Al,
The photos show an original routing for the gas line. Too many have been replaced and the replacement does not go under the outboard bottom side of the starter and then up to the fuel pump. Instead it was run across the engine pan. Or uses a gentle bend to go over the cross member and then angle toward the fuel pump. As you can see there is no interference with the shock linkage.

Hi Chipper, I'm now confused. Are my photos correct? I really do not think this car was ever touched. Thanks, Al W.
Is this the correct way.

Excellent photos Al, and it sure look original end to end. At this point I will try to follow yours unless something more compelling comes along. The manner in which it crosses front cross member and follows profile of starter looks very convincing to me. I looked at running it under the cross member to engine pan and then turning it, but that route does not leave a means of fastening it to chassis, so your route looks more likely. I am wondering what the clip on top of cross member was for? Too bad your subject car is in such rough shape!

Yes Al your photos show a gas line that is in the original position and has the original bends.

Guess my comment on what is typically found with replacements confused you. Sorry I was not more clear.

The clamp for the gas line is on the back side of the cross member nearest to the starter. It is hard to see in the photos as it is in partial shadow and partly covered with stuff. Can't remember what goes in the clip on top. Brain is fried after sitting at keyboard all day. Working on Tour stuff.

On the first picture of the fule line.Does the fuel line run under the shock absorber and behind the front spring mount. The pictures that I took of my car on dissasembly my line went around the rear spring mount .

The clip on top of the cross member is for the positive battery cable.

By the way, the routing of the fuel line is correct as shown in the close up photo of the starter and the fuel line at the beginning of this thread. The fuel line goes across the back of the cross member over to the bell housing, and it goes over the cross member then runs under the starter near the edge of the engine block and is in a direct line with the fuel pump. The fuel line bends vertically in front of the starter and then bends horizontally and goes directly to the inlet on the fuel pump. There is a clip on the back of the cross member for the fuel line.

So maybe mines a bit different on a 32.I think I would have enough room to get the line through under the rear shock absorber and it might get through under the rear spring mount.My battery box brackets are tight to the cruch of the frame but there might be enough room in there as well.The front looks very correct and very simmilar to a 32.

1931 and 1932 had the same gas line routing from the gas tank to the fuel pump. The line from the fuel pump to the carburetor is very different.

With respect to the rear spring mount, the gas line originally was a one piece line, went under the rear shock, hugged along steel frame (held with clips), and simply bowed out around the spring mount area before returning to frame and more clips, behind battery box etc. When I replaced mine, I did it in 2 pieces with a union coupling just ahead of the spring mount. That enabled me to place the rear section of the line through the space at inner edge of spring mount and completely out of sight and out of harm's way. I posted photos a while back (06 28 12) in "members photo section".

Everyone knows that the Filling Station has correct fuel lines for a 31 and 32? I supplied my original lines for them to copy.

I didn't know that!

For me Im sure the shipping alone would cost more than the line. Besides what fun do you get by simpley opening a box and bolting the part on. I think Ill add an inline filter before the fuel pump probably in the frame after the spring mount and before the battery box.

I was thinking of adding an AC glass bowl type filter right at the tank when I re do the fuel line on my 31. Any cons on that idea?

I was thinking of using a metal filter. I always worrie about the sedement bowl breaking.

Why add a filter to the system which you don't need? The AC GF-48 filter paper works in the 29 to 33 fuel pump and 35 to 36 fuel pump without a problem and your not adding any fitting for air to get into the system.

We talked about this some time ago on here....if you have a thin wall glass bowl you use one filter and a thick glass bowl you use a different one. They would great and you can get them from the Filling Station and they can't been seen....unless you have a Judge like me that knows what he is looking for.

I added a clear polycrylic inline filter that has a washable screen. I like it because you can see the sediment when it's there and it can be disassembled, cleaned and reinstalled. No need to carry replacement filters or guess if there is sediment causing fuel starvation.I did place it along the frame ahead of the spring brkt, but I don't show the car I'm not concerned if someone wants to crawl under the car and sees it. It will not break like a glass bowl.

Bruce, good idea on using the pump bowl but the AC GF-124's(GF-48 element) I have will not fit the 31 bowl, they are too big. It must be the other number, do you recall the part number?

Thanks

Dave

Update on the GF-124's. The new ones that are paper do not fit. My old GF-124 AC's with the foam type element that is tapered do fit but I would be afraid to use them with todays gas.

n006840. Where did you find that type of fuel filter. I could not locate one local.

I got it at a local Parts Plus auto supply company. I can check to see if I can get a manufacturers number if you want. Also check the internet for ( MR Gasket 9747 ) which I believe is the unit I have.

Thank You
I will look today and see what information I can find. I will let you know how I make out

The supplier I used said his product was made by Dorman and it is their part number 55241.

Hi All,

Here is a copy of my post from about 2 years ago. There are two paper filters which work great in our original fuel pumps so you don't need to cut the lines or anything. Please let me know if you have any questions. Steve Kassis from the Filling Station runs his cars with one of these all the time.

Bruce


Dan is right, the paper filter from the Filling Station works great. I've used one for years and have not had a problem. Now the Screen works ok if you have a really clean tank, on the early 6 tour I have given out more filters to people who have dirty tanks and the screen will not stop some of the dirt when the paper filter will.

If you have a NAPA near you, you can get one of these filters if you want. There are two different filters which will work. The one that the Filling Station has is smaller and will work with the bowl which has a thicker side wall I think that is AC GF-149. Then you can also use AC GF-124 which will work with the thin wall bowl. The NAPA number for this filter is 3034.

The one thing that I would not do is cut the line, you can never put it back with out installing a complete new line.
