Greetings all,

Got so much done on this van “above ground”, and now I’m starting to work from the bottom. I got her up on a lift for the first time, and what I saw left me in awe of rust especially as it applies to the lines.

You might say, ok sure but which lines? My answer is unfortunately ALL of them. They all are crumbly rusty and scary. I’ll keep a long story short, and decided I’d like to try to replace the following:

All Fuel Lines
All Brake Lines
Trans Cooler lines
Fuel filter
Seals from back of engine through transmission. (Need help finding these)
Anything else that commonly fails in this region. (Help requested below)

I came up with a couple questions I can’t figure out even by googling within this site:

Regarding the fuel lines, I listings for both front and rear fuel line kits, but then rock auto only has a couple listings. I assume I need both these kits(6 lines total it seems), what is the difference? Do I?

For the trans cooler lines, any advice on what to buy?

I see what I would call a rear main seal leak too, and can’t find that part; ideas?

Maybe most importantly: I’m going to be doing ALL this work; what should I be sure to replace while I’m at it? I’d rather put money in now, than replace stuff one at a time as I hope to keep this van for many years.

Thanks all!

Im doing this right now with my fuel lines as well.
Id order a bag of brackets and clips for the various lines.

How is your fuel filter bracket? I have to replace that with the lines for mine

That’s a great point, thanks! I will probably try to find one, as everything there is rusty I’m in salt country.

Where did you buy your lines? Do we indeed need “front set” and “back set”? Is that 6 lines total? (As in, two sets of three lines basically?)

I have been assembling lines for a while from a shady looking online outfit called linestogo.com which turns out to be fairly legit.

I have bought over time the front and rear sets, as they are not cheap. I can say that they shipped fast and they looked good, but I haven't installed them yet, so not sure on fitment.

I got both front and back, but mine are all horrible. If you can get away with one set you will save a decent amount of money. The rear set (which I ordered most recently and am waiting for) appears to come with the fuel filter, but no bracketry.

You're definitely not alone!!

On my current 2002 AWD which had powdered line syndrome, I replaced all of the brake lines and fuel lines with braided stainless lines and AN fittings. Cost a little more, but much easier then trying to find the metal ones or bend new ones. Some are not even made any more.

Latest project last week was the rear heater lines. The metal pipe part of the assembly running along the subframe succumbed to the powdered line problem and had to replace them from the joints by the ABS unit back. The brine solution they are using on the roads here is destroying everything metal here.

Thanks so much for the info friends! Yes I saw this lines to go option. Glad they look good but yes it’ll be a $500 bill if I need to do both. But then again I saved $500 by doing straight pipe after someone was kind enough to relieve me of the catalytic converter.

Braided lines sounds tempting, but I can’t say I am knowledgeable on what to buy, etc. interesting!

I’m fine on brakes, I have the coated lines to use there “in stock”.

Wondering on the seals, then; if anyone had had those leaks.

Oh, and also the trans cooler lines it seems like the only part is like a $15 part on rock auto. Are those parts decent enough? Wasn’t seeing OEM options for that.

I went with the linestogo front and rear fuel lines on my 2000 awd and nicop for the brake lines. The linestogo lines are really well made but I did run into an issue that I need resolve at a later date. The braided lines that come with the set are really nice but the ends of them are rounded and wider than the lines. There is a spot under the van just passed the backside of the engine where all 3 hard lines fit parallel to each other in a plastic retainer. I couldn't get them to fit correctly because the rounded ends of the braided lines interfered with each other and spaced the hard lines out too far. I also ended up damaging the clips on one of the braided lines at the fuel pump because the color coding was off between the braided and hard lines and I had to remove them a couple of times. So I ended up just making new plastic ones with the dorman kit. They're expensive but if you want hard lines that are fitted to match the oem routing they are probably the best option.

Would you mind expanding on the amount of braided stuff you used ( instead of the solid 5/16" copper or that new copper/steel alloy ) ?
And what exactly is the AN series stuff ?

Any pics?
