Wrong Fuel Pump For 134?

I have a '57 CJ6 with the 134. It had an electric pump on it which didn't work. I bought a mechanical 2195 (for electric wipers) and the arm isn't hitting the cam lobe. Even with the spacer removed. I turned the engine over and can feel the lobe rising & falling. It doesn't feel worn down. Just setting it in without bolts, it drops down on the lobe and moves. Rockauto and Oreilly calls for this pump. Any ideas? Or should I just order a new 6v pump?

 

Looks right. It's what's in my fhead

 

Ok, thanks. Just wanted to make sure. I'll order a 6v electric and throw this in the extra parts box for the new owner to deal with. In the meantime I'll hook up a 12v pump w/battery to get it running.

 

I bought one that looks like that from Rockauto, and it wouldn't work either. I'll look for that one tomorrow to see if it has the same numbers as yours on it.

I have reverted to rebuilding the old AC style pumps.

 

It works if you actuate by hand. Just doesn't contact lobe. I would appreciate you checking Oldpappy. I'm hoping some drunk guy at the factory screwed this up with the wrong arm, or there is a different pump needed. But then, there might be a reason this had an electric. Wish I knew what was happening with this Jeep when it was parked 25 years ago. I hooked up a good electric. Got fuel, but still getting intermittent firing. Already installed new ignition switch and points. 90 psi on all cylinders. Had compression on #1, rotor pointing at 1. Nice spark at coil wire. Couple times it ran great for 5 seconds. Now to see where and when it's losing spark.

 

Good luck.

I will look for that pump tomorrow. I think I know the general area of my rat warren storage system it may be in.

 

Welcome from Michigan. It may need a spacer between the block and the fuel pump, I ran into that on a Morgan I was helping my buddy with. Just saying.

 

The one I have has the same top number, but a different number on bottom, but it looks just like yours. After finding it again I found my notes. This is not the one I bought that didn't work. I don't think I ever actually tried this one. The one I bought that didn't work was one of the imports with the divided glass bowl on top. That one worked for a little while, but the seals and diaphragm deteriorated.

 

Yes Sir......From what I have gathered, there is a spacer needed for some of those pumps. Just wondering what spacer you removed ?
The Ethanol is causing the Chinese made units to have failed diaphragms.

 

Lockman is right without the spacer the fuel pump is to far in and will not make the needed fuel pressure.

 

The reason is I got a M38A1 that had a new fuel pump on it and a electric fuel pump. It was running off the electric pump. The manual pump was missing the spacer making it go in to far to make fuel pressure. I installed a spacer and good fuel pressure.

 

The pump comes with 2 gaskets, so I assumed the spacer that was still on the block with the block off plate is needed. The spacer is about 1/8" thick. You got me second guessing my skills, so I went out and tried again. With the pump installed with spacer, bolts just barely loose enough to feel movement, you can feel just the slightest bit of movement. Nowhere near enough to stroke the diaphragm. Pardon the crap camera pics.

It's like this thing wants to be flipped. Just can't because of the mounting flange and it would hit the motor mount plate. Guess I could take it apart and clock it. Ignore the fittings, stole them of the electric.

 

The spacer that I used is about 1/2 thick. Midwest Military has the spacer in stock for around 20.00.

 

Ok. I found the spacer at Midwest. Thank you. So, I'm also missing an adapter plate to flip this where the arm comes in under the cam lobe?

 

The spacer is used to reduce fuel pressure. The thicker the spacer, the shorter the stroke and hence the lowered fuel pressure. A single-action pump, like yours, does not require a spacer.

 

Ok, thanks guys. I found a pic showing the pump with the diaphragm portion on top, which matches the block flange. I don't know what is wrong with this engine, but the lobe isn't contacting the arm. Back in the box it goes. The 6v pump should arrive in couple days. If you want to continue with this problem on your own, the ad will be up this weekend.

 

I rotate the top and put the inlet in the back.

 

Cool. Thanks, Rick. I thought that would be possible.
I hope I didn't sound irritated about the pump. Didn't mean to. I was just hoping to get that sorted before selling. The next guy can figure out what is wrong. It will just come with a 6v pump installed.
