Peder, I am glad the you found the problem with your hard starting. Your description of the problem (reduced fuel level in the sediment bowl on the fuel pump) led me to my suggestion of a leaking bowl gasket. I have a glass bowl pump on my 40 Merc and it is full after sitting all winter. If yours is still losing fuel after sitting for a while, you do have an air leak and your car will prime the carburetor faster if you find and repair the leak. I have posted a test to check fuel delivery several times. You may want to perform the test on your lovely Mercury to ensure that the fuel system is in good operating condition. Many times, we fix one problem and don't find the others that are lurking to cause problems. Here is an article that I wrote for the V-8 Times.

With regards to the fuel pump, and its correctness for the 1946 Mercury. how do I actually determine when my car was built? These cars don't have VIN no's...my chassis no. is 99A-1227666...does this no. indicate the assembly date? I've never really understood this....I have however found stamped on one of the trunk panels...Ford Motor Company, October 1946. Is that a good indication? This car was bought from the family of the first owner, so I am the second owner since 1946. Thanks to everyone for your help! Peder

Peder,if that is an Oct. 46 car it must have been 1 of the last 46's made and could have installed a new for 47 glass bowl pump. The 47's were almost out in Oct. 46.New 47 models I assume came out in Nov. of 46. OMO ken ct.

Peder, the cutoff dates for changes to the 46-48 Mercury's are not known. Some changes occurred in 1946 at some plants and were not implemented until 1947 in other plants. Original cars, like yours and Steve's, are a gold mine of information. The date codes on glass, instruments and other parts are the best indicators of when a car was built. Your serial number is in the middle of the range for all V-8 engines made in the 1946 model year, but you provide a part stamped with a date that is near the end of 1946 production, so we have to believe that the car was manufactured after the first of October, 1946. If there are dates stamped on amy of the instruments, like the clock or speedometer, they would also be an indicator of build date. If the car has any original glass the date codes on it would also help determine the range of the build date. According to the date given by Steve, your Mercury could very well have been delivered with the glass bowl fuel pump.

Are you using that daxn ethanol fuel? It evaporates very fast and the gas is mixed in with it, so tit takes the gas with it, that's a problem. Don't believe it? put a little alchohol in a small container and watch it disappear. It evapoates very quickly, because it's a cousin of acetone and laquer thinner, and you know how fast they evaporate don't you?
Regards, Steve Lee

Tom...I managed to read some codes from the windows that are original...rear window reads Herculite AS 976? Right pass. front J DF? Right wing also J DF? Quarter window rear AS F-S? Left wing H DF, possibly AS-FS? Left window driver J DF? I use question marks because the markings on these windows are 72 years old, and hard to read accurately...hope it's possible to decipher when the car was manufactured? Thanks.... Peder

Peder, go to this E-bay page to see the date format used on USA manufactured Ford cars. https://www.ebay.com/itm/1932-52-Ford-glass-etching-kit-original-style-glass-bugs-for-your-restoration-/352211913786 The date shown is for March 1973 (3 Ford 37) windshield. The markings that you gave for the rear quarter windows probably have the date code. I am not familiar with the other markings that you posted, so they may also carry a date code.

Tom... Now read the markings on both sides of the Ford script...most my windows are original...they read: J, meaning the month of October, and DF, meaning the year 1946 (J is the 10th month, D for 4 and F 6)...seem to be logical and indicate that my car was mfg. in October of 1946? Back to the 2 pumps available that year...what is the difference... technically and mechanically, besides looks? Btw....looks like the gas line coming from the tank has a smaller diameter (replaced back in '05) and not corresponding with the hole in the flex fuel line...thus causing air to be sucked instead of gas...car starts right up after being driven in the course of a day, but if not started up in several days, it will not start without "help"... Thanks.... Peder

Peder, Yes, your car is a late 1946 car. I do not know the date when the glass bowl fuel pump was put into production. The glass bowl pump has a larger sediment bowl than the 41-46 pump and it is easier to clean. Other than that, there is no difference in function. The line coming from the tank should be a 1/4" steel line with a copper coating. The correct line can be purchased from Roy Nacewicz and Narraganset Reproductions. I believe that they both carry the flex line as well. http://fordscript.com/ http://www.narragansettreproductions.com/ I don't understand how the incorrect size steel line or flex line could be connected together. The fittings for smaller lines would not have the correct thread for the flex line.

Tom... The line mounted back in 2005 was of a smaller dimension than a 1/4"...the fitting is correct, but not the line...making for air to be sucked in....have used silicone gasket "glue" to hopefully remedy the situation until I can get the correct dimension fuel line mounted.... It's hard to communicate so far away.....but thanks again for all your help!!! Peder
