If it were my bad pump Id be at the breakers getting a used one out of a low mileage car pronto.

A call/visit to a car parts store and a consultation with the guy with the catalogues should quickly determine which pumps are common to what cars. Or ask Toyota.

I found out the MAF sensor is common to my sons 2000 ECHO and my 2009 Yaris when his CEL went on for a year and we couldn't fix it. A swap of the sensors and his code went away and mine threw a code. So at least we KNEW what the problem was.

A friend borrowed me a knockoff of the Denso pump. It looks almost the same but the smaller holes inner diameter is smaller, I don't know how this will influence anything? It came out of a Hilux. I have already sourced a proper pump with the whole assembly, used for about $60. I can have this China pump for $9.. how much do I love my car?

But seriously, If this cheapy pump solves my problem I know that buying the proper thing will not be a waste. I spoke to a mechanic at Toyota and he reckons that because I drive my car and my fuel levels are generally low (2 Bars mostly) that my pump wasn't getting adequate cooling from the fuel AND that the pump would suck up all the gunk lying at the bottom of the tank. Could this have caused the life of my pump to be shortened? It's just a theory..

Anyhow, I'm gonna embark on my quest this weekend again and will let you guys know what I find. It's not the most fun topic but I sense the end is near **

My vote is for the used pump. No China pump for me!

Me too. 60 bucks for a used pump isn't bad at all.

That pump would be fine. The small hole just feeds a recirculating device that keeps the crud moving around in the tank. Now that you know how to get in there, if the Chinese pump fails you can easily replace it again.

Re driving around on an almost empty tank.

I agree with your mechanic this is not wise for the reasons he states. Also a near empty tank is going to condense water on the bare metal surfaces...not good!

I hope you are able to fill the tank from now on!

My phone was sadly stolen yesterday so I cannot take photos, but, I have found something yo'...

Coming back from work today my pump made its usual noise, very intermittently. I decided to just 'try' the China pump but upon removing the OEM one I found the o-ring was completely stuffed up somehow. It wasn't like this a few days ago when I first took it out which makes me wonder.. Maybe that is why it ran perfectly for 2 days before the noise returned? Did I install it wrong? I feel if I replace the o-ring and reinstall the OEM pump my problem will disappear! Apparently with a torn o-ring the pump sucks in air which can cause a noise. Do our pumps work like that?

Thanks guys, I will make a plan tomorrow to get an o-ring at Autozone. Will let you know how things go :D

EDIT: Online they reckon I must lube the orifice where the o-ring goes with petroleum jelly? Vaseline??

You are supposed to lube the o-ring with gasoline when installing it.

My mistake :( I'm gonna get the o-ring replaced today and install it properly and hope for the best. The pump still works, but I've decided to push through for a bit and will rather buy the used Denso later on **

I found a good read on the internet for anyone that is interested in how the pump works and how failure can occur : HOW A FUEL PUMP WORKS

My situation matches all the requirements for busting the pump. I know my sister completely ran out of fuel a few times while borrowing my car and it all just makes sense on how this can ruin my day haha

I have one more question guys, I do remove the EFI Fuse and crank the car a few times, but I still have quite a lot of fuel running out that pipe on the top when I remove it, is this avoidable? Thank you **

I have this same fuel pump hum in my 2007 lb. It only makes the hum at a fully warm idle. If i even tap the gas so it goes up to 900 rpm or so, the humming stops until it settles around 600 rpm again. I have a new cheaper pump ordered but it will take a month to get here. No other shipping options were available. I drive about 1000 kms a week. Should my pump last the remaining 4-5000 kms that i will need it for?
