Just thought I'd post this if any of you are doing MSA events. Scrutinieers are looking at the way our (MX5) roll cages are fitted and the fact that we have gaps from the boot area (where the filler pipe is) and the cabin, particularly if you have cut the cover to fit the roll bar (which is the only way) I have put fireproof ali tape over mine which is ok as a stop gap (no pun intended) but they will be looking at this more closely next year. To be fair this is not new - the reg stating that there should be a solid partition between fuel areas and the driver have been in place for some time! It seems to be a bit random on when they check or not and today it was just a friendly reminder. I did read (on Nutz I think) that someone was actually pulled out of a class because of this?!

Hi guys, I was also at the event and I must say I was some what defensive when the scrutineer started picking faults,but once he come off his high horse and explained it clearly I was in agreement with what he said. As others have already said it's to do with there being holes in the bulkhead the particular 2 on mine were where the battery loom goes through through the firewall behind the drivers seat and as said before, on the rear tin deck cover. So he said and I'm leaving this wide open as I'm sure they change there minds! That I need to at least block those 2 bits up for him to be happy. But also advised to shine a light through from the boot through to the cab to see where light comes through. But I'm not too sure how the can police that really ?
Just thought I'd share what the scrutineer said to me.

Has anyone fallen foul of this yet this year? I only ask as I'm entered in the Great Western sprint on 25th . Need to know whether to fit the roll bar and bucket seat/belts and risk exclusion or stick with stock seat and belt?

If you're in a road-going car class, you cannot be excluded for not having a rollbar & harnesses as it's a recommendation not mandatory. Check the regs though as there's usually safety info.
I bought a MK2.5 track car with a TR Lane rollbar fitted without a harness bar, but with shoulder harnesses fitted to the lower rollbar mounts....
So in the event of a high load on the harness it would've potentially resulted in broken collarbones &/or compressed spine plus there was no barrier between the boot/fuel lines & passenger compartment.
So I went to a local steel tube supplier (who happen to supply Custom Cages around the corner) & got an offcut for £5, cut & scalloped the ends then got a mate to weld it in- tadaa! Harness bar! Whilst the rollbar was out having this done I fabbed up a couple of thin steel plates to block up the holes. Bolted these in using existing holes then back filled the whole thing with firefoam. The only trick bit was making small conduit to carry the wires thru.

I have a TRLane rollbar and no rear carpets. In roadgoing teh scrutineer doesn't care about the rollbar it is the separation between the fuel and the passenger compartment.
I just put fireproof tape over the holes and that passed. As long as they can see no light to the outside from looking in the boot seemed to the the check for at the GWS last year.
I think the scrutineers are a more experienced bunch at that event as it is a round of the British championship. I will post some photos on Friday. If the gap is too big or awkward for tape fireproof expanding foam from any building supplies place will do the trick. As the scrutineer said there are no standards for teh material providing the barrier. It is to prevent fuel leaking into the passenger capmartment rather than fire.
Alternatively box in the fuel filler pipe
discussion from last year
"There was some discussion at the Great Western Sprint between competitors and scrutineers about the holes cut in the bulkhead for rollbars. I've taken photos and submitted them to the MSA for clarification and they have agreed with the scrutineers that these holes must be sealed. Here is the complete response:
The regulation the Scrutineers will be referring to in this instance is J5.2.1, which in simple terms required the driver/passenger compartment to be isolated from the fuel tank and fuel system (filler necks, fuel pumps etc.) so by having holes in the rear bulkhead of these vehicles would not comply with this regulation. So the holes will need to be sealed, there is no specified material for the sealing providing it is a non-flammable material capable of preventing the passage of fluid or flame.
As a result, I would recommend that you seal around the rollbar in some manner to avoid this problem in the future. The suggestions offered by the scrutineers were to either bolt/weld a plate over the gap or use fire-retardant expanding foam to seal the gap. Both were stated as acceptable by the MSA. I would suggest that J5.13.1-2 is an exception to J5.2.1 and so it may also be feasible to replace them with braided hoses, but it would probably be easier (and cheaper) to seal the holes."

Thanks for the replies . They've cleared up any ambiguity . I'll make do with stock seat/belt for the GWS and fit rollbar etc after when I have more time .

Very interesting thread, and something that has occurred to me the more I strip out the car and particularly when I fitted my roll bar....
Being a smoker with a terrible sense of smell.......and noticing how I am just in front of the fuel tank and particularly the rubber filler neck!
I like the idea of expanding foam, but a note of caution regarding running cabling through some types of foam....It may react with cable jackets in a corrosive way.
eg. the NICEIC were very hot on not letting mains cabling in houses run through any polystyrene as it eats the protective jacket.........exposed cabling= fire hazard!
I'm tempted to do this, but am now thinking along the lines of conduit through the foam around the cabling then some kind of sealant (maybe even silicon) inside the conduit?
Anyone any ideas/better knowledge on this?

Fireproof tape seems to be the best solution, cover up all the holes, and always have a roll in your toolbox!
