Where is the best place to get fuel lines for the LT1 swap?

LT1Intake is unavailalbe due to moving, and z28 R I C E R has disapeared as far as I can tell.


Any suggestions?

amusing how r i c e r is considered a swearword! hahaha

ask or search around on the alternative port efi intake board. I think a few of them LT1 intake swappers are using -an fittings and i think that sucks because you can't swap rails from another LT1 if you ever need to but it would work. One or more LT1 engine swappers here are using just fuel injection hoses and clamps but that may have more of a risk of having a leak.

I made my own, you can get the ends that fit the LT1 fuel rail for about $10 a piece, some FI rubber fuel line about $3 a foot. There are several places that can crimp the ends on for you, and find some that fit the hardlines that come from the tank and you'll be set.

I used barb fittings and the stock 4th gen plastic lines. heated the plastic line and inserted the barb fitting. we had to cut the plastic to remove one of the fittings one time, they aren't going anywhere.

Klortho, what would some examples of places that would crimp lines? I tried going that route before but the local clowns at the auto stores/tractor shops knew nothing. I even called up a couple speedshops/raceshops that were out-of-town.

Klortho

I found a NAPA that did it around here.

RaGe

Any part numbers for the ends or any specific way to find them?

I like the melting the plastic lines idea but my parts car is already gone.. but that does sound like a reasonable option and I'm sure I could go get the lines cheap. Did you have to bend those lines much or did they fit well stock shape?

I'm not keen on the double clamps FI hose setup, but I will use it if I'm desperate enough!

I wish I could still buy these suckers done.. Would help for the overall clean install.

Klortho

You need two sizes, 3/8 and 5/16, O'Rileys has them in those sizes. I've been running the claped FI line for almost 5k miles, no leaks whatsoever. It's only a temp setup until I can get a full set of lines made.

RaGe

I'm tempted to go your way since you do have 5k miles on it... maybe until I could get some braided ones later or something.

Are they qick disconnect lines, or just give the size and your all set??

If you use FI clamps and the proper barbs it wont be a problem. I have mine Temp. set up the same way and if your carefull it will work fine. Im just waiting untill i can get braided lines as well.

Modifying the LT1's fuel system for third gen use

This article explains in detail of how to convert it. I ordered my lines from Pure Choice and they worked out great. I ordered mine a little bit long, but that's ok. They were very friendly and helpful with getting me the right kit and fittings. The already have a kit set aside for the LT1 in our cars. Pretty cool. Highly recommend them.

Klortho

Geeez, for $100 you could goto a NAPA or somewhere that makes up hoses and probably get a set of rubber hoses with the right quick disconnects made for 30-40 bucks.

RAGEman

True, but what's an extra $50?I just like to do it right, and look good too.

Klortho

When you are doing a swap on a budget, $50 is $50.

RaGe

I'm on a budget but didn't want to skimp on fuel lines.

I think John @ LT1 intake (must have sold it) was originally around $95 for rubber lines.

Scott @ LT1 itnake (new owner or something) is selling me braided steel lines for $135 shipped.. he's been very helpful and I'm glad I was able to get ahold of him.

Can't wait to get this car running!!!

the O'Rileys here said they didn't have anything like those ends. do you know the part number?

Klortho

I got mine on the floor where the fuel line repair kits are at. Sorry, I bought mine over a year ago and don't remember the part numbers.

mliers

I used Pure Choice Performance lt1 fuel line kit. Here is the link Pure Choice Performance Plumbing I think it ended up costing me $100

do those lines from pure choice connect to the fuel rails on the LT1 and the hard lines in out cars without mods, or do mods need to be made?

mliers

No mods at all. Hooked right up to the stock lines and the quick connect fittings hooked right up to the lt1 fuel rails. Very nice quality lines as well.

i called pure choice and they want to know what type of fittings are on the stock fuel lines. i'm pretty new at pluming stuff, but he said something about wether its flared or o-ring....any ideas? i have a '88 firebird w/ 2.8 mpfi...5/16 return and 3/8 feed line. i would take a wrench to them, but right now it's still my daily driver.

mliers

Should be flared fittings

mliers

Actually I take that back I believe they are o-ring.

eagle_eyes

iTrader: (3)

well, i had some spare time at work yesterday, so i went out and took one of the lines off. obviously, o-ring fittings use o-rings, and i don't know what a flared fitting should look like, but mine uses an o-ring...it also flares out on the end, so i'm ammuming it's an o-ring fitting.

Bruce at Hawks 3rd Gen offered to make me fuel lines for an LS1 install, he may do it for LT1's as well.

i ordered some from pure choice...they knew what i needed...just needed the stock fitting type. they are already here...just at the fed-ex location in town (missed the delivery ). but i ordered them on tuesday, so it's pretty fast shipping. they were $99.95

Huge thumbs up to purechoice. Very helpful and friendly. I ordered mine on Friday and had them Tuesday. Worked perfect.

Im building a LT1 and so far have elderbrock preformer head and elderbrock preformer cam, I want to know what size injectors will fit this set up best? thanks, for all the GREAT info in ALL these treads...

Klortho

Edelbrock makes a head for the LT1?

ACCLR8N

iTrader: (8)

Yep, and they also released an air-gap intake in both LT1 and LT4 port configuration. But you won't like it.

Firebat

iTrader: (7)

Released, but nobody has seen one show up at their door yet. Rumor is they won't ship them out until the edelbrock LT4 heads are ready. The LT4 intake by edelbrock is to accept the 7777 race gasket, which means it should have bigger ports than the stock LT4 intake. The air-gap might suck because it may take away plenum volume. Who knows, nobody has seen one yet on a LTX.

Blkdth87

on my ls1 i got the factory fuel line, cut off the metal quick release clamp that was going to the factory fuel rail, and i had a hose/fitting place crimp on a high pressure hose, came out great and looks factory!! i only spent like 20 bux for the hose and crimping... not much considering...

zmack28

yes elderbrock does make the heads for the LT1. I dont know how it will turn out, but I will soon find out. Im gonna get it dyno'ed once its together. will let you know what it does.

So anyone have recommendations on the Fuel injectors?

thanks

26lb stockers, 24 if its a batch fire '93 lt1. Not having seen any flow numbers the performer line are usually emission legal mild improvements.

At least the link above me works in this thread!

I put a 94 LT-1 (383) into my 1983 Z28 Camaro. I swapped out the hard fuel lines and gas tank out of a 1989 GTA Trans am I parted out. I got 2 quick disconnect #6 an connectors from one speed shop that slip right on the fuel rail barbs, and 2 connectors for the 89 GTA hard line ends, which end in a o-ring, and ran about 7' total feet of #6 braided stainless to connect it all. Cost about $100.00 bucks, and looks sweet!

fullsize fun

Just to let you guys know for future referance I had a Lt1 with the edelbrock LT1 heads and a ZZ4 cam and I made 275 rwhp and 300ftlbs in a 94 caprice with a mail order tune

I made a video on this exact thing hope it helps you out.
