‘34 Spark confusion

WELL I wanted to let it run off the temp tank for a second or 2 before I called it quits and forgot the pump was still connected. I think the fuel pump works cause it shot fuel all over the engine. Think I’m definitely done for the day now I don’t need any fires starting. Mistake but happy mistake too
 
Re: ‘34 Spark confusion

Along with with a new flex line I need a new pump to carb line. The one I bought online for the car is about 3 inches to short to fit correctly and caused some leaking. I’m guessing this is because it has a Holley and not a stromberg causing the shortage. What is the best 1/4inch copper tubing I can use to make this?

I’m seeing 1/4 copper line I have the fittings I just need to know where to get some line like this I’m not having the best luck looking around.
 
Re: ‘34 Spark confusion

Those lines are not copper. They are copper clad steel. Copper is not recommended.

I'd use the new copper-nickel alloy they use for brake lines (Cuprinol). The stuff is easy to work, looks good, anti-corrosive, and tough. I re-did the brake lines on my F150 and it was great.

Adding in to this post, took me a few days but I got a new line but lost a nut and ferrule in the process so had to get another set of those. Today I finally got all that hooked up along with a new fuel filter and gasket on that. Now I know the fuel pump as it sprayed fuel all over the day as you guys seen. Today the car started and ran off my bowl in my carb and died. Weird but I noticed “bubbles” in the sediment bowl. I am ordering and waiting on a new flex line as that may be part of the issue. Also ensure I had the screw on the sediment bowl tight so my rubber seal was good. Included another video for any tips.

While it was running it was more bubbles

Re: ‘34 Spark confusion

if i noticed bubbles in the glass sediment bowl of my flathead's fuel pump, i would immediately suspect that air was entering the fuel line somewhere between the sediment bowl and the tank.

to test my suspicions, i would gravity(!) feed fuel into the line starting from the nearest point to the pump as possible. if my suspicions were correct it should fix the problem and a subsequent search should find a leak or two somewhere between the fuel pump and the tank.

Good idea, I’m also seeing some argument on other posts about rubber gasket seals and cork which is better?

i've learned my lessons over the years, and so would buy both. considering the cost of shipping, i might be tempted to buy two(!) of each. try one (your choice) and if it works, throw the other(s) in a drawer...

i had to buy two new fuel pumps (consecutively!) to get one that worked on my recent '41 super deluxe purchase. :(

I've always had better luck with cork sediment bowl gaskets, even though the neoprene ones should be better according to all of my senses. One thing I do is to sand the glass bowl on wet or dry paper on my "Surface Plate" (A 2" thick chunk of granite that is ground perfectly flat) to make sure there are no imperfections in the mounting surface. This solved a vexing long term fuel problem for me about 15 years ago.

I’ll give cork a try! As well as a new flex line. I was thinking it over and when it started the other day edits the new seal the bowl filled up and shot gas everywhere it was pumping good. But with the new seal is when it started bubbling like it is. I’m leaning towards the seal I think. I found a few cork gaskets at tractor supply and orielly. What’s the right dimensions for the gasket?
 
Re: ‘34 Spark confusion

As others have suggested, give your distributor to someone with a machine that knows how to use it. If you are using the early distributor, you might see if you can upgrade to a 37 to 41 unit as new points and condensers are still available from NAPA and you would also need to use the inner and outer caps for a 37 to 41 distributor. For the early distributor if you can find or have made a new (not NOS) condenser and Haney rebuilt coil there should be plenty of the early style new points around. If you cannot find any new point sets for the 32 to 36 distributors I have many sets and would give you a couple. If needed, PM me.

[QUOTE=34 fordor. What’s the right dimensions for the gasket?

2 1/8" outside diameter. The inside diameter can be anywhere between 1 1/2" and 3/4". I've had good luck making one from "Viton".
