I read that an L33 is returnless system
My L33 came with two fuel lines, that were cut at motor


also looking to tank and I see alot of variation in price

does this tank get me what I need, looking for 400hp max from the L33

That tank will do everything you need. You'll need to go to a single line returnless system. Maybe as simple as a fuel rail change or modification.

here is the lines that were on my engine
I'm wondering if one was a vent for emissions and not actually a return...just a guess

Yes, it looks like the black hose is an evap line. The green cap is where you can test the system.

I did just go and look to see where connector on black line goes, it is on top of intake right behind throttle body
so some sort of emissions but definitely not a return line

I had just seen the two cut lines beside each other and thought one was return line

I have basically the same system on my LS2 400hp for 4years with no issues. I would suggest not using rubber line the full length of the car. Tanks inc makes a lot simpler sending unit that doesn’t require any set up for about $50 more then the one in that kit.

thanks for the help, its getting a bit clearer what I need

one other question
can I run the entire EFI tank setup, and then just use the bellow for regulator and go carbureted
it does say up to 255 lph pump, and at only 400hp I don't need that much pump when I do go EFI
I have so much to do on this car I had a thought of going carburetor on the LS to shorten the learning curve and go EFI later...just want to know options, probably wont

A stand alone harness is pretty easy to install, you already have all the components for the EFI ? Mine is a stock harness and ECU reworked by Speartech, before everyone was making standalone ones. I told them what I had and they flashed the computer with a basic tune. I ran it that way for 3 years never had a problem. I put it on a dyno in 2015 just to make sure everything was safe, the tuner said the tune was pretty close just a little fat. He evened out the fuel curve and haven’t touched it since, runs great .

regarding the CPP kit vs others like that from tanks inc

The reason I was asking about the CPP kit is it is about half the price of same components anywhere else
I do not mind paying more if there is a legitimate reason too
are there shortcomings to the CPP kit

The CPP kit is a tanks inc, I think the Holley kit also uses their tank. I just got the parts I wanted from summit. I always thought it was funny that you can usually get the parts cheaper from a 3rd party then you can from the manufacture. My TCI kits were cheaper off of flebay . That was before I knew about Tim’s hot rods. That is a good price for all the parts and all the fittings.

The only drawback to that setup is how they have the flange mounted / sealed to the top of the tank. They include tiny orings to go under the machine screws. Sounds good right? The only problem is there is no receiver groove for the online to go into. Therefore if you tighten it like it should be tightened the I ring will squish out. I used copper washers with a fuel resistant sealant in mine.

My tank for a different car was $50 less through summit but the pump and everything else was less through tanks inc. I have a in tank pump going to a aeromotive regulator feeding a carburetor. I just finished the install and will hopefully try it in spring. The regulator I bought can also be used in efi with the swap of the spring ( included) of interested in the p/n message me and I'll look it up.

Rebob that thing looks like a nice clean setup!

Hope this helps

I just installed this kit on my 65 recently. I would highly recommend it. CPP did tell me that it is a tanks inc setup. I also have an L33. What intake and rail do you have? I swapped on a TBSS intake from an 09 that performs better. I know most truck intake setups(including the TBSS) have a returnless style system so I just had to plumb it to the rail. The corvette filter/regulator takes care of the rest.

As far as engine management and tuning. I would stay with efi. You will need a lot of parts for a carbureted setup that you won’t need if you go to efi later. To that end, I would highly recommend the Holley Termjnator setup. It seems pricy at first glance but when you see it includes a harness, it becomes more reasonable. If I had to do it again, I would also go with a DBW throttle body.

I’m not sure what brand filter CPP uses but some people have had issues with them right of the bat. Some where I read only use Wix or AC delco, I’ve always used the Wix their cheaper and have never had a problem. Like mentioned before, I didn’t use the little o rings but used sealer on both sides of the gasket.
