I posted earlier about a 73 Maverick with 23,000 original miles not getting fuel to a new fuel pump. It has not been ran until 1990 but will run as long as gas is poured into the carb. Would the original carb prevent it? I replaced the rotted rubber line to the fuel pump and blew air back into the tank through the line and heard gas bubbling.
Is fuel getting to the carb? Pull the fuel line off at the carb and crank it and see if fuel comes out. If so then start looking at the carb.
No fuel to the carb. New fuel pump and rubber hose from the fuel pump to the line coming from the tank.
When blowing out the fuel line I think you suppose to have the line disconnected from the tank so trash doesn't get blowed back inside the tank only to clog the fuel line again. The air pressure most likely blew the screen sock off the end of the pickup tube.
I got gas to the carb now and know the carb needs work. I saw other post on this forum they are problematic. Is their a good alternative other than going with the Clifford setup with Weber carbs? The car is all original and I don't want to get to radical but am open to improving it.
Maybe not enough gas in the tank for the pump to pull it. It already had at at least three gallons I added before I changed the fuel pump. I added another two gallons yesterday. I blew low pressure air back from the fuel line at the pump while the cap was still off. Primed the carb and it ran until the gas ran out. I pulled the line at the carb and cranked it over, gas came out. I had previously blew air backward to the tank before and got nothing which made me think the fuel pump was bad. The gas that pump into a cup did not smell or look bad. The carb gets removed today. I have a original Ford factory rebuild kit for the carb my brother got when they was throwing away new old parts at Ford dealer he worked at in 1992.
The only thing used out of the kit was the fuel filter that came separately in the box. Everything else was sealed. I opened it today and seems every thing is ok. The only rubber part is the accelerator pump and it looked good, not hard or brittle. I did get it to run on its on today for about 10 minutes by constantly stomping the gas pedal until my leg cramped. I noticed the pump wasn't moving much, got a new fuel filter and sprayed the inlet. It freed the pump but now its flooding. I got the carb off, Going tear it down tommorrow. Hopefully just the needle valve is stuck from varnish.
Dude, rebuild the entire carb not just the needle if it has been sitting around since 1990, that was nearly 30 years ago!
Even when the car is "out of gas" there is still a gallon or more in the tank below the level of the pick up. If that has been in there since 1990, it is real icky. I dont think adding fresh gas to that is going to fix it. If you dont drain your tank, at least install a generic in line fuel filter Before the fuel pump. If the flow of crud keeps getting into your carb, you will get very good at rebuilding it. Your fuel tank may need some thorough attention.....mine sure did.
Finally got the Maverick to run. Installed a rebuilt carb, New spark plug wires and distributor cap. It statted running better after a while. New spark plugs are next. It has odd problem. It was running bad and started replacing vacuum hoses while it was running I pulled the pvc valve out of the valve cover and it immediately ran better. It seem like it was choking before I pulled it. When I put back in, it started choking down again. I felt vacuum and heard the pvc valve clicked as I cover the end of it so it doesn't seemed to be plugged. Any ideas?
are the air screws set right? use a vacuum gauge. google that if you dont know how. its the best way to set those screws.
