5-0 Blackbird

I was just looking around for ways to run the fuel lines on my Firebird because I am thinking about an LT1 swap, but the car was carbed. So I'm gonna rerun new lines, but I have no idea what type of line to use. I did run by these Twist Tite hoses by Summit and was wondering if anyone's used em? Anyone have an opinion or experience as to how'd they do working as fuel lines in a fuel injected car? I see they're rated for 250 psi and would seem to be easier to run. Just thought I'd ask before jumping on em. My other route would be with braided hose, but it seems really expensive and I've never used em before. Thanks for any help/ opinions!!

I use them in my Z28.i used aeroquip hose,instead of the twist tite hose.as there was a three week wait on the summit brand,and the aeroquip is the same thing.i used it with the twist tite fittings,and it works ok in the engine bay,no leaks or anything,and it is reasonably flexible to work with.Are you running new lines from the tank?,as I dont know how it would hold up under the car,without some other protection.Also if you run your car on the strip,there is a limit on how much rubber hose you can have.

If you're replacing from the gas tank to the engine bay, you should keep it stock(OEM) metal lines. Inside the bay, braided lines look great! But unless you drag race your car?, or it's a show car?, the lines AND the fittings for braided lines are VERY expensive! Under the hood, rubber is good enough!!!!

Braided Lines can also be a pain in the A** if you've never used them before!

Ya, I figured there would probably be a prob with running them the whole way. I am running all new lines from the pump up to the rail. And as far as the track goes, I only go like 2-3 times a year and it's not gonna be a show car. For the OEM metal lines, is there somewhere you can order those? I only ask because I can't find anything searching local auto parts stores sites, like advance, unless I'm searching wrong. Or do they have em and I just need to actually go there and mention em? Only fuel line i've bought before they either give ya rubber, or a length of metal line that you form to fit. All the ones in the yard are probably rotted. Does it matter if they're from a TBI compared to a TPI? Ya, no kidding on the braided lines, looked at em and they'd be cool, but can't really swing em right now, at least not to run the whole way. I have never used em before either, and as you said, from what I've seen they look like a pain.

Well the braided lines them selfs aren't the problem, its the attaching them to the new "braided line fittings", my buddy has them in his 91 Syclone. And I really don't trust web sites LOL.... I would just go into a GOOD parts store and ask them for Types(metal, rubber) and Fit(costum, or OEM) of fuel lines. TBI vs. TPI Sorry i don't know.

As an Aeroquip distributor, I recommend Aeroquip brand Racing hose. It's rated to 1000 PSI and 300 degrees and I personally run it on my Camaro. Be sure to have the fittings crimped on instead of reusable fittings or hose clamps. Much safer and less of a hassle in the long run.

Thanks for the help paulo, Ya, that's what I meant. I saw some instructions/ pictures somewhere online showing/ telling how to put em together and was like wow, lol. Well I was told in another thread to use TPI lines because they come up to the right spot. So looks like I'll just find a set of those. Thanks for the recommendation Jr. Mechanic. I'll have to take a look at em.

I grabbed a set of the nylon fuel lines that are on 4th gens. $10 total from the JY.

Lol, will do. I'm trying to decide what LT1 to use now, there's two at the local yard, but idk which one to spring for. I guess one runs and is a 94' caprice wagon (127,XXX miles), but needs fuses and the other they couldn't get running, which is in a 95' roadmaster (I figured probably opti as it looks spotless and has 109,XXX on the clock). I just picked up a T-56 the other day so that's all set besides a clutch kit, flywheel and pedals. I did run into some luck as far as the fuel lines though. A friend of mine is parting/ junking her 91 or 92 B4C police camaro (had the L98 of course) and told me to let her know what I need. So I'm just gonna grab the whole tank (if it's in good shape) with everything still in it, the fuel lines, the aluminum driveshaft, and the posi disc brake rear. So after all that and an engine, I'll just need the wiring, fuel line adapters, little lengths of braided probably and exhaust (can't decide to go cat-back or true duals). That's cool Rich, I'll have to go check my local yard again, but there's only three 4th gens and they're all sixes, and they probably have different fuel line hook ups huh? Thanks again for the help guys!

Actually, the lines I picked up from the JY are from a V6 4th gen and they connect to the V8 LT1 fuel rail. I just need to connect the nylon to the metal line using a fuel line union/connector.
