  1. My '41 Fleetwood has the thermostat linkage disconnected and the radiator louvers are stuck. I actually doubt that it even has a thermostat installed. It's no problem in summer, but this time if year, the engine doesn't get above 140 degrees. Could I install in-line thermostats in the coolant hoses like in the old Ford v-8s? Thanks
  2. There are the rubber hoses used to connect the fuel pump and also some under the hood. The ones under the hood are fairly old and I'm going to replace them. Thanks.
  3. Done, and I think that was part of the problem. Thanks.
  4. Just tried your suggestion and the car ran! Not for long, but a significant improvement. Ran for about 3 or 4 minutes with the pressure fluctuating between 2 and 4 psi. I located the fill pipe vent and it was plugged shut with a long bolt with tape over the end to keep the bolt from falling out! Looks to have been done a long time ago. I removed the bolt and also cleaned out the gas cap vent. Put the cap back on and the car started and ran, but again not for long. Runs fairly good at high RMP, but will not idle. Anyway, looks like you got me headed in the right direction. Thanks v
  5. Before reconnecting the fuel line to the carb, I ran the pump and got a good steady flow of fuel. How could the pump be defective if it produces 5 psi of pressure before starting the engine?
  6. Pump is mounted on the rear frame about 3 feet forward of the tank and lower than the tank.
  7. I don't use the fuel gauge. I added fuel to the tank as soon s the problem came up. I blew back the line with a compressor and also used a vacuum pull to pull fuel forward. Both showed no obstruction.
  8. My '46 Merc died on me. mechanical fuel pump had a grass bowl and I could see there was no fuel. Checked the fuel line and there was no obstruction. Gas tank is about 1/2 full. I replaced the pump with a 6v Airtech pump wired directly to the ignition. When I turn on the ignition without the engine running, I get about 5 PSI of pressure. As soon as I start the engine, the pressure slowly drops to zero. The engine continues to run for about a minute, then dies. Checked the carb. It's clean and float seems to be ok. Would sure appreciate some help.😔
  9. Hi. Just got a nice Arrow 285 turn signal kit. Problem is there is no wiring diagram. I've looked at dozens on the Web, but none seem to match. I have seven wires coming out of the switch. The red and black go to the flasher. That leaves yellow, blue, white, green, and brown. I know one goes to the brake light switch and the other 4 go to the individual signal lights. But, which is which? Thanks
  10. I'm looking for information related to the 1937 Plymouth PT50 pickup truck. Owner's manual, shop manual, parts manual. Thanks
  11. Just loose, but I'd like to use it on a car.
  12. I have a vintage oil filter canister with no markings on it. How can I find out what size replaceable filter insert it takes? Thanks
  13. Thanks 19tom40, you hit the nail on the head. No need to post a photo. One look at the cables was all I needed. One cable was 1 gauge and the other was a 4 gauge!.. It's a wonder the thing even cranked. I replaced both cables wot 2/0 high temp cables. Noe the thing cranks like an 8 volt when cold, and no heat problem after running for a while. Thanks again
  14. I have a 1946 Merc coupe flat head V-8. Starts fairly easily. I keep it on a trickle charger. After driving for a few miles and the engine gets up to temp, if I stop and turn it off, it won't restart. It acts as if the battery is dead. Starter will give a couple of grunts, but that's it. A few hours later, after it cools off, it turns over easily and fires right up. What could be causing this? Thanks.
  15. Thanks very much for the info. I was also wondering about the wire gauge, so that's helpful. Was going to use #10 but will now go with #8. Thanks again.
