    Can a leaking fuel pump gasket cause vacuum leak?

    Well I've installed a vacuum gauge on it to see where the vacuum is sitting at idle and it's 17-18 which according to the gauge is in the low side of the good zone. I would like it if it were higher. I don't know what the mileage or the age of the rebuild on this engine is if at all it was ever...

    Can a leaking fuel pump gasket cause vacuum leak?

    I don't smell any fuel in the oil so hopefully it hasn't started to get into the pan. I'll have it changed within a week. So it won't be driven all week. I was told it could be an accelerator pump issue but I swapped out the carb two different times with another and the problem always remained...

    Can a leaking fuel pump gasket cause vacuum leak?

    So I've got my 65 Valiant driveable now. Even got it tagged and insured now. Drove it around the neighborhood a few times and it does good. It's the 170 with the Holley 1920 the correct oem number too, less than a year old. I believe I can pretty much drive it wherever and however long I feel ok...

    Can fuel pump be bad with a constant 5-6psi reading?

    I tried warming up the engine to normal temp then plugged vacuum advance and carb fitting. Nothing changed at all in the way it runs. After that I stopped and checked to make sure my choke wasn't stuck but it was fully open. I stopped and looked at the fuel stream when I rotated the throttle. I...

    Can fuel pump be bad with a constant 5-6psi reading?

    I'm going to try unplugging the distributor vacuum advance first. I suspected it could be a problem because I thought it happened on my Charger too. I don't have a good vacuum pump or one that's affordable. I did the valve adjustment according to the Chrysler service manual, I think the specs...

    Can fuel pump be bad with a constant 5-6psi reading?

    I thought about trying the test of disconnecting the vacuum advance and plugging it and then test driving. I don't think I've done it before. Someone earlier had suggested valves too tight, so I checked them the proper Chrysler way but there was none out of specs. I actually have another...

    Can fuel pump be bad with a constant 5-6psi reading?

    I'm about to give up diagnosing this 65 Valiant I got. I'm desparately trying to get it roadworthy. But I know right now it would be unsafe to drive it on the road. It's got either an ignition issue or fuel issue but I can't figure out for sure how to diagnose where the problem lies. The engine...

    65 170 1bbl Holley 1920 popping through carb

    So I for the most part fixed the exhaust manifold and intake manifold leaks on my 65 Valiant 170. It still leaks in the same spot where the two manifold bolt together eventhough I gooped it up with Copper RTV. Maybe it wasn't fully cured yet but it is a lot quieter. It starts super easy even...

    Can anyone help me with a Plymouth choke problem?

    I guess I'll try out the new choke thermostat when I get it. I just hope I can get the original broken screw out of the manifold. Everyone I've seen in the junkyard all had the screws broken in them too. At least it runs. Not bad for sitting for two years. It runs good too if you manually open...

    Can anyone help me with a Plymouth choke problem?

    This isnt the electric choke like on my 73 Charger. This 65 Valiant has a manual choke thermostat. The one on my 73 Charger has an electric heating element. I just won a new OEM replacement manual choke thermostat on EBAY. I just have to get one of the original screws drilled out that broken in...

    Can anyone help me with a Plymouth choke problem?

    I just watched my buddy work on it. He could it running decent when he disconnected the choke heater rod and open in manually. I don't think it was the choke thermostat was moving the choke plate at all.

    Can anyone help me with a Plymouth choke problem?

    On this Plymouth I've got with the 170CID 1bbl Holley 1920 the choke seems to be killing the engine. I got the engine started today after two years of the car sitting. Before that I cleaned/sealed the fuel tank, put new float/sock on the fuel sending unit, rebuilt the 1bbl Holley 1920, new...

    I need pictures of a 65 225 throttle hook up

    Please let me know when you get a photo of the hookup. I've got mine hooked up how I think it should go. It seems pretty obvious the 90 degree angle throttle rod snaps into the bushing on the carb linkage. But my bushing is cracked and I don't know how the rod was retained from coming off.

    What do I do for fuel tank pad on a 65 A-body?

    Hey I removed the fuel tank from my 65 Valiant. I believe that's why it wasn't starting. I rebuilt the carb, put a new fuel filter, air filter, and added a little gas. It started up and quickly died because the fuel was leaking from the center of the fuel tank. So I took it out in about 20...

    I need pictures of a 65 225 throttle hook up

    I'm going to reinstall the carb I rebuilt on my 65 Valiant 225 this weekend. It was kinda rigged up from the previous owner. I want to hook it all up the factory way. Does anyone have a clear picture of how it should be hooked up?

    I need some help finding a Holley 1920 part

    I was rebuilding the 1bbl Holley 1920 on my 65 Valiant because that was all it needed to get it started. The inlet needle was bad and all the gaskets were leaking and it was improperly hooked up without a choke. I bought a kit and rebuilt it. I also labeled and bagged everything as I went. So...

    Fuel tank/system replacement on a 65 4-DR Valiant

    I went to the house where I have the car stored at yesterday and played with a little. It appears the tank may have a small leak in it. But there is still some gas in it. I sprayed a little starting fluid in the cabr and tried to start it. It fired up but only ran what was in the carb and then...

    Fuel tank/system replacement on a 65 4-DR Valiant

    How difficult is it to replace the fuel tank on a 65 Valiant 4-DR? Upon having the car towed to my house today I think either a fuel line broke or a hole in the fuel tank occured, there was gas everywhere. Where's the most economical place to find one of these fuel tanks new? Should I get a fuel...
