Fuel line hose 1962 Coupe DeVille

[62devillecoupe]

I am looking to replace the fuel line hose that runs from the fuel pump down to the metal fuel line under the engine.

Is there a specific brand that anyone recommends?

Also, what side (outside and inside diameter) should I be looking for? I know I can take the hose off to measure or take a piece with me to the auto parts store, but I’d rather buy the new hose ahead of time.

Thanks,
John

Caddy Daddy has it with correct fittings

John,
On a 1960 Cadillac, the supply line (tank to fuel pump) is 5/16 and the return is 1/4 (ac cars).   I guessing that your car is the same.   SHalver #24920

   my 62 with Air  has a 5/6 ID fuel line to the pump and a 1/4 ID line from the fuel filter to the vent return line . If you ask for
  fuel line it usually is clearly marked as such

Thanks.

My car doesn’t haven’t air so I don’t have the return line.

The fuel line hose I am looking to replace is between the pump and the rigid line that runs from under the engine back to the tank.

If you’re looking for this line - Caddy Daddy

62's don't have threaded fittings.  Just a corbin clamp at each end is all you need.

[Jon S]

This is what Caddy Daddy shows. What is on OP’s car?

[quadfins]

Don't know, but that part is not OEM for that location on a '62.

Dan is correct.

I’ve never seen anything like that in in that location on a ‘59-‘61, either. There’s just a piece of hose with clamps, as Dan describes.

[Jon S]

 Well I don’t claim to be an expert on 1962s however I did Google quite a few 1962 engine pictures and all of them have that style hose so I would be interested in seeing what kind of a fuel line you believe belongs on there. I thought all the 1957 through 1962 used the same set up.

[quadfins]

It is just a piece of rubber hose, with a spring ring clamp on either end. The fuel pump has a flanged fitting to accept the hose and clamp - no threads -and the metal fuel line is the same.

[Jon S]

Thank you. A lot simplier to change then the threaded ones used in 1958!

Jus stirring the pot.   
Does the '62 fuel line have a barb on the end to secure a hose clamp?

OR is it flush cut?   Flush cut wouldn't be a normal SAE fuel hose connection.   
Typical for auto fuel flex hose clamps are barbed ends.     
If hard line has a flare fitting end, then a brass adapter to either a hose barb or screw end hose would be correct.   The '58 has screw end hose, and I think it's common this way in that 365/390 genre, but they did completely change the motor in '62.   I'm sitting here without that parts list handy.   
Over the years, I suspect, people rather than pony up for the expensive hose, cut the flare end off the line and replaced with a piece of hose.   But I reserve right to be wrong.   

[quadfins]

Just a single raised ridge around the end, enough to provide a little better grip for the hose and clamp, so they would not slip off. Not really "barbed", as I would interpret that as having several ridges. But not flat, either.

Engine design changed in '63. 60 - 62 are virtually identical. '59 had a different oil filter and accessory brackets.

My 1962 has a regular piece of fuel line hose with a wire clamp onto the fuel pump.

I just want to replace it and wasn’t sure on the correct size.

Here is a pic of what mine looks like. For some reason my uncle, who bought this Caddy when it was new decided to replace the hose and put a piece of copper pipe in the area where it rests against the clamp near the belt. I don’t know why he did this. Also he painted the hose which is odd. Anyhow, it should be replaced in my opinion.

[35-709]

Ray Richards had the answer.  Just take the hose off and take it to the auto parts store, there should be no problem getting the correct size.

[Jon S]

Well I have to tell you that’s a much simpler set up that I have on my 1958.  In order to change the fuel pump  I have to remove that line and disconnect the double nut connection below the generator which is quite an ordeal (I have done several times).

Ray Richards is correct in that it is a 5/16 fuel hose that can be purchased at any auto parts store.  It comes on a spool and is sold by the inch in whatever length you want.  Be sure to get hose that is for ethanol gas, if that is what you are using.  I would eliminate the copper tubing, as it is just one more place for a possible leak, and is not original.  The hose was probably originally secured to the front of the engine by a loop clamp like this (it is on my 1959 engine):

Unless you are going for OEM authenticity, the small worm gear clamps are OK, but if you want the original clamps, they are the wire corbin clamps, such as these:
