Technical Discussion / 41 PT 125 Fuel Line Routing
Last post by PT Moe - February 18, 2024, 02:17:00 PM
1941 Ply PT125. Not sure if we have a current Plymouth Commercial tech advisor so posting here.
Got my rebuilt flathead back in the frame and am now trying to figure out my gas line routing. Looking at pictures I took back in the late '70's when I took the truck apart I think I got it somewhat figured out but would appreciate any verification. Looks like it comes out of the tank and goes through a riveted clip under the frame just behind the battery, Up along the outside of the frame through another riveted clip and up over the front shock mount to the front of the frame crossmember that supports the motor mount and turns back on the passenger side to a flex line at the fuel pump. Does not look like much room at the bottom of frame crossmember with the harmonic balancer and the radiator support that bolts there. Also, the line was spliced part way with copper so it may not have been routed as original. Running 5/16 NiCopp line. Thanks for any help.  Jeff

Maybe your old one had 6 and now has 2.  Anyway, i would not worry about it.  If it fits use it.

I bought a pump in Australia which looks to be the same as follows

None of the online photos show the impeller. The original is 2 vanes and the one I bought has a different impeller with six vanes.

I am aware of the other changes to the backing plate that are required from online forums but no-one has discussed the impeller and if the extra vanes creates any problems?

Thanks for your help in advance.

I am restoring my 37 Plymouth coupe and am struggling with how the mechanical throttle and starter linkage mounts to the firewall.
Does anyone have a photo?

A lean mixture can cause the car to run hot and as the mixture takes longer to burn some of it will be burning in the exhaust manifold heating it up.

Another thing that can get the exhaust manifold hot is burnt exhaust valves.

So do a compression check and verify your carburetor mixture is correct. And, for that matter, that you ignition timing is correct.

Warm the car up to an idle speed.  Turn idle screw slowly clockwise until engine starts to falter, the turn same screw counterclockwise in engine starts to roll/surge from being too rich.  Turn screw clockwise again until you get the smoothest operation.

What should the mixture screw at the base of the carb be-out from seated 1 turn or more? less?
the car misses when the choke is wide open. seemingly runs ok when the choke is half closed-
Thank you ahead of time for your thoughts-

Hello Plymouth Family- I ran the car just now- and possibly the cover was stuck??
it now rotates by itself 90 degrees-however the exhaust manifold glows red...not sure that
in and of itself is correct? but the heat riser mechanism cover moves-when the car is running-Thank you!!
