1948DodgeD25S Posted January 27 Report Share Posted January 27 My dad passed away recently and now I own his Canadian business coupe me and his car club tried to start it for the funeral but the problem is it is wanting to start but there's no fuel pressure.

Ivan_B Posted January 27 Report Share Posted January 27 Our condolences for your loss. Does the car still have an original engine in it? Would it run of you gravity feed the carburetor? When was the last time the car was on the road? Some pictures are always welcome ? Quote Link to comment Share on other sites More sharing options...
plymouthcranbrook Posted January 27 Report Share Posted January 27 First check to see if the line back to the tank is not plugged. If you have compressed air use a blow gun and try blowing through the line back to the tank from the fuel pump. If that is clear re connect the fuel line to the pump and then disconnect the line at the carburetor. (Note, disconnect the coil from the distributor) Try cranking the motor with the disconnected line going into a coffee can or some type of metal container. Fuel should come out in a steady pulse and pool in the can. If nothing comes out or it is very slow the diaphragm in the pump might have a tear in it or a hole. Older style rubber can be eaten up by alcohol in the gas. You can also see if while cranking it if you feel any pressure coming from the line while cranking the engine.

Sniper Posted January 28 Report Share Posted January 28 Silly question, is there gas in the tank? The gauge might be lying to you. Quote Link to comment Share on other sites More sharing options...

keithb7 Posted January 28 Report Share Posted January 28 Hi @1948DodgeD25S There’s tons of experienced folks here happy to help you. We’ all want to get your car going asap. I’ll refrain from any further tips on the fuel pump pressure until you work through the ideas already presented. Please do report back with any progress or new findings. Keep in mind these fuel pumps can take a long time to prime if the car has been sitting for some time. You’ll be cranking the engine over much longer than you might expect, before fuel is delivered to the carb. Quote Link to comment Share on other sites More sharing options...

That's probably a good idea, given the very little information provided by the TS. I'll just ask one more question: How do you know that there is no/low fuel pressure? ?

1948DodgeD25S Posted January 28 Author Report Share Posted January 28 When we were trying to start it one of the members looked at the gauge showing no pessure.

Ivan_B Posted January 28 Report Share Posted January 28 (edited) That's what I thought. Do you have a fuel pressure gauge installed, or did one of the members put one inline with the carburetor? If the car has not been driven for more than a few years, I would probably avoid trying to run it with the stuff you have in the gas tank, for now We have an original engine with a carburetor, right? It does not really need much pressure to start/run, as long as the carburetor fuel bowl has fuel in it, the car should start. It will eat the bowl and stall, in a minute or two, but it should start alright. Edited January 28 by Ivan_B Quote Link to comment Share on other sites More sharing options...

9 foot box Posted January 31 Report Share Posted January 31 I wouldn’t try starting the car with that old gasoline. It won’t run right, even if it does start. I believe it can hurt the engine, and even cause a valve or more to stick, locking up the engine. A 1/2” drive impact wrench will loosen the tank plug the best way. I would use some Seafoam additive with the fresh gas. Your Dad might have put an electric fuel pump in the car, that’s why you have no fuel pressure. Look for a switch that activates it, if that’s the case. Then you can just pump the old gas out. From the pictures that you posted, it looks like two carburetor’s.

Could be also old cracked fuel hoses, or tank vent seeping a bit. Get a new garage door seal (I did ?). Quote Link to comment Share on other sites More sharing options...

This is a sad thing about modern fuels. .... They really do deteriorate over time. ..... Just not the same gas your father used. I'm not sure on the correct way to eliminate or fix the issue. I did rebuild a carburetor once, it was simply disgusting as it was full of grey goo. It really was just modern gas that has sat for a few years. Gas 7 years ago was not like this .... modern gas is. IMHO, getting rid of gas 2 or 3 years old is a must ..... If you run it through your carburetor you are just asking for a tear down and clean ..... Might need it anyways and a good thing. Back in the 1970's Grandpa filled every junk car fuel tank on his property to be sure to have fuel when he wanted .... It would last over time. Todays modern fuel sucks and 1 year it is pushing if it is still good. I would suggest running it out and getting fresh. When you get modern gas 5 years old, you need to clean the fuel out of the system .... fresh gas and seafoam to clean the fuel system. If you actually ran the vehicle, you may now need to open up the carburetor and clean it. Years ago we could get away with this .... today not so much .... If it runs you can try adding fresh fuel and a cleaner like seafoam to see if it cleans itself out. Quote Link to comment Share on other sites More sharing options...
1948DodgeD25S Posted February 1 Author Report Share Posted February 1 And there is also an oil leak coming from the driver side doesn't look like it's from the oil pan or the head Quote Link to comment Share on other sites More sharing options...
Dave72dt Posted February 1 Report Share Posted February 1 (edited) Oil leak is probably from the road draft tube if you've been running it much at all. If it has a filter, it could also come from that as well as any of the oil lines. Edited February 1 by Dave72dt Quote Link to comment Share on other sites More sharing options...
Ivan_B Posted February 1 Report Share Posted February 1 Or the steering box. Quote Link to comment Share on other sites More sharing options...
1948DodgeD25S Posted February 2 Author Report Share Posted February 2 With the oil leak i think the engine was overfilled so probably the oil pressure relief valve leaked out that over pressure and that valve was also loose Quote Link to comment Share on other sites More sharing options...
