RussO Posted August 10, 2014 Report Posted August 10, 2014 Our 1947 Plymouth sedan is stalling when we're driving on uphill slopes. I thought it may have been overheating, so we removed the thermostat and replaced the antifreeze. When that didn't work, I tried checking the fuel filter, and tightened the carb connector screws (rebuilt the carb last year). This is the wife and I's first project together so I'm kind of scratching my head to figure out if it's fuel supply, Fliud drive (10W oil is in it), or something else. Quote
Niel Hoback Posted August 10, 2014 Report Posted August 10, 2014 Check your float level, might be low. Timing about 2-5 degrees ahead? How'd you get fluid drive in a P-15? Quote
RussO Posted August 10, 2014 Author Report Posted August 10, 2014 I had originally set the float a little high to compensate for the ethanol in todays gas. But it fires up no problem, even hot. As for the fluid drive, I thought I saw they were standard in those models, I may have been wrong. But they're covered in the 1948 Master Shop Catalogues. Quote
Niel Hoback Posted August 10, 2014 Report Posted August 10, 2014 Ah! I see you're in Canada. That explains it. Quote
RussO Posted August 10, 2014 Author Report Posted August 10, 2014 It's not a fluid drive, I went back through the owners manual & I should be using 80w for summer. But I had just changed it over to 10w last week after I had found a website talking about the fluid. I'll be switching back to 80w, but the stalling was happening prior to the fluid change. Quote
RussO Posted August 10, 2014 Author Report Posted August 10, 2014 Yes, she was built in Missisauga. Quote
Niel Hoback Posted August 10, 2014 Report Posted August 10, 2014 How well does it restart after it stalls? Quote
Niel Hoback Posted August 10, 2014 Report Posted August 10, 2014 If its not pinging when pulling a hill, move the spark up a few degrees and try it again. Is it a steep hill where you should downshift to second? BTW, put the thermostat back. Quote
RussO Posted August 10, 2014 Author Report Posted August 10, 2014 It had stalled in second before. The thermostat was seized, causing it to overheat and boil over at 160 F. Quote

RussO Posted August 10, 2014 Author Report Posted August 10, 2014 Sorry about the triple post, on my phone. Quote
Niel Hoback Posted August 11, 2014 Report Posted August 11, 2014 You may have a weak fuel pump, but you definitely need a thermostat. Check your fuel flow by the method in the manual. Quote
RussO Posted August 11, 2014 Author Report Posted August 11, 2014 Thanks for the input, I'm going to try that. Quote
greg g Posted August 11, 2014 Report Posted August 11, 2014 Have you checked your fuel pump output? there is a simple test in the manual to see if you are getting proper volume of flow for all driving conditions. Quote
Don Coatney Posted August 11, 2014 Report Posted August 11, 2014 Very hard for a radiator to boil over at 160 degrees. Did you fill your radiator all the way to the top? If you do that the radiator will overflow until it finds the level it is comfortable with. Once it finds that level do not add any more coolant. Quote
ptwothree Posted August 11, 2014 Report Posted August 11, 2014 45 years ago, I had a car that ran great till a hill would come along....then it would quit like running out of gas. Turned out to be a cracked flex hose in the fuel line. Just broken enough to suck air instead of gas on a moderate hill. $1.49 for a new one at Pep Boys was the fix. 1 Quote
RussO Posted August 11, 2014 Author Report Posted August 11, 2014 That sounds like my problem. Last year when we were trying to get it started I took the fuel pump apart to check the diaphragm and clean the mesh. The fuel line that was on there was a old rubber hose that was pretty well eaten through. Of course there's no Pep Boys here, but I was able to find a steel brake line that I bent into shape. We at least know a couple of parts places this year that may have it, without telling us if the car isn't in the database they can't help us. Quote
1950 Special Deluxe Posted August 11, 2014 Report Posted August 11, 2014 I took my old rubber fuel line to a hydraulic shop and they made for me. Quote
Don Coatney Posted August 11, 2014 Report Posted August 11, 2014 I was able to find a steel brake line that I bent into shape. Use caution replacing the rubber flex line with a solid steel line. The steel line from the tank is attached to the frame and does not move. But the engine is mounted in rubber and it does move making it quite possible that the new steel line will develop a crack.

desoto1939 Posted August 11, 2014 Report Posted August 11, 2014 If you can not get a replacemnet hose to fit your car then go to a good auto supply and get the two brass fitting for the fule line end and the other for the in line hole onthe pump then get a fuel line rubber hose and then some allegsator screw clamps and make you own. Screw inthe two fittings into each hole then put the clamps on the rubber hose and attach them to the fittings and screw them tight. Rich HArtung Desoto1939@aol.com Quote
greg g Posted August 11, 2014 Report Posted August 11, 2014 I used a steel piece cut in half, flaired, offset a bit and connected with a loop of fuel line. Quote
