replaced fuel pump still cuts out on corners
 
i replaced the fuel pump in my 00' focus dohc a week ago, it used to bog out and hesitate if you were taking a ramp, still does it with a new pump. is there an issue with the canister or somthing? does the canister trap gas so it doesnt starv when cornering? is there a one way valve or somthing that lets it fill?

They redesigned the whole assembly due to a design flaw or something like that. Did you replace just the fuel pump itself or did you upgrade to the newer style?

Are you referring to the charcoal canister? That scavenges fumes from the gas tank and converts them back to liquid gasoline, then that gets sucked up into the engine through the purge valve. A clogged charcoal canister will cause a "whoosh" when you open the fuel cap.

Did you replace the external fuel filter when you replaced the pump? A fuel filter should be purchased at the same time as the pump even if it's been recently replaced in order to honor any warranty.

no i just replaced the pump it self, i had to clean and reuse the canister and socks etc.. what year did they redesign them? like if i went to the junkyard so i know what year to ask for. no ididnt replace the filter but i kind of think thats not going to help, will do it anyways though cause its cheap.

trying not to spend hundreds on a whole new pump assembly for my beater car

Half-ass fixes result in half-ass results; as you now know.


Why didn't you replace the sock filter? (tell the parts store you need one for a 2000'ish Jaguar S-Type, parts system error) It's a $10 filter that is the first line of defense.


Just man up and buy the correct pump new from Ford. It'll save you lots of headaches and redoing work.
Unless you like replacing pumps.

www.rockauto.com check their pump prices out. You probably could've gotten the assembly for less than a pump from the parts store.

I got the pump new for $40 on eBay.. used eBay pumps before in other cars without issue. And I cut an access hole so I don't have to drop the tank so its not a big deal. Ya I will half ass some things on my beater car I'm not gona drop 200 or whatever on the pump . Does anyone know the design flaw? Things pretty simple I don't ee what could go wrong and if its something simple maybe it can be "half ass" repaired.

The diaphragm in the base leaks.
The pressure tube on the top hat aerates the fuel too much.

Oh ok thanks. What year did they fix this or how can I identify the updated part?

craps 10-07-2012 12:14 AM

is there a way to tell the updated ones part at the junkyard? seriously not putting $200+ into this car it has 230k on it

also when i took apart the pump last night, the hard output line that snaps in the top has 3 o rings that came out, a red a brown and a hard one, anyone know what order they go back in lol
