Hey. My car has broken 3 fuel pumps now.

The fuel pump works for 2 minutes, but then the pressure goes down to about 1/5 and the car just stalls, and you have to turn the ignition of and on again, for the fuel pump to work 2 more minutes.

Can this be fixed?

The fuel pump motor spins around just fine all the time, but the pressure just drops.. Somthing got stuck in there, or what can it be?

Please help me

Dunno my fuel pump broke but replacing it got it back on the road.

This is a slightly odd question but are the input/output pipes the right way?

When was the filter last changed?, it could be a dodgy relay.

Not the relay.. The pumps my car breaks is having trouble keeping the same pressure.

If i take the pump out, wire it to another 12V battery, the flow suddently decreases down to 1/5 or something like that after 1 or 2 minutes. But the motor keeps turning like it always do.

So it is something mechanical inside the pumps that is made of crap, and now i wanna know if you can fix it by disassembling it and find the problem.

Im pretty sure it happens when it gets too hot.

I wanna see how the pump is built inside.

An exploded view of the pump could be helpful i think

I did replaced my fuel pump few months ago, in my Felly.

The fuel pump itself is located inside a first cylinder, which is itself in another plastic cylinder.

Just to say that you will end up with a small iron cylinder, and won't be able to know what's wrong in it, and pray that it was your problem.

I had the same behaviour you described. The engine would start correctly, then choke a bit, a bit more till stalling dead... And you could restart it, and it did the same again.

Since I replaced it, no more problem.

DooDle..

It's ok for a pump to break, but.. after 20 and 100 km. respectively? There must be something wrong with the car i thourght, but i don't get any false readings on the voltage, so wtf?.

Dirt in the tank`?

The first pump has worked ever since the car was made i think.

Maybe dirt in the fuel hose?!

is there a strainer in the fuel pickup pipe? i've never look at one in a felicia/favorit before but i imagine there would be one... maybe it's a bit blocked up causing the pump to work harder than it should

strainer?

A filter?

yeah a filter... it's normally like a metal guaze

I just tried blowing into the fuel return hose, and its like blowing into the wall! Is that normal?

I have my return pipe uner suspicion for being damaged right now.

So if it is the pipe, and i fix the pipe, would the pumps then work again, or are they ****ed for life?

I just disassembled a fuel pump, but i dont know how to get into the metal container. Something must be broke in there right? Or maybe the pumps are made like this, to "break" If the pressure gets too high?

When I replaced mine, the problem was directly solved... Erf, kinda...

I took it for a test drive, but still, I found the car being hesitant to rev over 3000RPM, starting to choke after this rev point. I put some Redex plus a full tank of Petrol, and it runs fine now.

What I wanna say here is the pump might not handle well clogs or reduced passage in the fuel pipes/lines, and what inside the iron casing might just break due to the too high pressure it has to output.

Just a thought, I'm not an expert in hydraulics though.

What is redex?
