Mysta2 Posted July 17, 2019 Author Report Share Posted July 17, 2019 In the carb on my '62 Ranchero the accelerator pump squirt was above the plainly visible with the filter off. In this carb, I cannot see it. should I be able to? Can you see the last video that I posted? I'm assuming that it would squirt out of the bottom of those two rings in there. I know that pulling the choke lever closes the choke. But you made it sound as if the "choke flap" would close after the first accelerator pump. Or did you simply mean that I needed to close the choke (manually) after pumping to increase the chance of a successful start? Quote Link to comment
banzai510(hainz) Posted July 17, 2019 Report Share Posted July 17, 2019 yes its OBVIOUS that you should see it squirt when you cycle the linkage. closeing the choke inriches the fuel mixture to help start it Quote Link to comment

Yes, you should see the fuel squirt down the barrel. I was waiting for this. If it has been sitting for a while, the accelerator pump diaphragm could be brittle and torn, or the circuit could be clogged. Start by removing the pump diaphragm to inspect it.

banzai510(hainz) Posted July 18, 2019 Report Share Posted July 18, 2019 (edited) I don't get the fuel pump switch thing???? WHY????? I like the key turing on fuel pump on as it should be. READ THIS!!!!!!!!!!!!!!!!!!! oh I don't see gas being squirted in.Either the pump isn't pumping fuel to the carb or the needle valve in carb isn't letting gas in the bowl. or the accel pump diaprame is bad. A diaphrame bad most lilkely will leak on the side of of the square looking fiting which pushes it in. It will have 4 screws. also. you hit the carb so fast the main barrel should be on the valve cover side. that where the squirt will come from.. Unless this is a different carb carb where the main barrel is on the driver side. Usually for the French cars that I have seen. Not that it matters PS that fuel pumps sound like shit. They shouldn't be that loud I would think since I saw a photo the choke flap is closed cause you have pulled the wire to close it. as motor warms up you push the choke back in to open the flap Edited July 18, 2019 by banzai510(hainz) Quote Link to comment

If you are in an accident involving an engine fire or a ruptured fuel line, you may not be able to turn the ignition off.... and the pump just keeps pumping till the tank is empty.

Thanks for the info. also. you hit the carb so fast the main barrel should be on the valve cover side. that where the squirt will come from.. Unless this is a different carb carb where the main barrel is on the driver side. Usually for the French cars that I have seen. Not that it matters I'll look into this and see if I can see which is opening first, this is the engine setup that I bought the truck with. I don't know much about it. PS that fuel pumps sound like shit. They shouldn't be that loud I would think I have no idea what it's supposed to sound like, the flow seems constant and dependable, but I don't have anything to compare it to. I did remove the cap from it and make sure that it all looked clean and intact at one point. It sounds like most people are unfamiliar with the stock electric fuel pump on this truck. Have you heard examples of this pump that sounded different? Or are you just guessing? Thanks for the advice. Quote Link to comment
banzai510(hainz) Posted July 23, 2019 Report Share Posted July 23, 2019 They seem a lot more quiet. Datzenmike weould be more of a expert on those Quote Link to comment
datzenmike Posted July 23, 2019 Report Share Posted July 23, 2019 I put one on my 620 and in the cab you could just hear it. Prrrrrrrrrrrr. Quote Link to comment
Mysta2 Posted July 26, 2019 Author Report Share Posted July 26, 2019 (edited) Anyone have a source for a replacement pump? I'd be happy to swap in a new one, but I don't want an aftermarket one. What I think is the accel pump on the side is not connected to the linkage at all. I still couldn't get it to squirt anything pumping it by hand though. The passenger side barrel does seem to be the primary. Edited July 26, 2019 by Mysta2 Quote Link to comment
banzai510(hainz) Posted July 26, 2019 Report Share Posted July 26, 2019 the accel pump arm is stuck in the IN mode. go to the side where the squared diaphrame is. now when you cycle the linkage the arm should move. if the arm don't move its stuck. See if you can get some needle nose pliers and wd 40 or something to lube that arm. I don't know if somebody else had this and put the diaphrame in backwards.if that's possible Quote Link to comment
