98: Complete brake and fuel line kits

[WFOWS6IL]

Hey everyone, I bought a 98 Grand Prix SE 4-door 3.8L and need to replace all the fuel and brake lines. Is anyone aware of any complete kits? I couldn't find anything older than a 2005 and wanted to check in. I have the proper flaring tool for both fuel and brake lines, but if I can find pre-bent for a reasonable price I'd rather go that route.

Thanks in advance!

go on ebay and look for 25 foot rolls of nicopp tubing. its soft and easy to bend.

you cut out the part of old line you need to replace, pre bend the new line to the same shape as the old, flair its ends and install.

I wasn't aware they made that in fuel line, just brake line. I'll check though. I'm replacing all 7 lines (4 brake/3 fuel) as they are toast so I'm not messing with just replacing sections. My flaring tool will do the fuel line end for the quick connectors, but if I could find entire replacement fuel and brake lines that would be nice.

I found entire sets of fuel lines for 2005+ for 180 bucks and rather do that to save a little time. Too many other things I need to replace on the car so time is key. If anyone knows where to buy full lines for a 98 other than OEM, I'm interested!

fuel/brake lines, its the same thing.

you can get the new lines form the dealer, will cost you though. gm parts direct web site may have em. but wont be cheap either.

why the rolls of line are the best cheapest route to go. being you own a flair tool.

Ya, Advance Auto sells the Ni Cab lines or whatever they are called, but only goes to 3/16 so wasn't aware they made bigger. I've used that before with good experience.

GM wants over 300 bucks for the fuels lines so I'll bend them before paying that. Once I wrap up the upper intake up I'll start on that. Dorman intake I bought has a flaw. Gasket doesn't slip over intake ports closest to the TB well unless I push gasket to the side, which is odd. Also PCV valve retaining ring doesn't sit flush after spinning to secure with 1 side pushing 3/16 of an inch higher. Pretty disappointed with Dorman on that. Wanted to finish up my LIM and UIM yesterday.

this is a modded fuel rail i made the other day, thats 3/8 nicopp line. got a 60 inch length for like 20 bucks. i only needed 48 inches and wanted it fast, got it at autozone.

[SgtMarshal]

how did you attach the fittings?

[Scottydoggs]

compression fittings.

compression fittings.

I've never messed with compression fittings, does it take a special tool?

[Scottydoggs]

nope. two wrenches. hold the middle nut, then crank the two out side nuts tight.

[SgtMarshal]

I might have to do this because the modded fuel rail looks funny with the big gap it has.

[Scottydoggs]

wow, yeah that must stick up pretty far now for no reason lol

Go here to Classic Tube:

Complete pre-bent stainless brake line set for 97-01 Grand Prix for $239 + shipping

I used these guys and got a complete set of pre-bent stainless brake AND fuel lines for my '01 Suburban. Great quality and good price, highly recommend. My Sub has 2 fuel tanks, each with pump, evap, and return lines, so it cost me a bunch to replace all of those lines, but they were corroded pretty bad.

FYI, I see Scotty used compression fittings on the fuel rail, they are NOT allowed by DOT on brake lines....brake fittings must be flared.

NJ dont give a crap about them it seems. i got em on my brake lines too. i know of local shops that also use them on friends cars and trucks.

ive said it before, ill say it again, i never had one fail on me, been using them for all sorts of lines for over 20 years now easy.

[Burbman]

Have never used one on brakes but friends have with similar good results as yours. Just pointing out the "official" position since I don't know how picky they are in OP's home state of IL. Would hate to have him finish a repair job and fail inspection.

[Scottydoggs]

they dont really look at your car any more here, and even when they did, they never said nothing here. ( they were to busy failing you for a rust hole in the bumper lol) pass the braking test, and off you went. they drive the car over braking pads, so they can see all 4 working.

i know most states will frown upon them on brake lines tho.

Compression Fittings are awesome. Used one on a hydraulic clutch line on my Ford Ranger since had to cut the line to get out the slave. Never had issues with it.

[brettstoner]

Compression fittings are only rated for several hundred psi depending on line size. Your brake system can generate 1,000 to 2,000 psi during a full (hard) brake application. That is why they are outlawed on brake lines. They are not rated for the pressure even though many people improperly use them.

[SgtMarshal]

instead of using the compression fittings, can I just use rubber fuel line and a couple hose clamps?

[Scottydoggs]

you can, but thats "really not recommended"
