crossfire injection parallel plumbing

Hi

I'm planning on parallel plumbing my TB's soon ('84 corvette), along with the addition of an Aeromotive vrfpr. Can anyone tell me what specific fittings to use with the fuel send and return lines going into the vrfpr? I've heard possibly a "compression fitting"? Also, what is the best way to install? Thanks in advance.

Using the Aeromotive 13301? You will need to remove your fuel pressure regulator diaphragms on both TBI units and use a block off plate.

plumbing the 13301 isn't too difficult.

Re: crossfire injection parallel plumbing

Thanks for the reply. Yeah, I'm planning on buying the block off plates from TBIPARTS , along with a few other items very soon.

The 13301 install itself seems pretty straight forward, and I've since aquired a partial list of fittings, etc. But what I'm curious about are the stock feed and return lines. If these lines need to be cut down, spliced, (it would seem they would) and if so, what fittings are curently being used for running the feed line into the Y block, and for the return line coming out of the 13301? If I'm misunderstanding something about how these lines would be run, please let me know.

Also, if anyone has pics of how they did theirs, that would be great.

I am TBIPARTS, haha!

Measure the outside of your fuel lines. Return and supply. I have all the Earl's part numbers that you need to tap into your existing factory lines and also to tap into your 13301. I either started or added to a number of threads on TGO regarding braided lines and -AN plumbing, etc.

I ONLY use Earl's plumbing now. I have used a mixture of Russel, XRP, etc, but the best price on the net and in my opinion the best quality is Earl's.

When you're ready to do your project go to www.anplumbing.com They are the #1 Earl's store and the best prices. How-to videos and everything.

I cut the lines right at the AC compressor. I will post a pic. then I used two compression fittings on the hard line. To that I ran my Aeroquip lines. I wish I could find my receipts for part #'s!
