Need Tips: Replacing all rubber hoses, fuel line, coolant hoses under hood...
Hey guys, I have a BAD job ahead of me. Not too long ago, I had to replace some heater core hoses under the hood that weren't so hard to reach. Now A few weeks ago, a rubber fuel line opened up in an impossible to reach, hardly possible to even see area right under the AC...
The hoses aren't that old, but the engine was rebuilt before I purchased the car and the retard who did the re-installation under the hood, clearly replaced the hosing with cheap deteriorating crap. Present clamps are those cheap screw driver type hoses that eat up the rubber... and the worst is that most of the hoses, including the fuel line that opened up, are either rubbing against each or against some other random component.
So... A) can someone tell me, what is the most durable hosing and best clamps i can buy for this summer car?
B) Looks like I have A LOT to take apart to get to these hoses. Anyone who has ever done this job have some nice available tips?
Thanks.

What year is the car? I would guess an early C4 based on the fuel line being under the AC compressor.
You might have to take the AC compressor out of its bracket. The metal fuel lines that go up to the fuel rail go through the bracket.
I would go with the GM parts (if you can get them), but that's me. The fuel pressure is fairly low so you might be OK fabricating your own setup.

If it's the "T" that runs to the oil cooler (assuming you even have one on your 86), that piece seemed impossible to locate. And, yes, it's hard to get to. Maybe that's why it was reused...or even skipped. IIRC, it went from one size to another. I spent a lot of time just trying to find something for that job.
I don't think the hose type is a big deal, but you might have to ask to go to the hose aisle and get creative.
I have no problem with the normal spiraling screw-type hose clamp most often sold in your local auto-parts stores. Must better than those weird OEM clamps that were invented by the 70-80's pot-smokers at GM.

I was also thinking braided steel hoses. Since i'll be doing a tough job, might as well make it durable. My car is a laster. I'm not very experienced with these vettes, so wasn't sure if someone has been a bit more creative or knows of a longer lasting product.

To the OP, from your description it sounds like someone used regular fuel hose and worm clamps. This would be ok for your lawn mower but is downright dangerous on a fuel injected car - as you have experienced first hand. If you can find the oem stuff it'd be the easiest route, safe and correct fit. But we know with our aging C4s oem isn't always possible. Bottom line is to make sure to use fuel injection hose and clamps.

I would think you could source silicon "fuel injection" rated hose in the vicinity, Parker has E85 specific product I believe. There should be Parker jobbers in the vicinity, for clamps where needed I like Isuzu truck miniature clamps, a little steep on the price but they're constant torque, compact and professional in appearance.
Here's a couple GM numbers that a dealer who does truck service should have on the shelf to check out the construction, 97326928 and 97326927 - an Isuzu dealer can convert those numbers to theirs also. The Isuzu product is diameter specific and before ordering you should have your hoses in hand. If you liked the Isuzu style clamp you could order the correct sizes for all of your needs. You need a parts guy with some patience.
For steel fuel lines the Saginaw sealing ring flare can be duplicated in 5/16 and 3/8 with flaring tools that are available. Smaller could be a nuisance.

Nothing I said relates to fuel lines!

If I were tearing into that job I would invest in the proper fittings and braided hose. They are easy to work with, look great, and won't leak or deteriorate as quickly. Just my .02.
