Doesn't look like you will be putting much fuel in the tank.. maybe a third of what it can hold..
I would try making it fit high up on the rear cover.. bike cap is ok but will it seal.. I would think this over 3 or 4 more times before cutting the cover..

The pictures are only for reference of the idea sorry for some confusion, the filler will be raised up at the top of the GRP panel so the fuel pipe will be angled upwards also. I'm not fussed about the amount of fuel it will hold as will never be full anyway  I'm sure the supercharger will make sure of that The bike fuel cap souls seal as it does on a motorbike tank and it screws up tight but I plan on testing it anyway. Cheers for the suggestions |

Well after hours of messing about tonight on the fuel filler that idea is pretty much been scrapped Back to the drawing board, this part is really starting to annoy me now... |

How handy are you with a welder? We chopped the side mount filler pipe off the tank and relocated it ontop. It's a FAR better option and fills much easier. It needs the tank draining completely and rinsing out with soap and water to get rid of all the fuel and fumes - obviously. Then the filler and breather pipes cutting and the ends welding up - as pictured here:  Then we relocated the filler to the top of the tank using the hole that was already there:  Then drilled a new hole in the top of the feed pipe plate and fitted a breather there with a non-return valve. (not pictured that, but you can get the idea). The only thing you need to sort then is presenting the filler cap and hole in the top of the rear panel. You could tidy it off with the fitting you've already got, we've just put white tape over it as we need to get access to it regularly and the presentation isn't so high up the list on a race car. Others that have done it have fitted a large screw in drain pipe attachment |

Cheers for the idea and pictures they always help, yeah I can weld so not an issue there, I did think of bunging the holes up. I tried the idea of the hole already in the top of the tank but the cover is a very tight fit and i couldnt reuse the standard mazda filler cap. My new idea still uses the motorbike fuel cap however I have just cut the flip up part out and attached it top the cap itself, so the it still sits in the outer ring but now the flip up part now allows you to just unscrew the standard filler cap which makes a leak proof seal so even if the fuel is sloshing around it doesn't leak. I've been on the hunt for flexible fuel pipe which isn't a fortune. The cbs one works out nearly £20 for 50cm's. A seller on ebay has braided pvc clear tubing and states it is for use with petrol. I emailed him asking if it comes with any spec sheets to prove to MR IVA man that its ok to use. They replied saying its used on petrol lawn mowers for the fuel pipes but cannot provided any documents to back it up. I have found the maker of the pipe online and sent them a email to see what they say about it but clearly states on there website that it is for use with petrol. www.nene-rubber.co.uk/pvc-hose.php |

Ours is as well, but that's kinda the point As you can see we've used the original cap and there's just a hole in the top cover big enough to reach in and unscrew the cap. You can always mount it so it sits flush with the top cover? |

Well long time no update but hey ho its been cold   Not a lot done at all but i did manage to spend a little time on it today. I fitted the bonnet and drilled and mounted the locks to mount it. Pretty good and were cheap from ebay too.   I've got the same locks to mount the rear panel also and plan fitting the centre exhaust from my other project. I also wired in some clear side repeaters i got from a Mercedes A class, I plan on getting some mesh and filling the corner triangle and fitting the repeater in there. I did have a mishap tho and cracked my dash pod, nevermind tho it can be fixed and i might make one like has been done by someone already. Im thinking of loosing the mx5 centre console with the gauges in it for a smaller more discreet one. Its getting there and I'm hoping with the warmer weather and lighter nights ill start to get in there more and get it finished. My other little project is taking a lot of my time up tho at the minute, see here. nescc.forumup.co.uk/viewtopic.php?t=917&mforum=nescc Well hopefully more updates to follow soon. |

Nice job on the panels.. for the top miss hole why not just glue another cap on to cover hole. and some black sealant for the other or just leave others.. Noted your rear brakes are not fully seated against the rotor might be time for surfaceing and pads.you might be called on that on IVA.

Wow it's been 4 months since I updated my build, this has been down to me spending my time getting my other project done. Now that the mx5 project is done and back on the road after 4 years of being left by the previous owner, It now means I can restart work on Exocet. I did a little work on it today by removing my supercharger set-up back to n/a whilst i wait for my new turbo set-up in which I'm having a custom manifold and downpipe made and will be using a Subaru wrx td04 turbo which should see power of around 180bhp I also sorted out the rear wiring again as I ended up rotating the fuel tank 180 degrees to make my fuel filler easier to fit. I bought a boat fuel filler and fitted it in the centre of the rear tub. Looks very nice IMO and goes with the chrome cam locks on my bonnet. Last few bits on my list are to make some mounting brackets for the rear tub and to make/remake the rear light brackets as I don't like them, then finally make the exhaust mountings and exhaust. The rest of the niggly bits I can finish off when it comes time to rebuild where hopefully no more welding or drilling will be required. Once these are done I will be stripping the car back down and sending the frame for powder coating A quick question regarding the exhaust, the iva manual states that it must have one silencer in the system and be less that 99db. I have a standard mx5 exhaust system and the centre section looks like it has a very small silencer in it, is the sufficient for the iva man? Also I plan on using a piece of flexi exhaust section with a twin exhaust tip on the end. I know this maybe a little loud but was thinking of fitting a bypass valve to it and having the valve half closed to reduce the noise level and I can open it to suit when needed. Anyone have any other suggestions to quieten it down in this type of set-up. Cheers Craig. |

My exhaust set up is almost identical to what youve described. It came in at 103db.
I ended up buying two removable db killer inserts/mufflers. Im yet to test the volume with a sound meter but it is considerably quieter to the ear.

My fuel filler I made before with the motorbike cap I wasn't happy with, because of this I decided to remake it. I decided to turn the tank 180 like others have done so that my filler was now on the drivers side to make the fuel filler hose a little easier. However in doing this I had to make a few changes as there were a few slight issues: I had to rework the piping to the tank, but was easily done. I had to redo the wiring as I had temp made up the loom for the other set-up, this wasn't an issue but had to change it because it wasn't long enough to reach the pump as it is now on the opposite side. The mounting points made for the fuel tank are for it to be fitted the normal way (filler on the passenger side), this means that there are now only 3 mounting points for the tank to mount, I will have to add one more for the n/s/r. The tank doesn't move or flex at all but it's just in case Mr IVA man decides otherwise when seeing it from underneath. This it the fuel filler i went for, was around £30 from ebay and seems fairly good quality. I got the 2" filler size but others are available.   I measured up the centre of the rear panel and used a larger hole cutter to make the main filler hole, then I needed to mark and drill the 3 mounting points. Before doing this I unscrewed and then re-screwed the filler cap so that the fuel letters were straight when the cap was tight, then unscrewed it and drilled the holes and fitted it.     I'm really pleased with it the only slight downside is no breather pipe connection. I'm going to order a cbs ultra flexible filler pipe and make a t piece at the top so that I can refit the breather. Has anybody fitted something similar but not used the breather pipe, if so what did you do. I could cap it off but filling will be slow and may spurt back out when filling. Any ideas welcome. |

I'm sure the supercharger will make sure of that
