I've done this on my '85 when the supercharger went on. You can replace all the lines with FI hose and FI clamps. Changing the front line is the same procedure as the rear U shaped one.

No, this one, and others I have seen, was fried inside and out. If you can snap it by bending it too far you probably shouldn't use it in the first place. And I would suspect any line with a cracked outer. Given how cheap this stuff is its a no-brainer to replace it if there is any indication at all it is at the end of its life. Modern FI line is very flexible, take a look at the Goodyear data sheets on theirs for example. And btw, your later post is right on, a complete fuel line replacement can be done with a trip to your favorite parts store for hose and clamps - that is, the right hose and the right clamps, as has been pointed out.

The difficulty is in selecting the right hose. The subtlty is pressure rating and bend radius. The hose in the kit is rated far higher than needed in pressure, but it gives the tightest bending radius, so its a good selection for our cars. The stuff I bought locally collapsed. I think the kit has a high pressure version of Weatherhead hose. My only complaint is the accompanying hose clamps have sharp edges near the screws I keep getting scratched on (not in contact with the hose of course).

Here are the two front ones on a '91 I'm doing today. Will post pictures of the rear hoses when I get back to them. This car has 123k on it. I think it was a previous R-listers car out of Ca that got a new home here in DFW last month.

As Andrew continues to point out you can buy the hose from any reputable auto store.
However be very careful to only buy EFI hose to SAE30R9 as ordinary fuel hose is not suitable at all in respect to working pressure and bend radius.
Also only use EFI clamps made specifically for this type of application.

Mine looks like it is smiling… I’m pretty sure I wouldn’t be smiling it this got too much bigger.






Roger’s kit is going on my car soon.

Your intake looks sweet Kurt! By the way I just posted my first thread...you wont believe it but my flex plate is cracked again.

Have not dug in to the '91 I started with earier, he's got a bunch more stuff so I'm doing an 87 tonight.

This picture is an Early '87 (8/86 build)

On the 85 to mid year '87, the hose that goes from the adapter that leads to the FPR, ending at the fuel cooler is a nice pain in the **** to do, seen quite a few that end up stripping the nut. There isn't much room to work in there and a proper pipe wrench sometimes will not work.

If it's being a pain, cut the hose and take a gear wrench (shorty) and loop it up on to the nut. Have an extra hand around to hold the 19 you will want to counter hold with, and have at it. Works like a charm. No chance of rounding the edges.

Landseer

Great idea. Out of the box. Thanks for that.

SeanR

Here's what the '88 and up looks like. This one is a '91

Also, great time to take care of that MAF harness that just happens to be crappy. This car has not been able to pass inspection and I think when you look at the 2nd pic, you will see why.

Sean - Do you use anything on the threads of the fittings--like a teflon tape or goop of some kind to prevent leaks?

Thanks / Bruce

SeanR

Nope, nothing on the threads. Some say to use anti-seize but I keep them dry. You don't want to use any tape due to it possibly getting in the lines and clogging stuff up.

Just finished mine tonight (rehydrateing now!!) on my '87 S4, followed the trend on this forum for peace of mind but I must add that the hoses were really well made and looked good, almost a shame to hack them apart, but 23 years is long enough I guess. Used aeroquip braided hose for the pressure lines and plain FI hose for the returns from FPR, a PITA to do but not as bad as the front upper conntrol arms! The front hose fitting on the fuel rain put up a hell of a fight!
Carpe diem.
