OK I will stop being hard headed and consider almost anything at this point! Perhaps I do have a carb issue that was not manifesting with the old pump. So I installed the NOS pump and it was totally dead - no pressure whatsoever so it was probably and old defect put back in the box. Coincidentally I was looking in the trunk of my other 57 and found that I had a spare NOS aftermarket brand in the original style, so I tried putting that one on. Lots of pressure and also fuel gushing out of carburetor again! Since I am moving and have little time left to pack, I was out of time or would risk not being out of the house in time. Since I won't be able to work on the car in my temporary living location I decided to have it towed over to a shop I've had do work in the past. This gets the car out of my way, and they can rebuild carburetor if needed. I left them a detailed history of the situation so I am anxious to see what they say. I am guessing carburetor rebuild will be standard as that is the one thing that was not yet done as part of my mega tune up!

I agree, if it is loose. The new diaphragm material (that I have seen) is much more flexible than the original though; a very different elasticity. This could allow more stretching per stroke while not being loose. That's my theory at this point. Gonna put the NOS pump in my car tomorrow and see how it goes!

Can somebody post a picture of where the shaft seal goes? I could not find one when I had my trans out.

Absolutely stunning! A work of art! Are there Pace Car decals?

It seems strange, I agree. But I'll see how it runs on the NOS pump and report back. I've had the same situation twice though on two different cars.Also, after thinking about it and seeing the previous posts the diaphragm being the issue makes sense. If it stretches more than the OEM material (which I believe it does after handling both) it seems likely that it could then displace more volume on each stroke, thereby increasing pressure. I am returning the pump that just caused this issue, but still have the other one if I want to experiment in the future, perhaps with my other car. I would have bought the pressure gauge and done it now if not for the fact that I am moving in two weeks and literally every hour counts as I start packing up the garage!

Dan, I tried this tbe first time I had this problem on my 58, and the pressure was so great that after a couple hundred miles the pent up pressure blew the seal out from the top of the pump, sending gas pouring everywhere!

The carburetor was not touched (R&R ONLY) and the car ran fine on it just 2 months ago. Replaced the fuel line because it was brittle; that's it. I just can't think of anything else besides the diaphragm. There aren't too many variables. I wish there was an adjustment built into the pump!

I agree that would be nice but I don't have a gauge. Plus I don't want to spend the extra time and money unless there was some solution that could come from it. If there was a way to adjust the pump then I would certainly do that! One thing is for certain though; it's too high on the rebuild.

Sooooo I finally got the car back together and it fired right up and sounded great, with 2 small issues. First, there was a coolant leak that I couldn't figure out right away. This turned out to be that temp sensor not tight enough so I think I have that solved. However, I have not been able to run it long enough to confirm. The freshly rebuilt fuel pump I put in caused fuel to gush out of the carburetor! The pressure is through the roof. I already took it off and am awaiting an NOS pump that is on order. See the thread I started on this in the post war section fir more detail. Anyway hopefully Saturday will be the day I can go and take the car for a cruise, and take it to its temporary storage spot! I just hope no more issues arise...

I have now had this problem twice and wondering if anyone else has and/or what can be done about it? Twice now (once on a 58 and now a 57 - same pump number) I have installed a newly rebuilt pump with the new type of diaphragm that is supposedly impervious to newer fuel, only to have it cause fuel to gush out of every orifice. Both cars ran well on with old pump (being replaced for good measure and to have original style). Neither had any issue with carburetor, just too much fuel pressure. On the 58 I put a regulator on but after a short while the pent up pressure in the pump caused the seal to blow out the top. Plus the regulator looked terrible. I put an NOS AC pump on and the car ran perfectly. Now, I have the same problem; I bought a newly rebuilt pump thinking the other one was some fluke or I had somehow messed something up (although don't know how that would be possible). I already ordered an NOS pump but this does not seem like a good long term solution. Eventually I will need another one and there are more of these cars on the road than there are NOS pumps. Any solution to this? What is it about these new diaphragms that cause excessive pressure? Is there a way to mitigate this?

I think he means the starter switch that is near the choke

True...if you place no value on whether it is a special or Roadmaster. However even with the body rust the Roadmaster is in far better condition from what I see.

Yes perhaps, but it is a Roadmaster and it is still a much better car to start with than this Special.

My 76C VIN is 7D4026981, which means it was built in Kansas City as car 26,981 and had about 23,174 built after it according to the Standard Catalog of Buick. With the sequence beginning at number 1001, this car was probably right in the middle of the run; January perhaps.

Show this to your wife and she better appreciate yours! Lots of rust patching but a complete and very restorable car. First I have ever seen on Ebay unrestored.

Brandon, you ordered a speedometer from where? Rebuilt, or what?

Well, I did obtain some injuries such as a nasty bruise and lump on my shin as the door swung shut on it while reaching in to fish the new speedo cable through! I also received a few pokes to the scalp over the last few weeks. My knuckles have been good though as I started wearing gloves almost constantly a few years back. The worst though was a bad infection I got while power washing the engine, when I stupidly got my hand in the way and blasted a hole in it. Won't do that again, guaranteed! Oh, what we put up with for the love of these relics of art on wheels.

Getting there! Should be able to get it back on the road next weekend! I was so busy I didn't take any in-betweeners!

I sent you a PM. If you don't get it email me at lancemb48 at Hotmail dot com. Perhaps we can trade speedo and door trim. Thanks

That inspection and the accompanying set of rules is the utmost ridiculous waste of time and money. What an example of misguided socialist bureaucracy! Best of luck getting your Buick on the road.

Looking for good functioning complete assembly or drum. Properly working unit should rest at 0 and stay there until keyway is spun, thereby steadily raising level without bouncing.

Hello, I'm Mr. Ed...

Thanks guys! Here is the hood with new insulation!

Transmission cleaned up and regasketed! It's also in the car. Engine dropping in next weekend!
