlets on 4150/60 carbs is having the inverted flare adapter move when removing the inverted flare nuts on the fuel lines. Yet...

I would disconnect it from the Tee instead.

I've always been able to remove the center carb without any difficulties...BUT... proper tools sre required. ABSOLUTELY USE A FLARE NUT WRENCH (on the tubing nut).....AND a 11/16" (MAC TOOLS) 4 sided open end wrench....its thin enough to fit the Holley hex head fuel bowl inlet fitting, without rounding off the corners. ALWAYS replace the fiber gasket under the bowl inlet fitting and DO NOT OVER TIGHTEN....bowl threads are delicate.......and....when reassembling, back up the bowl fitting with the 11/16" wrench when tightening the fuel line nut....with a FLARE NUT WRENCH......use NO tape or thread dope on the flsred connection.....assembly dry....in spite of what others profess......just my opinion of course......

That’s kool! But I’d put a piece of electrical tape on the tip.

this!!!!!!!!! once the flare nut/bowl fitting is sealed up never touch it. original 6pak bowl fittings had a hex on the center and rear carb to tighten the fitting up but jacking with the fitting after everything is sealed up is a can of worms.

^^^ glad you mentioned that

Do you have a Mac tools part number for that 11/16 wrench?

The S-141 comes up blank on a search at MAC.

SAE Angle Wrenches

Open end set at 60°, the other at 15° .Both ends are the same size; therefore one wrench can be used in different directions for better leverage and has four different turning angles per wrench .Excellent on jam nuts, aircraft, and close clearance applications

That's a thin one pictured. The regular angle wrenches are quite thick and may not fit

I just took an old regular wrench and ground it down flatter and thinner so that it fit works perfectly

Pics of my tool, works great.
I will say I used to play around with these things back in the day, as Mentioned by R J
if you crack open the big nut replace the gasket but do not over tighten!
Hold it with the tool when you tighten the flair nut.
No big deal.
I tuned my carbs for the last time around 10 years ago... starts and runs like a dream to this day..

Good advice from Bob and others above. ALWAYS use two wenches - " back up" the fitting. This is actually standard practice.
