Default Boomba Racing Fuel Rails Install Help

So I orderd the fuel rails today and I'm trying to figure out how to plumb everything that way I can get all my fittings and hoses.

Here is a diagram that I found and am wondering if this will work since I will be running a AEM FPR and wont be using the distribution block for the stock fpr that comes with the fuel rail kit.

You could T the return so you have a single feed to the fpr.

Are you going to run new lines straight from the pumps? Or just reuse the factory hard lines?

Stock id is 5/16. you could go bigger but it wouldn't do much if you were going to just reuse the factory hard lines.

Go get some string and mock it up. I don't know your budget or what type of line you want. Stainless braided, AN fittings? Brass or stainless barbs and T's?

A good cheap hose should be a SAE J30R9. But really depends on what you want done

I didn't buy any hose. I had a great deal on an aeromotive FPR and the seller gave me his SS teflon lines and all AN fittings with it.

Buy more than what you would need. I would say at least 8ft, to be safe get 10ft.

The lines are $3.50 per ft here :

Just checked how my perrin v1 are and it uses about 11 feet. look them up and you'll have a good idea of what they look like. That would be with new line to the fire wall hard lines

Which one is the return and the supply on the fuel rails themselves. Cuz in the picture above they are parrallel but the actual product they arent. One runs ontop of the other.

It doesn't matter, but I would think the feed in the top and the return out the bottom would be cleaner and make more sense

Well I got everything put on however the fuel injector wiring clips don't fit on because the fuel rails are in the way. And to top it off I can't fit the front injectors in because the cam sensor is in the way

Nope you can turn them about 25 to 30 degrees but it's not enough to make a diff. In just gonna hardwire them in with heat shrink and everything.

I had to clip off two small pieces of plastic on the injector wiring clips to make them fit under the Boomba rail. Other than that, I had no issues with the clips fitting.

I prefer series...
Less hose, less clutter, less misfires, less vapor pockets.

Bringing this thread back to life I'm looking at this amazing photo that was drawn for the OP and Im going to do it myself but with Perrin Top feed rails. How did this set-up work out for you and did it really matter which one is feed and which one is return?? I have a AEM FPR that I'm installing it also has 2 pressure ports (or inlet) and then one out thanks anything will help

Dom I keep seeing you saying series is better than running parallel. You should give us more insight in this topic.

Why would parallel lines cause misfires, vapor pockets ?

Thanks

I run my fuel system just like this and its been working great..
But i would also like to know more about setting up series rather than parallel.

There are a bunch of arguments to both sides however I have yet to see good enough proof to persuade me that series is better then parallel or parallel is better then series. I have yet to see a diff in performance between the two.
