Fuel line through bulkhead fitting in shock tower?

To anybody reading, they are pretty slick, but expensive.

Oh ok I was just pointing out about the NHRA rule that the fuel line cannot be with 6 inches of the bell housing area to pass tech.
But a street car can do whatever you want. Thanks for the info.

Kent, you might be interested in the mount I made to put the Hyperspark coil on the end of the cylinder head. Requires the low mount bracket for the alternator.

That is a nice mount. I bought your BB alternator kit, not the low mount one. I fabbed my own for the Hyperspark coil that mount on the Torker II. Well actually I just used one mount hole and drilled another through the coil mount and used the holes that were already in the intake.
 
Here is what I did down in the rocker panel. Basically the same idea where I have a large hole in the rocker panel and then use a small bolt on plate that holds the bulkhead fitting.

It can be, however it needs to encased in steel where it passes by the flywheel/flexplate. You can see the pipe I used, has some yellow spray on it.

What wall thickness is the pipe and the outside diameter?

It’s about 2 1/2” diameter, 1/8 wall thickness and 16” long. Enough room inside to easily fit two 3/8ths fuel line. I put plastic pipe couplings on both ends (male) so the fuel lines couldn’t run on the ends of the pipes.

I just did this yesterday. I mounted it forward as the NHRA rules say that you should not have the regulator or connection within 6 inches of the firewall. It would have been easier where Andy did his. I have 1/2 inch hard line under the car. That is just a gauge not a regulator.

I'm trying to figure out your fuel plumbing. It looks like you have two pressure hoses hooked up to the Sniper and no return line. Is that correct? You should have one pressure line and one return line.

I am using this back by the tank with the return back there. I am rethinking the second fuel line as it interferes with the air filter base. I have -8an to the bulkhead and split into 2 -6 lines to feed the EFI. I may just use one -6 line and see how it goes. If it is fuel starved, I will change to 8. Probably don't need to overbuild. Also my understanding is that with the sniper you do not need a regulator after the efi but on the more advanced EFI, my system would not work.
 
Okay, that should work okay. You're going with a dead headed system with just the high pressure line running up to the engine from the rear of the car. That is how a lot of OEM cars are these days. You don't need two lines feeding the throttle body, just run one line to the rear. You usually can't use the front fittings due to air cleaner clearance. Is that a base Sniper or a Super Sniper? If it is a Super Sniper then you can hook up a pressure sensor to your Y block and data log the fuel pressure. You can also data log oil pressure and one other pressure input such as brake pressure or pan vacuum or transmission line pressure.
 
I have the super sniper. Additional sensors will come later. For now, I want to get it running again with efi. It has only run on a run stand with a carb and coil and ready to run distributor.
 
Good deal. You'll really like the Sniper once you get it running. Having all that data at your fingertips is really nice. Do you have a laptop so you can tune in the car? If not you can always pull the SD card and sneaker net it into the house for program changes. The sensors from Holley are expensive (Cherry has less expensive ones) but it is cool to have the additional data. I had some sensors harness built by a harness company so if you want to hook up multiple sensors to the Sniper just let me know. Holley hasn't gotten around to designing a sensor harness yet so I had some built.

Thanks I may consider routing that way. Have to look at header clearance first and oil lines to accumulator.

What is the reason for the plate? Is it a stiffener as well? I just mounted a thread together type bulkhead fitting in the existing metal.
 
The plate is so I can get a wrench on the fitting. There is no access to the backside of the rocker panel.
