Carl 61 Fleetwood Phyllis

[Clewisiii]

From this photo it looks like it comes in along the oil pan. But I just do not know how it flows under the engine.

[Clewisiii]

I decided this is how the lines route on the front of the engine.

The supply line across the front of the AC generator bracket, and the return line between the two.

They go below the engine and route near the trans cooler lines. But I have not determined how the metal lines route under the engine and where they meet the rubber lines.

I had a 3/8 line for fuel and a 1/4 inch line for return. But I could turn the rubber line on the fuel pump by hand while it was clamped on. I switched it out for a 5/16 line that feels much more secure. But I dont know if that is correct and am keeping it yet.

[The Tassie Devil(le)]

I would have thought that 3/8" lines would have been too large for the non-performance cars back in the day.

It is a little annoying because I have a small supply of the original color coded clamps that my grandpa stole from the GM plant decades ago. But I do not have one to fit a 5/16 line.

Guess Gpa was taking a queue from Johnny Cash?  GM wouldn't miss just one little piece! Ha!

It's interesting seeing the minor differences between your 61 and mine.  Mine is a CA original car and I never gave much thought to the idea that they were different than any other Cadillac back then, but I have the spacer and PCV valve under my carb, and the port on the valley pan to connect it to, and I don't have a return line port on the top of my fuel filter.  I'm expecting this might be the end of the differences, but not sure.

The duel fuel lines were onball AC equiped cars. But yes that pcv set up was unique.

I'm swapping AC onto my car.  I wonder if I need to upgrade my fuel system

I beleive that vent return is to prevent vapor lock caused by extra heat under the hood due to the compressor

[Clewisiii]

I purchased pre-bent stainless fuel lines from Inline tube. I have been working to figure out the proper routing, and I think I have established the lines are to short.

The back looks good up over the axle.

The two bends on the front look correct where they move away from the body and transfer to the frame.

But they stop short. They should continue up the frame and bend again towards the inside of the spring pocket. Looks like they should be 16 inches longer.

[The Tassie Devil(le)]

Looking at your routing there looks to be too much chance of road obstructions contacting the tubing.   Hopefully, another Member can provide pictures of theirs.

The factory bends shouldn't be simple sweeping bends, but precise angles.

These are images I have collected from others.



Here is the bend going away from the body over to the frame.




Here is the tubes going under a frame body brace.



This is the end of the tubes to the inside of the spring pocket.


I tried stretching as much out of the existing pipes to get them as far forward as possible. But I only got 4 inches.

I found a local guy to rebuild my spare distributor for a good price.

Eventually I will send out my fuel pumps for rebuild, and find a good core for a spare waterpump.

[David Greenburg]

Not sure how helpful I can be since my car doesn't have a/c, but let me know if you want any more fuel line pics. The lines most likely take the same route.

I think I figured it out. I am going to take measurements of all lengths past the last clamp position the inline tube fuel lines end at, then ask Inline if they can make me a set with all their current bends. But leave my measured length past that point. I will do my own bends from there. I dont know if they will do that, or if I will need to completly make my own. But I will need to figure out which tool can make the bubble ends they have.

[The Tassie Devil(le)]

I make my own "bubble" ends by using the Double Flaring tool, but only performing about a 1/4 of the initial squashing and that is it.

All that is needed is the end of the tube to slightly compress, creating a ring to stop the flexible hose from slipping off.

Go too far and the hose will be too hard to push on.

Want pictures?

"I found a local guy to rebuild my spare distributor for a good price."

Yours is a SOLID investment.  I've discovered a couple of often overlooked distributor components that negatively affect engine performance.  These include ruptured diaphragm vacuum advance ,  distributor "stator plate wobble," and mechanical advance springs.

[Clewisiii]

I am going to stop by Inline Tube tomorrow over my lunch break. I will beg them to make a new set of fuel lines with an additional 20 inches on the end of them. They have not been great in the past in making anything with a modification. I cannot tell them what the bend angles need to be. I will just be happy with the additional length. I tried to make a write up showing them the exact issue.

[Clewisiii]

Well I made it to Inline Tube, and it took some back and forth but they are going to make me tubes with 15 extra inches on the end.

At first he asked Pump end, or tank end. I said pump end. Then he said he did not know which ends of the tubes were the pump end.

At first I asked for 20 inches from the last bend. He then showed me a very crude sketch of the two lines, fuel supply had the bend in the sketch, but the vapor return did not. I told him that they were a matched pair and what they sent had a bend. He said maybe I ordered two supply lines. I said no one was 1/4 and one was 5/16.

To eliminate this confusion I said just add 15 straight inches on the very end. Then I marked his papers with what I beleved to be the pump end.

So we will seehow this turns out after they make them.

Getting all the supplies ready for my distributor rebuild.

I really know nothing about points or their adjustment. The last one came back to me ready to go.

I hope the local rebuilder can give me a lesson or teach me about what I should look for.
