Title: Tool for this type of flare
Post by: tmsmini on March 12, 2022, 08:11:45 PM
It is not really a flare, but more an acorn to keep a hose on.
I have a Mastercool flare tool and I thought maybe forming a flare partway might come close.

This is a fuel line from a 327 Holley, but I want to do the same on the Mini

Seems like a partial or bubble flare would work?

I have done it before with just the first step of the double flare or a bubble flare, not perfect but is more secure than just clamping to flat tube. I have never seen a tool specifically for those fuel line flares but maybe one exists?

They do exist - sort of - it rolls a bead on the end of the tube......the good ones are spendy and it's hard to find one for 5/16 or 1/4" tubing.....tho they are out there.

Just a standard flare tool should give you the lip you need to ensure a hose doesn't slip off.

That on is a little out of my price range.
Tests with partial flares are mixed so far, a little more practice on when to stop

This is the best I could do. There was a GM specific fuel line flare I thought would work, but it was not any better

If the goal is just to prevent hose slippage, that will do it. No way a hose clamp is jumping that lip.

Practiced a little more on the GM connector flare.
I am trying to plumb the engine test stand for an external pump and swirl pot to use with injection fuel pressure. The swirl pot came with flared fittings and the fuel filter has stubs for its fittings that need to be flared.

How about putting a regular flared fitting on the tubing and then using a hose barb to flare fitting on the end?

You can also get fairly cheap tools to do the 37 degree flare for AN fittings if you wanted to go the route of being able to fasten it all together that way.

Some great suggestions, thank you.
I have AN fittings on the car, but thought I could skip them for the test stand, maybe I will rethink that.

You need the Graham Tool Co beading tool. This bead was done in seamless stainless tubing.

The small one does 1/4 an 5/16
Maybe if I hit the lottery...

Jeez louise, $200......

I'd be all over one of those if I could get one for $50 or so......

That is a slick tool tho, and it sure does a nice job.  77.gif

Practice makes better, not perfect but functional
