suby fuel line

[subeylube]

Hi, I have a 2004 2litre imprezza and the fuel pump is dying. I know this is a liberty forum, but unless you have rex then no one cares for poverty pack imprezzas. Besides I think this question could apply to several other subys? The fuel pressure outlet,or pressure line, from the tank mounted pump has an unusual (to me anyway) looking connector. Its basically round and has a brown coloured tab on both sides of the connector. My question is to undo this connector is it just a matter of sqeezing the 2 tabs, or is a special tool required.

Yes I know the line has to be de pressurised first, and I have a range of fuel line quick connector release tools, but this connector is new to me?

Thanks in advance

like these?
Just squeeze and wiggle it back up the fuel line

No, theyre the ones used for the return line, like me been around for 100 years. the pressure line has a black plastic fitting with a brown coloured plasic insert with a tab on each side that can be pressed towards the pipe

Thanks for the help, I found a manual for a legacy on the net and have attached the picture of the quick connect coupling. Very clever, and simple once youve done it once. The brown tabs fitting, aptly called a retainer is designed to be a one shot wonder requiring replacement at each disconnect.

Thanks again

Are you certain about this?

This now has me worried as I recently disconnected all four fittings to my tank (pump side and assembly / filter side).

Any confirmation would be appreciated as I really do not want e85 spraying all over my back seat (I'm a smoker)

Mick the last time I replaced one of these clips was when the apprentice snapped it. And I've never had a car come back leaking fuel. When I had a gen4 the pump was out twice in a month, still never leaked.

Legend thanks for clarifying

Just seemed odd to require replacement at every disconnect. From what I saw they're pretty sturdy and firm

Thanks again for confiirming dropz

They do look sturdy, for plastic, that is. I dont doubt that you can re-use them as I did, but the manual states to replace the retainer when undone, which Subaru would want, in order to cover their backside in case of failure after handling. In my 50 odd years as a qualified motor mechanic, and industry trainer ive seen this sort of statements by manufacturers many times, and if you or I choose to ignore it then we cant expect any assistance from the manufacturer IF the part does fail.

I would not fret regarding the reuse of the retainers, but then I cant speak on behalf of Subaru.

Thank you for your interest in my enquiry re the connectors anyway.

Completely understand and agree. I remember toyota used to state that the rubber o-ring on the crank angle sensor / dizzy needed to be replaced at each rotor button change as well. Bit ridiculous I think considering it's a rubber o ring.

But in this instance I was worried due to the specific nature of the clip - ie it holds fuel pressuriser at up to 80psi ! Suffice to say we do not want this to fail EVER.

Thanks again for raising this matter

Yep got those connectors on my GT, just be gentle when disconnecting each line off the pump top plate. Definitely make sure the fuel pressure is relieved before touching them.

Once you've put the pump back together and in the tank, pressurize the system (switch ignition on) and check for fuel leaks before putting cover plate on and the back seat in. Also check after a quick test drive that fuel isn't running down the driver's side of the tank under the car. I remember smelling of PULP for days after doing all this

Yes, being sensible with these connectors is obviously the key point. They are quite a simple idea when you see how they work. Did you notice when you pulled the connector off the fuel line, there are 2 o rings inside it. Cant say it would be a pleasant job renewing them, particularly in the very cramped location in my imprezza. The pump cover is located in the boot space right up against the rear seat backrest, making access to the 2 front screws very difficult, luckily I have a very short stumpy philips that did the job. I also made sure I lubricated the orings inside the connector before refitting, to make sure they didn't catch on the end of the fuel pipe.

The original fuel pump was making a hell of a racket, and when I have a look at it, on the output end of the pump there are 2 rivets and a hole with what looks like a fine screw thread, and im wondering if there is a screw missing from the hole. The new pump is a "Denso" brand and has a different cap making comparison impossible. For $100.00 I cant complain, no noise. It is unusual, I think, that the pump should only have lasted 30,000 kilometres, which is all my wife has done since we bought it new.

We have 2 subys and wont hesitate to buy another, great cars
