68-69 patrol in Tucson

[69patroller]

Hey patrollers so I’m trying to restore my 68 sold as 69 patrol. Currently having trouble even starting it, it turns over but having issues with distributer. Have already been on another post talking about distributer issues and the possibility of swapping to electronic ignition or even a forklift distributer. Main issue right now is sometimes it is trying to start, backfiring some and even running for a second or so. I have questions about the carburetor so putting some pictures up to see if you guys can help. There’s a vacuum line coming from the carburetor that splits to a T-joint with a spring on it and one end goes to engine, the other is just dangling. On the side of carburetor above the throttle but below the choke is another spring loaded arm but not sure how it’s supposed to connect. Need some guidance from the experts if possible. Thanks in advance

First of all I am remiss in saying "Welcome to 60Patrol! "

I would start with the carb, have it rebuilt. The vacuum lines are not a big deal, they don't keep it from running. The loose lines would go to the air filter housing that should sit next to the carb.

Thanks! I’ll get some pictures of the whole vehicle up later today. And ya I’m starting to think it’s something to do with the carb. Took it all apart yesterday and soaked parts in cleaner. Gonna reassemble today with new seals and go from there. Will keep updating on my journey to get this beauty roadworthy and eventually my daily driver

Alright patrollers so got my carb rebuilt. She started right up! Next up is the fuel pump. Wasn’t getting any fuel so I started taking apart. I got all the bolts out but it’s very stuck together. I wanted to post here before I just ripped it off in case there’s something else I should be doing. I got a pic here of what it looks like after I did a rough cleaning of the outside and removal of the bolts. This thing had like a 1/4 inch if grime covering it haha

The diaphragm is sticking the two halves of the pump together. The important thing is to not damage the pump casing and other parts, the diaphragm is going to be junk anyway. Be sure that you save the phenolic spacer that was installed between the engine block and the pump, it is important that this spacer is reinstalled.

Until recently a lot of Patrol owners were using Nissan P40 engine fork lift fuel pumps, but the cost of those had shot up ridiculously high in the last couple of years. Use the search function here on the forum to find out more about that option.

The correct rebuild kits for these Patrol fuel pumps are difficult to find, and if you do find one will it be made of material that withstands the alcohol-laced gasoline? Many Patrol owners have sent their fuel pumps to Then and Now Automotive (https://www.then-now-auto.com/) to be rebuilt. I had them rebuild two pumps, and L60Boerne has had them do several. They use gasohol-resistant materials, and do a great job.

Another option is to remove the stock fuel pump and replace with an electric fuel pump (which I'm not a fan of but I know a lot of folks use them).

I made sure to keep the spacer intact and after just cleaning all the grime off it I put it back on and amazingly it worked so the diaphragm is still holding. I think I need to adjust the float in the carb because it sounds like it’s struggling to keep fuel in it and when I disconnected the fuel line and turned the ignition on, fuel came out from the pump really well.

Unrelated to any issues but figured I’d get at least one picture of my patrol up, and yes I know it’s not a great pic but it’s tightly parked still so I can’t really get a fully body shot haha

Not sure how long yours has sat, nor how old the pump is. But let me tell you what happened to me as far as these pumps. My Patrol had sat many years, and so I got a "core" pump from another forum member; the intent was to send it off to be rebuilt. But, it actually seemed to be a usable pump so I installed it. And the Patrol did run ok with it on. But it also pumped about a gallon of gas into the crankcase! Don't get me wrong, this was totally my fault, and no fault of the other member because the pump was sold as a core to be rebuilt. I mention this only to illustrate that a Patrol pump can be as much as 60+ years old, plus most likely the rubber in them won't hold up to gasohol. You could end up with a crankcase full of gas; luckily I realized what had happened and dumped the oil, and didn't drive anywhere with the gas/oil mix in the engine.

Offered in the hopes that no one else will have this happen to them.

[69patroller]

No way that’s crazy! Good thing you caught it early. I’ll definitely keep that in mind. Gotta do an oil change on it anyway before I move it anywhere so I’ll be checking that out for sure. Thanks!

Alright patrollers so I’m running into some issues with my carburetor. It doesn’t pump fuel at all. The fuel pump is working (I disconnected line from carburetor to test and it pushes fuel no problem). I’ve rebuilt the carb, adjusted the float, adjusted the idle, adjusted distributor to get timing as good as I can with just pouring gas directly into carb. I’m hitting a wall though and not really sure what the issue is. It idles great if I pour gas into carb as well. Short of buying a new carb what suggestions would anyone have?
