1934 International C1

The diaphragm in the fuel pump is dried out and started to leak. No new pumps or kits are available, I have 2 spare pumps but they didn’t have a useable diaphragm. As it turns out the diaphragm in a Holden 179 pump is the same and I have one, both pumps are AC and it’s possible to put the top of a 179 pump on a ‘34 C1 pump if needed. Only problem is the pushrod is different and it’s peened on, so a little surgery and all fixed.

Someone has done a very creative fix on the filter side of that pump. You can see where the fuel originally came in on the left; this has all been cut off and the hole tapped out to take the pipe. I have one of these pumps on a 1934 Bedford where this part has burst from corrosion, I suspect the same has happened here. Very interesting!

Thanks for posting, Jarrod.

Well the C1 is on CPS now, I’ve been out doing the shakedown miles and sorting the issues. It drives like an old car, happy at 35 mph, but the driver has a stupid grin on his face!!

I bet the grin is huge though

Enjoy

Ba ha ha ha!

That grin was a long time coming. Enjoy!

An update on the ute. The engine kept on cutting out and kept me busy finding the cause of it, it was so bad I made up 1 litre fuel tank to hang in the engine bay to get me home. First check was the fuel pick up line in the tank that I made and it got a haircut in case it was too long, next the fuel tank vent inside the filler neck had a low spot that held fuel, so that was cut short and still no joy.

 


Next re route the fuel tank vent hose as it had a low spot and held fuel, not that either.

 

Check the fuel pump and found a lazy spring, not that, the float level was low but not the cause.

All along I had wondered if it was supposed to have a heat shield between the exhaust manifold and the fuel pump so had a look in the parts book, yes it should have, so made up one and bingo, it stopped cutting out on me. Fuel vaporization due to low air flow was the problem. 

 

A good find. Dodge flat 6 engines are renowned for this problem. A sheet of Alfoil over the pump is enough to get you home. Fuel pumps don't like wheelspinning on steam.

Our ‘38 Nash had this problem, it was in my Wife’s family from new. When  a stammer appears switching on an electric fuel pump fitted at the tank sorts it.The exhaust pipe heads forward, down then back closely above car’s pump, I put the pump on to get fuel up to carby if car had been unused, the vaporising cure is a bonus. As long as the diaphragm in the mechanical pump is sound should be OK.
