Hi All,

I bought a fuel pump (cylinder), for my MK1 Focus, went to replace it, but when I go to close the housing to the pump it won't fit, it seems like the rubber seal is too far down, but I can't see a way to raise it without it popping off.

Any ideas please?

Hopefully someone has replaced this?

Thanks

Do you have any pictures?

Sure, I'll take some tomorrow

Here's the pictures

Maybe put the old one on. Or glue the new one to the pump in the correct place

Been there done that, certainly got the t shirt, will look out for any photos I took at the time.

Oh ok maybe try spacing it out somehow with the old rubber seal maybe hard to say without being there and seeing it myself if you know what I mean

Apologies, I am trying to remember back as it was quite some time ago that I did mine. - What exactly won't go back together?

This was mine assembled with the fuel feeds:

and then with the top part of the cover removed (so just the pump and top housing):

Looking at how much of the electrical connector of my pump was sticking out through the top face of the cover, it looks as if in your photo of the pump in the top housing the pump just isn't pushed through enough?

Sorry, it isn't clear to me what you mean by:

Thanks guys, much appreciated.

Basically, I would like to know how this rubber seal goes back, as I didn't take a "before" picture.

Unfortunately (I just checked) I don't have any photos specifically of that rubber seal area, sorry!

However, I also don't have any recollection of it being a problem... have you tried the "just shove it" approach? I think it is a fairly tight fit but I'd think that the pump and rubber sleeve just push complete up into that housing plate?

Didn't think it should be that tough, I'll try again

Cheers

Don't overdo it (I wouldn't want you to break it) but I'd certainly give it a try. As I say I don't remember it being an issue when I did mine many moons ago..
Let us know how you get on [emoji106]

Sorted, the rubber seal looked like it went one way, but upon changing it round and with a bit of fiddling, it fits aok.

Added petrol, I can hear the pump, but unfortunately it hasn't fixed my problem.

Took pump out again and there is fuel in there.

Can anyone suggest something else to try?

Glad you got it fitted mate [emoji106]
I'll go take a look at your other thread now [emoji16]

Got some "Cold Start" and it fires up, but won't last, so that rules out spark plugs, there is new fuel, the pump pumps, the relay and fuses are ok, the only thing is that the fuel gauge says full and it's not, so will refit the pump again.

Any suggestions?

Thanks

Pulled the fuel pump exclosure out again and did some testing.

Hooked up the battery direct to the pump and it doesn't push any fuel out of the top, it just bubbles a lot, like there's something blocking the tubes, but can't see where!

Strange, took everything apart again, put back together and it pumps out the "white" nozzle fine.

Put back in tank, same problem.

Can rule out the pump/sender, as 100% know it's pumping out of the "white" nozzle

Also checked resistance on the float and looks fine

Maybe some sort of air blockage?

To reitereate, "cold start" works for a few seconds

Not sure what to check now.

Anyone know how to check the fuel pressure / where the bolt is, like Scotty says? (1min 20s)

 

Adding more fuel (at least 50%) fixed that problem.
