Fuel Filler & SVA

[robinj66]

Can anyone tell me whether it is a requirement of the SVA to have a restriction in the fuel filler which only allows the use of unleaded fuel. Dunno where I got this idea from but it's now bugging me. Help please.

No, cos your engine could still be running on 4 star

You only need the restriction if you are subject to a catalyst emissions test.

So that's if your engine is post '92 or post '95, depending on what it came out of.

Section 15.2, part 1b in the Blurb.

Hi Robin, Simon is right regards the book!

But I was advised to fit one by Friendly MOT garage.

2 reasons - 1. The Inspector MAY say you have not controlled the grade of petrol that can be put into the car- therefore emmissions will alter ( remember we are at the mercy of 'their' interpretation' of the regulations - and it only costs a tenner!

2. - If your missus sneaks out in the Cob, and she tops up the petrol to hide it's use - SHE will at least put the correct grade in !!!

Hi Mike, I've got a nice SVA friendly lockable Aero cap for sale if you're interested?
Like brand new with all the fittings.
£40 for a quick sale over £70 in Europa.

Kev, I do like the sound of 'lockable' , If you still have it, and I can make the run next week, bring it along and I will have a look.

The pilgrim tank has an "anti-syphon" baffle fitted but the locking cap will stop anyone adding things to your petrol. ie sugar etc

Thanks for that. Unfortunately I only have 1 & 1/4 inch gap between the top of the filler neck and the body. I had a lovely aero cap (locking) but the integral funnel was too long to fit. The unleaded restrictor fits in the bottom of the funnel.

I say "had" because I've chopped it down and it now fits a treat - still locks etc but there's no easy way I can fit the restrictor as things stand.

Reagarding the missus driving the car - mm interesting thought but she knows the death penalty applies to offences like that!

Robin,
If your car doesn't need a Cat, you don't need a restrictor insert.

It's there in black and white in the SVA manual, and it's not open to interpretation.
However it's sort of hidden in the "Design & Construction" section, not the "Emissions (P)" section.

Any vehicle with an "emissions effective date" pre '92 does not NEED to have a Cat, though some (Volvo etc) did.

Some models up to '95 don't need a Cat either.

You can therefore legally run your Non-Catalyst Equipped engine on any flavour of petrol you want - though these days you'll be hard pressed to find 4-star anyway.
