Does anyone know off-hand what the fitting size/type is for the threaded fuel line fitting that goes into the OEM gas tank? 

I need to repalce the OEM fuel line and buying a pre-bent fuel line is pricey and the line seems pretty simple except for the fitting going to the tank.  I'm looking at some of the tubing from Summit Racing or Russel, but my head is starting to spin when it comes to keeping track of the different flare angles (russel tube says 37 degree flare) and the converting between NPT fitting and -AN fittings.  I can figure out if I know what I'm starting with and the fitting that seems to matter is the one going into the fuel tank.  From there I can figure what adapers etc I need to get going and mate up with the new line.  Of course after all the adapters and flaring tools probably would be close to the price of a pre-bent line from in-line tube.

What is the stock fuel line diameter?...it seemed to be 1/4 inch but I was meauring with a tape measure...not the most accurate.

Nate , on my 58 I bought a 25' roll of 3/8 tubing from autozone. It came with a protective coating and bends to shape pretty easy. For tight radius I used a small tubing bender. You can get one at the Chinese tool outlet cheap. As you remove the old tubing you'll see where the new one goes. At each end I connect to a nipple with a high quality rubber hose and clamps. Make sure the tank is clean or your troubles have just began.





thanks, Mark

Nate:

You didn't state what your tank is, but the stock '55 tank has a 5/16" inverted flare connection.

Thanks guys! Hoosier, my tank is a stock OEM tank (not sure how else to identify it) for a 56 customline.  Knowing what it is for your 55 I can look at part numbers and see if they are the same tank.

I'll have to look and see what an "inverted" flare is...do I need an inverted flare tool if I were going to try and duplicate that fitting?  Can I even do that with some of the aluminum tube that frankenstien mentioned?

The other Idea I had was to just use the OEM section of tube withe the fitting and be sure I clean it out, then juse use some rubber hose and hose clamp to hook it to my new tube.

Frankenstien...my tank is brand new!! So it is clean clean clean!!

Ok...just had an "ah-ha" moment.  Assuming I buy the correct size fuel line tubing (5/16" I think) I can just use the fitting from the existing OEM line...just cut the OEM line and slide off the factory fitting.  Then slide it on the new tube and flare the new tube, 45 degrees..with a double flare tool!  It'll be like new!

right?  Or will a normal 45 deg double flare tool not work on an "inverted flare" fitting?   Ok...back to Wikipedia to read about what exactly is an "inverted" flare.

Nate:

The double flare 45 degree is exactly what you need.  I meant to type '56 in my previous post, the tube sizes are the same for both, 5/16".  You can re-use your original nut as you stated.

Nate: A note on "pre bent" gas lines. A buddy bought one for his 56 tudor sedan. He says they will only fit as original if you are doing a body off resto. So go with the coil method or use straights with fittings & bend as needed...

Thanks guys!  ...momentum is building!  I see the light...I've got shopping list (and it isn't that expensive) and a clear path towards success.   Assuming my brakes aren't terrible I could be driving this thing by the time the tulips are in bloom!

She is running with her own on-board fuel supply!!  I finished the gas line this weekend, the aluminum 5/16 line from summit was great, very flexible I was able to snake it and bend it along the OEM fuel-line path.  My harbor-freight double-flare tool was smooth!

I also bought new 215/75 R15 tires, they're all mounted and ready to go on the car.  Just need to bleed the brakes, bolt on the wheels and cautiously put her in first gear and let out the clutch!!  I'd be at the garage right now if I could. I can't wait to drive her.....but I have to work to fund these things and can't afford vacation time.

I'm amazed at how much of everything works on this car.  It looks like it has been sitting in a barn for 40 years, but all the lights, gauges, and horn (such a cool horn!) all work!

I noticed that there appears to be no fuel filter on the car.  Does anyone add one?  If so where and what type?
