ls1 fuel rails
those with ls1's in your thirdgen did you use the older 97-98 return feed style and fit them with A/N's to tie into our stock fuel lines or did you run a aftermarket setup like fast and aeromotive?

i used stock 99 fuel rails, with a aeromotive regulator with all bradied line from the tank, and a new steel line for the return from the regulator. seems to work perfect so far.
if you still have the original fuel lines it would be a ton easier, but i had to start from nothing

original? how do you mean? i have a set of 99 and 01 f-body. i'm just wondering if it would be easier to pick up a 97-98 vette return style ls1 rail system. you can pick one up from gm for under 200 with the fittings and a regulator where as the aeromotive regulator, rails and fittings are a little less then twice as much. this is for the daily car so i don't need to plan for any serious horsepower, i just want something that will work.
all suggestions are appreciated.

i ment the original fuel lines from the camaro....the ones that come from the tank. i didnt have any of those left, so i had to start from scratch.
i like my aeromotive setup, but i think your right, it probably would be a little over kill for a daily driver. i think the earlier style setup would work fine.
you going to have the car done for superfest?

lol... well lets just say it won't be in paint although it will be painted.
yes i have all the original lines back to the tank. i'm just looking at the typical engine bay setup. looking for the easiest setup and this is for the vert, not the hard top. the ls2 is pretty much ready to go but i don't have time to finish the paint.

I bought the regulator kit from thirdgenresource.com It wasn't much more than had I pieced all the parts seperatly. It came from them fairly quickly and has worked well with stock thirdgen Fuel Injection lines.

Here is a picture of the engine bay with it installed. I wish I had a closer picture of it, but I think you can get the general idea. The 3/8" OE fuel feed hooks directly in the bottom, and the return comes out the side, through the steel braided line and into the 5/16" OE return line. Then the single feed from the other side is the other steel braided line, going to the returnless rail.

thank you for the picture, what factory rail is that then and i assume that's an aeromotive regulator? are you happy with all of it? it looks nice.
i'm just trying to decide if its worth the extra to throw in some billet rails and aeromotive regulator or just pick up the early ls1 gm package deal. either way i still need to come up with fittings and line but the gm 97-98 ls1 return style comes with rails and regulator for under $200 new where as the aeromotive billet rails and regulator add another $150+.
for a daily driver that doesn't have plans for mods i'm not sure if it's worth the extra just for the looks. greatly appreciate the input!

The fuel rail is the stock '99 LS1 F-body rail. The "kit" that F-body motorsports sells comes with everything you need to adapt your stock steel fuel lines on the body, to a single line returnless rail. So all you need to purchase is the regulator "kit", which runs about $250. The regulator itself is a work of art. It looks good and functions well. The steel braided lines looks good and its real steel braided lines, not just the cheesy covers. If I do another LS1 swap on another one of my cars(which is likely), I'm going to use the same regulator.

this may seem like adumb question but why not use a stock LS1 fuel tank, sending unit and all. I think it should work since its internally regulated due to the returnless fuel system they used on the Ls1 cars.I was thinking about this the other day when I was trying to decide if I wanted to go LS1, my plan was to get rid of the TPIs stock return line all together, put a fourthgen tank and sending unit in and adapt the TPIs pressure line to it and then to the stock fuel rail and it should work in theory.

in my instance though i already have true braided line fixed for tpi with a nice walbro setup and my tank is new/good condition. if i were in need of a new pump or anything from the motor back though i think it would be a good idea yes.

thanks for the resonse, that also sounds nice. i'm just wondering what gains or ease of use would be over doing as i mentioned before with the original gm equipment. i'm certain the regulator isn't as nice but it would save some pennies i suppose?
the gm setup comes with the 97-98 ls1 return feed, a few fittings and their version of an adjustable regulator. all that's left would be braided line from the rails to the factory thirdgen lines and the fittings to adapt such. the big key i suppose here would be the regulators, while you save some going the gm route for a pretty much stock setup it would work but i'm sure many would want a nicer regulator?
for my particular case i just want a factory working setup as of right now with the cheapest route to get it on the road. what do you think?

I'm not trying to pimp fbodymotorsports, just letting you know I found it to be a good product
As for using GM's rail and regulator, I don't know if its better, just as good or worse because I don't know anybody that used it.

Ohh I see, I misunderstood then I thought you may have had a complete donor car for the swap. I guess thats what I get for trying to put my input in on something I just had as a brainstorm and plus I made an asumption, which I should know never to do since I work on cars for a living.

kandid, the board to search and ask for LS1 swap stuff is the conversions and hybrids forum at ls1tech.com..... lots of info there.
personally, i prefer the cleaner (and it happens to be cheaper) look of ONE fuel line going up front with quick connects between the hardline and the fuel rail.... then running a vette filter/regulator in the back of the car where the OEM fuel filter was.

that one looks like the russell adapter.
if you want to use AN fittings, it works.
personally i like the OE style fittings... they dont stand out too much like the aftermarket stuff does.

if that is the standard GM push-on style adapter, Pure Choice Motorsports has 'em. They have a bunch of lines and kits too, might have what you need. We used an LT1 conversion kit for my brother's LT1, the kit came with a 3/8 and 5/16 push-on to AN, and two pre-maid braided lines. nice stuff.

The push on connectors are also sold at AutoZone, and O'Rielly auto parts. I bought a 5/16 and 3/8, gave about 10 bucks a piece for them.

russels is a hardline 3/8" to -6 an fitting.. thats what i used for my lines...
http://www.jegs.com/cgi-bin/ncommerc...86&prmenbr=361
the other one's are the slip on ones that work like a stock fitting to -6 an.. much nicer but a bit more and hard to get in canada
here's what i did, not that its really applicable to your app but if anyone else is looking in here for options...
stock 99 ls1 gas tank
using the stock plastic lines to the 99 fuel filter... from there it goes into a T fitting where the return line attaches and goes back into the tank...
i took the stock 92 third gen line and hooked it up here...
i cut the return line and cut the evap line hooking them together by the filter...
at the front i got two earls adpaters for the stock lines to -6an hoses... i connected a hose to the evap.. ran it up and around by the brake and up into the evap cylinder...
i then made a -6 an hose with female ends ... added the compression russell fitting to the fuel rail and tightened the hell outta it... i then ran the hose from the feed line into the rail...
dont have to mess with pressure or worry about something else breaking and i have evap
the fuel filter didnt fit perfect as its straight instead of off to the side.. but good enough for me

excellent info, if anyone else has anything to add please keep them coming.
Klortho any idea what brand the fittings were, makes it easier to ask for them since my autoparts stores haven't upgraded to picture menus yet.

Hmm...I would have to check and see if I still have the packaging, mainly they are simply GM fuel line quick disconnects, or that's what I asked for. If you have an O'Rileys they are in the fuel line repair section, and I think AutoZone may have them behind the counter.

The ones circled are what I am referring to. Disregard the rusty strut tower, I had a brake booster that was leaking and it will be taken care of when the entire car gets painted.

heres where we got 'em, bottom of page. cost about a hundred bucks with all the stuff shown. you can probably get just the connectors, but it doesn't list the specific part number.
