So this is a long story, and I'm going to try to make it short for you guys. I have a 1989 Delta88 Royale v6 3800. About 2 weeks ago I noticed a leak in my engine bay. Turns out it was a fuel line leaking. It was the back line that hooks into the top of the engine. Well, I thought I could just replace that line, so I went and bought a replacement at the GM dealer. Turns out, that shit was WAY rusted and corroded, so I really couldn't take it apart. So then I tried disconnecting it from the fuel filter, but that was a no-go because of rust also. Then I decided to drop the gas tank and try to disconnect the line directly from the tank. Turns out I can't do that either because of the smartass engineers at GM that decided to run the fuel lines directly into the fuel pump, smartasses.

So because of all these problems (the rust and everything else), I've decided to just take out the whole line, from front to back, and replace everything. So I need some specific diagrams or schematics or something for the fuel system and the brake system, because I'll also have to probably replace some brake lines due to corrosion and rust.

i wouldnt go the extreme of replacing the lines, the fuel filter thing is common even in 2000 cars. as for your leak where exactly was it leaking from? if i were you id take it ti the shop and have them install a new fittings for you. bring the fittings and line with you though so all you have to do is pay labor and the brake lines..go buy some rust converter or naval jelley from your local auto parts store, that should take car of the surface rust then just clean the area up and spray with rust proof primer.

So if the line is so corroded that the fitting won't turn, you don't need to replace the line?

If it's worth doing, its worth doing right. Saving money hardly ever saves you money, and rust converter doesn't make corroded metal come back.

If the car was 7 years old, it might be a point worth making, but it's 18 years old. Good luck finding a shop that will put new fittings on old lines.

This forum does not need your BS replies.

yes smart one cut it befor the fitting, double flare it and install new fitting.



oh really you have personal experience? i used it on 2 of my cars used the naval jelley, wiped that off sanded a little and sprayed rust proof primer,or rust converter. Rust cant spread if there is no oxygen able to get to it in case you didnt know.



it wouldnt matter andrew rust is rust rather 3yrs old or 40yrs old.



This coming from somebody who needs advice about engine mounts? your whole post dosent add much if anything to help. especially since you obviously have no experience with rust chems. and such, so how can you talk?....now lets begin another quote fest with you and your friends

The leak was where the metal part of the fuel line connects to the engine block and then transfers to rubber. The rubber part had a hole from I suspect heat wear and old age. My car is in such dismemberment at the moment that I couldn't take it to a shop without having to play for a flat-bed. Finally, the rust is so bad on some of these lines, especially this brake line in the back, that it really does need to be replaced now that I have seen it and have access to it. It would be stupid of me to just try a cosmetic fix on these lines, especially this brake line, being that it is a frickin brake line.

The damage is done. Naval jelly doesn't produce metal molecules.



Only to warn him your advice is stupid. It worked.



One only needs to know one thing about them- They don't make metal. What rust has eroded away, is gone, turned into oxidized flakes or powder. POR or any other rust converter, chemical, Naval Jelly, etc will not build up what metal is now gone.



The thread will be locked before that happens again. Consider that a final warning.

Good choice- Let us know how it turns out!

Fully agree with you s0ad and andrew....they may look good cosmetically after doing what 91parkave suggested, but structurally they are an accident waiting to happen...literally. Using naval jelly removes rust yes, rust that used to be metal...essentially hiding the weak spots.

My 87 delta was the same way...luckily the brake line blew in the driveway...it was rusting and it decided to burst in one spot on the passenger side brake line...due to the rust. I also ended up replacing the fuel lines because once I touched them to replace the fuel filter, they started leaking in various places--ended up using some sort of plastic tubing from NAPA, for fuel injection.
