flint52 Posted July 25, 2015 Report Posted July 25, 2015 Hello, i have a 50 dodge meadowbrook. I replaced the fuel tank last weekend (prior one was leaking) and now i am trying to start my car and it wont. Poured gas down the carb and it would run until that was gone. Tried a couple times hoping the gas would reach the pump. Ended up pulling the filter and its bone dry. Took out the Fuel pump from my car and it looks nothing like the stock pictures online. Its a Carter 684 with 2 ins and 2 outs. Now 2 years ago it did run and drive. so at one point in time it did work. Is there a rebuild/new similar pump that will work or do i need to purchase something else. Thanks Ryan Quote
Plymouthy Adams Posted July 25, 2015 Report Posted July 25, 2015 you forgot to mention if you did or did not check to see if you are really getting fuel out of the tank to the very places you are now checking...when you replaced the tank...did you clean the fuel line forward? or at least back flush the one before connecting to the new tank?

Dave72dt Posted July 25, 2015 Report Posted July 25, 2015 2 years ago it probably had ethanol gas in it that may have eaten up the diaphragm in the pump. \have you checked the fuel line to the tank to see if it's clear? 2 years of sitting can create enough sludge and crud to block the line. Quote
flint52 Posted July 25, 2015 Author Report Posted July 25, 2015 Thanks for the replies yes i am getting fuel through the lines (i did back flush the line) so that's not the issue i think. its just not going any further than that. Quote
Plymouthy Adams Posted July 25, 2015 Report Posted July 25, 2015 with the fuel you poured in the carb and the car running..does the pump inlet have a suction to it? Quote
flint52 Posted July 25, 2015 Author Report Posted July 25, 2015 didnt think to do that (only one person) so bolt the pump back on and have someone start the car while im under and see if there is suction on the inlet? Quote
Plymouthy Adams Posted July 25, 2015 Report Posted July 25, 2015 well..with the pump off and on the bench..this is even much easier and a one man show... Quote
flint52 Posted July 26, 2015 Author Report Posted July 26, 2015 how much force is needed to move the pump lever? it requires quite a bit of force to even budge it. Quote
Jerry Roberts Posted July 26, 2015 Report Posted July 26, 2015 You might have to put a lever on the lever ... like a pipe . Quote
frankturner Posted July 27, 2015 Report Posted July 27, 2015 I'm potentially having the same issue in my car. I was able to disconnect the inlet line to the fuel pump as it was running and put my finger on it, did notice little suction. Quote
flint52 Posted July 27, 2015 Author Report Posted July 27, 2015 so i used a pipe and the lever was able to do gown 1/2" and get suction on the inlet. so is it an issue with my line? what else can it be? Quote
greg g Posted July 27, 2015 Report Posted July 27, 2015 Picture of the pump would be helpful. Some had a vacuum booster for windshield wipers. Some have a brass screen between the inlet and outlet chamber as a filter also these can get fouled especially with rust flakes. Some have a hollow bolt that fastens the lower chamber to the body and flow fuel between the chambers. These can get fouled. The pick up has a filter also, did you shoot some compressed air back through the lines from the inlet? When you get it to flow, do the test for proper flow quantity. test Needs an assistant. Disconnect the fuel line at the inlet of the carb. direct the line into a suitable container. pull the coil wire, and have a helper crank the starter. Count the fuel pulses flowing into the container. 12 pulses should give you 8 to 10 ounces of gas in the container. Less means you still have insufficient flow for proper running down the road. Quote
