L-71 Improper fitting, what's wrong with this picture?

[Jacob A.]

Hello,


It has been soo long since I posted, I didn't know that the board had changed to this new format!!! Hello to all of my old friends here, and new ones too!

Just over 4 years still restoring the 57 in my first nut and bolt restoration... and at the same time driving and enjoying my 67 435 Hot Rod. I am putting the #'s matching and correctly dated L-71 in my 67 and I have a question for you guys...

What's wrong with this picture?

This is the fuel pump attached to my 67 L-71, should the fitting at the bottom of the fuel pump come out straight (like it does) our should it be angled towards the block to accept the fuel line at the angle it is coming in?

Thanks in advance, and very best regards
Jacob

I don't know if the L-71 requires one, but they do make 45 degree fittings that work well in situations like this. I looked at Paragon's catalog and can't definitively tell.

Is the fuel pump an AC 40482?

Re: L-71 Improper fitting, what's wrong with this picture?

I hate to ask a silly question, forgive me for it, but is the top of the line connecting to the fuel filter tightened?

If so, it looks like a perfect fit if it's loosened and rotated.

If not, it's likely just variation in the bend angle. My small block was off by about that much as well and required some convincing. I don't think I've bought a set of fuel or brake lines that didn't with Chevelles and Vettes.

Thanks guys,

Joe, I do believe it is the AC 40482.

John, yes it is tightened on the carb side.

Patrick, my engine builder believes the pump I need has a 45degree angle in it?

again thanks guys!
Very Best,

You can't screw the line directly into the fuel pump,it will leak. The pump does not have a tapered seat for the line so you need a brass fitting with a tapered seat.

On some pumps an adapter is required. However, it's not required on this type pump and fitting. The tubing nut on this fitting will thread directly into the fitting on the pump. The flared end of the tubing then seals against the seat in the base of the pump fitting.

Hi Jacob,the fitting should be angled toward the block.Your line is correct, pump is wrong. Thepartsladi sells the 40482 for $30-. Cheers,Graeme.

There was no adapter or 45 degree block originally used for this application. So, one of two things must be true here:

1) The pump has its outlet fitting attached in a manner which differs from original pumps, or;

2) The bends in the tubing are not accurate.

I vote for the latter. I'd loosen it up at the carb end, install it at the pump end, "re-configuring" it (i.e twisting it) to fit, and then tighten up all fittings.

Sorry spoke before I checked. Once I brought the pump up I could see there was a seat in the pump.
edit- Are there enough threads on the line fitting to get deep enough into the pump to seat ? Sure looks like a short fitting on the line.

Graeme is correct. The problem is the pump, not the line.

If I use the small section of the oil pan that I can see in your pic for a reference, it appears that the threaded hole in the fuel pump is facing almost exactly forward, aligning with the C/L of the car/chassis. It's not supposed to.
The fitting should be pointed in, toward the C/L, just about the amount needed to align with the fuel line in your picture.

If the fuel line were bent and attached to the pump as is, I think it would contact the lower rad hose as it passes the front of the fuel pump.

Well, I did some further checking and it turns out that your pump is wrong. Either it's not a 40482 or it's a 40482 that's not manufactured to original configuration.

Attached is a photo of an NOS AC 40482. This, particular, pump is about 25 years old. Note the considerable difference in the angle of the outlet fitting compared to your pump. If you had the correct configuration pump, I think your fuel line will fit fine. In a lot of cases, I have found the pre-bent fuel lines to require some "re-configuration", so I figured it was likely in your case. However, it's NOT the case here; the fuel line appears to be just about right.
