Fuel filler neck legit?

[DiyNutJob]

I just received a very reasonably priced china fuel filler neck for micra k12 from an ebay start up. The interior bits are not same as the original unit. So, can anyone tell me if this is OK for use? I think most of the sellers are selling this exact same thing.

On the original unit, the fill pipe has a small flap that opens to accept the petrol station nozzle. Then, the tank vent pipe vents separately from the fill pipe. On the new unit, both the fill pipe and vent pipe share the same space behind a face plate. The big hole on the face place takes the pump nozzle. The small upper holes enable venting. The vent pipe joins the fill pipe immediately behind the face plate. Is it a problem for the vent pipe not be given an outlet isolated from the fill pipe?

Why not buy a proper one from a U.K. main dealer? Make sure you tell your insurance company about this non OE part.

They don't make this any more. Next, you will be saying: why not get a new car?

Even if it is available, it makes sense to you to buy a £300 part for a car the insurance will write off for £500? According to internet experts around here, pattern parts are fine for the insurance.

Anyway, I think the bits in the oem neck enables the auto shut off to work for the petrol station pump because the pressure built up in the fill pipe is not immediately vented as this unit does. I am guessing there is no rule that says the car must have this feature. This would explain why german made units appear similar to the chinese ones.

The job was a fail. The china neck didn't fit. Will be returning that for full refund because item wasn't as described. Found a couple of places that sell the genuine part. One place wants £240 for it. Presumably VAT and import duty go on top of that.

There is an oddity. The fuel gauge says empty, but the hose below the filler neck contains fuel. This seems to suggest the tank is full. In that case, the level sensor in the fuel pump might be defective. Will have to add 5L of fuel by hand to see if the level changes. If not, then at least it would be safe to drive to the petrol station to attempt a top up. Failing to top up will pinpoint the fault to the level sensor.

Why is it a surprise? Think before you answer. There might be a sting in the tail.

After examining the original filler neck more closely, I am concluding the aftermarket ones are legit as long as they fit. The original neck also allows the fill pipe and vent pipe to share the same space behind the face plate. The only difference is the OEM unit has a self closing flap for the petrol station nozzle. Nevertheless, both the fill and vent pipes remain permanently vented through the smaller holes on the face plate.

A full refund was obtained for the ebay unit while I am getting to keep the unit. But, I don't have the equipment to bend the mounting bracket into shape so that it could be used. They used thick steel.

Currently returning an aliexpress unit because that didn't fit either. The bracket was easy to bend but the neck was too short. I might have lost money on that because bending that resulted in marks and lost paint.

I no longer have faith on the after market parts for japanese cars. China parts for my E46 were all fine in the past. Those people who think genuine parts are better are justified, at least for the micra.

So does that apply to every aftermarket part including the ones that you have said would invalidate your insurance? Steering parts? Brake parts? Suspension parts?

Didn’t you once say a pattern cam cover would invalidate your insurance?

If you are concerned about invalidation, then you should talk to your insurer. If you gain some insights, then share with us.

Insurance is a for profit business. I am guessing their pay out rate is a bit like the pay out rate from casinos. They will pay out less if they are risking making a loss. If they really want to, they can find ways to invalidate, and casinos can find ways to kick you out if they don't like your winning even a small amount. I got kicked out by a spread better for not losing. On hindsight that's the best thing that happened to me because use of leverage is a guarantor of losing.

In this instance, the context is the filler neck. Given that the majority of the available after market supply are designed the same way, there would be lots of people running around with them. Some get away with no invalidation, and some get invalidated is my guess. It might have something to do with luck. No insurer will reveal their secret formula. But, it's reasonable to assume profit has something to do with it.

Buying a luxury filler neck doesn't appeal to me. So i will sand off the rust and bumps on the sealing lip for the cap that was probably the cause of micro evaporation leak and live with the old unit.

You’re the one who was constantly bringing up the issue of insurance being invalid due to the fitment of a non-OE part being fitted. Why were you saying that? Can you show us some evidence of insurance being invalidated due to a non-OE part being fitted? I’m not talking about silly boy racer spoilers, wider wheels, sports exhausts etc or stuff like that, I’m talking of everyday brake, steering, suspension components etc. and not so-called 'performance' replacements. Just one example will do.
