Hi guys, I'm new to the site and i've got a fuel line question.

I've got a 91 RS, I'm the second owner, and the lady who owned it before me lived in IL. and aparently didn't park the car in the winter. So now, there is alot of rust on the fuel lines, along with other things, and it's sprung a leak. The lines running from the front to about midway under the car are in good shape, but from there back they geat REALLY bad. I was wondering if I should just cut the lines and buy some 5/16 rubber hose and slap that on there OR should I get all new metal lines (thinging aircraft grade metal)?

Any imput would be appreciated, thanks in advance.

 

Metal

 

Another thing. I'm about to start a build-up and rebuild on my motor. I'm looking ar getting the holley 670CFM TBI unit, but it's not listed to work on my car.

Whats the difference? Why won't it work? Someone told me the TPS has a different plug or something to that affect.

Is this true?

Thanks.

 

like AJ_92RS said, go with metal lines.
the TBI section of the site would be a great place to find out what the deal is with the holley 670CFM TBI unit.

if you dont mind my asking what happened to the original wheels for your car?
from what I know all 91-92 3rd gens have the wheels like what are on my car.(pic in sig)

 

here is a better pic of what wheels should be on your car.
if you didnt change them id personaly wonder why they were changed.

and sorry for the OT

 

The Z28 wheels where optional on our cars.

The nice thing about it though (a little known fact) is that if you ordered the 16" wheel package, you automatically got the Z28 suspension.

 

sorry for the screw up! my bad I thought all 91-92 had those wheels.
kinda cool finding out I got the Z28 suspension thoe.
ya learn some thing new every day.

 

I wish the person who origionally bought mine would have sprung for the 16" Z28 wheel option. But, oh well

 

why not replace the lines with nylon? When I worked at a bus garage thats what ALL fuel lines and also air lines were. Not only do they not rust or rot with water, but the only way for them to spring a leak is if they are burned or scraped on a sharp edge. If my camaro was drove in the winter i would replace it with them and I have a winter beater that the fuel lines went out and I replaced them with nylon, only 1 winter on her but no problems.

 

Can I get Nylon line at any local parts store like Autozone, ect..?

 

I always got it from the shop I worked at, but if there is a local junkyard with buses you can snip whatever from the air lines. However I don't see why autozone wouldn't sell them, they are not special made or anything fancy. you will need the compression fittings and ends to secure a tight fit but all n all, you won't have to replace it ever if you run the lines correct. Also I seen nylon lines at a hardware store. Make some calls

 

Buses don't sit 5-6 inches off the ground. If you run over a pop can in a buss, it gets smashed.

If you run over a pop can in an F-body, it can fly up and hit the fuel line, cut it, cause a spark, and then FIRE!!!!!

No "flame" intended. Hard lines are just safer.

 

makes sense, but i'll stick with my nylon lines ran in safe places =]

 

Not to mention what would happen if it got a liitle too close to the exhaust pipe. Nylon tubing for fuel is illegal for state inspection in my state for these very reasons. Use steel brake line.

 

uuh, plastic line is stock on alot of new cars.. esp ford... ford seems to love the stuff.


so you guys are saying that my 91 RS has the same swaybars as the 91 Z28??




anyhoo about the plastic lines... its a ok replacement. but use FUEL LINE... not air hose line...


if i could afford it, i personally would just replace the hardline with a nice prebent hard line.... costs a lil more, but much simpiler..


other options include:
patching the line by cutting out the bad part and joining the lines

replace and bend the entire line..


as far as the TBI thing, im not positive, but i think the plug is for the TPS or somthing..... ask on the TBI board, or do a search there to be sure.

my personal opinion is that its a waste of money... swap over to TPI and get a stealthram, or miniram, or superram, or any other FI intake...

 

Not trying to be an a$$ or anything, but the lines on buses that are for fuel are ran close enough on the exhaust that if it would burn due to its weakness, it would. Most on a chevy 8.2 disel or the 6.9 as its close and them come factory like that, but be safe, no harm done when your giving your car as safe as possible items and treating her to a LIL tlc on the long/short run.

and also a pop can hitting a fuel line that is nylon n tearing it is a lil vlown out of proportion i think, I torched close to them and the body clamps fall on the them n push them against the frame and nothing happens. If ran in safe places, I think they are safe and i wouldn't have suggested it if i didn't see it with my own eyes.


anyway, if you are afraid, use steel!

 

Afraid......smart....... call it what you want.

 

once more i'll say:


nylon fuel lines are OE on most new cars.




use a fuel line, not a bus air brake line.





all fuel lines, regardless of what they made of should be away from the exhaust, and placed where they cant be crushed or easily hit by road debris.





its not really a point worth arguing.
