The fuel system uses all Aeromotive aluminum fittings with alcohol resistant hose. It's all plumbed up except for the return line from the engine. You can see the electric Holley Black series (alcohol compatible) fuel pump,surge tank and gas tank in this picture. The electric pump only supplies low pressure fuel to the surge tank, where the manual pump on the engine grabs it and pressurizes it to 2500 psi (not a misprint, the pump is making 800 psi at idle). The purpose of the surge tank is to ensure a good supply of fuel no matter how many G forces the car is generating.

I also double checked the motion ratio of the front suspension by measuring the distance between the shock mount on the rocker arm and the shock mount on the frame, then lifting up a front wheel exactly 1 inch and re-measuring the distance from shock mount to shock mount. 1 inch of wheel movement equals a minimum of 3/8" movement of the shock all the way up to 3/4" movement, and about everything in between. This may not seem like much but it's the difference between a wheel frequency of 93.7 CPM (typical for production sports car) to 187.2 CPM (Formula Ford) so surely I can find something in there that works. I included a picture of the rocker arm for reference, but it's an old picture with the old upper control arm in place.

That blue knob is for adjusting brake bias and to the right of the steering column you can see two diagnostic ports. I got two so that one can be used for a digital dash and the other for programming or diagnostics. My HP Tuner box arrived today, I have no idea what to do with it but I understand that it's integral to the engine running.

TURNology wrote an article on my build! http://www.turnology.com/news/mark-sawatskys-1967-mgb-autocrosser/
The floor and the diffuser are are complete and installed.

But the better news is that I installed everything on the car (except rear spoiler and front splitter) and placed a 5 gallon bucket of water at the back to simulate the coolant and fuel, plus a 170 lb driver in the drivers seat then weighed the car and it was only 1450 lbs!!! It is also 50/50 left/right, surprising considering the engine is on the right. If I can add 300 lbs of ballast low down and at the back, my weight balance will be 59% on the back tires and that is amazing.
I picked up goodies for the car today-starting to get excited! The tires were only $60 a piece!

Must be getting close! Cant wait to see it in action!!
I got the tune loaded today but it wouldn't start, so I'm figuring it out still
which are you missing ? spark, fuel, or air ?
not that I can be of any help, just curious 
the engine spins over, has spark and fuel pressure in the fuel rail but it won't start. When I check the DTCs it shows codes for fuel level, flex fuel sensor and evaporative emission system. I don't think any of these would prevent the car from starting but there they are. The VATS have been disabled, I have checked all connections, the battery is new and fully charged and all grounds are firmly attached.
Do you know how to turn stuff on and off with your tuner? Can you turn off the fuel level monitor and E85 sensor or just plug in a generic value? Im guessing the computer is saying no fuel and no knowledge of fuel type so no firing of fuel injectors.
I think I know how to do that stuff but the tune was provided by someone who definitely knows that and is aware of my car and it's special needs. I'm going to poke around the program now and see what I can see.
Might want to check for fuel injector pulse...
Turns out that the Vehicle Anti Theft System is the problem, and some rewiring needs to happen to fix it. I mounted the fuel filler today. It was the only spot that looked good and didn't interfere with anything else.

Anti theft. Always a PITA.
Not much sheet metal left there! Looking good.
I am bringing this build into 2015 by creating a YouTube channel for it and will be doing video updates instead of the usual pictures and text. The channel already has over 60 videos of the build and early testing plus some videos that have never been seen. Just go to the channel and subscribe and you will be notified of updates. They won't be Top Gear of even Might Car Mods quality but I will try to be informative and interesting. https://www.youtube.com/channel/UCe50QeA3lG1KogAVpWraiIw
"creating a YouTube channel for it . . . "
Terrific ! !
Wow, that is a LOT of content! Nice job getting all those videos sorted. Is there any way to sort them chronologically? It is hard to tell what is a new video and what is an older one since they all went up around the same time.

I knew the order was going to be a problem but I don't know how to sort it. It took days to upload them and another day to sort out other things like copyright infringement. Example, on the video of the V12 on the dyno, somehow a revving V12 sounds so much like the song "Heeah Haahh" or something like that, that YouTube wouldn't let me make it public.
The car weighed 1410 lbs with driver and that is far below the 1750 lb minimum weight for the class. I debated how and where to add the weight because the current weight balance is 48% front, 52% rear and I would really like 56% rear weight. The floor was 14 gauge aluminum which was fine as long as you didn't stand on it so I decided to build a new floor out of 3/16 steel all the way from the front bulkhead to the diffuser. This would account for almost 200 lbs and I would use steel plates between the rear wheels to bring me up to the 56% weight balance I want. I bolted the plate on and reweighed the car with a driver and it is 1650 lbs with 53% in the rear. I did not take pictures of it this time but the video is here: https://youtu.be/UiWEqUQNEgU
If you go to "Playlist" the videos are in chronological order
Awesome, thanks! The channel is great - I'm planning to waste a good deal of time there today.
The club seems reluctant to lend the digital scales to members so I got a Deco Wheel Load checker from Speedway Motors (it's only $189). Here's a video of how it works https://www.youtube.com/watch?v=M6GVOVaRG6c
Interesting. I remember those from my dirt track days.
And thanks for setting yourself up on you tube.
In reply to noddaz:
I'm sure the wheel load checker is not the same as digital scales but it's the next best thing. I wish I had done the YouTube page years ago

Hey, do you think this would work on a Mustang weighting 3300lbs. I know I can't afford a high price set of scales and don't know anybody loaning them out. Thanks in advance.
