Massive Fuel Leak Need Help / Fuel Line Question 98 V70

[98V70T5]

Update...

I determined the hose in question is the return line. I also determined what I suspected is not a hole either. The rubber looks like it has been chewed away, and the black shiny appearance is actually the hard nylon line which I confirmed. The actual leak is on the opposite side of this suspected hole.

I made a video of the fuel spraying out from that area of the hose. I will try to find a free site to host the video. My best guess is during the two weeks the car sat, something must have chewed into the line because the car was driving perfectly prior to this.

How would you repair this? Does the tank need to be dropped to run a new factory line? Can a splice be made? What size diameter is the return line?

I have included some pictures from the video. You can see the amount of gasoline being leaked highlighted below. Car is undriveable. If you look at the one picture does that look like bite marks to you? That is not a picture of the leak though. The hole is on the other side, and I didn't get a picture of it due to exposure issues with the camera. Will try tomorrow.

Thanks

Found a host, here's the video. I cycled the key briefly, twice:

It’s a spongy rubber sheath with a hard nylon? line inside which carries the pressure.

There are brass barb repair kits where you heat the nylon with a hair dryer (no flames please) push the barb in, and oetiker clamp the joints. Details in this thread, I used the repair kit to go onto the rollover valve barb, you need a brass barb to bridge the critter hole.

I had the same problem Steve had on my T5 auction car, it had tooth scrapes which I scientifically determined were squirrel (not really, I just guessed.) I used the Dorman barbs too, cut back the rubber chafe guard far enough to get a good grip on the hard plastic line. Hair dryer/heat gun works to make that line slightly more cooperative if used carefully. You may need to trim a small amount of material to make room for the center part of the barb, and it pays to treat all those line gingerly, because Old Age.

What size diameter is the return line? 8mm / 5/16 or 10mm / 3/8?

Thanks!

I found a mobile mechanic to come. Which kit should I buy? I don't know the size of the return line

Can 3/8" Oiteker clamps be used on 5/16"? Local store only stocks that size.

My fuel line was only invaded at one point of entry, so I only bought the barbs. It's been too long ago , I'll try to dig around and see if I can find the package, but 5/16 sticks in my head.

If timing will work put Vernier caliper on hardline , after trimming the soft part back, post it up here, and I’ll pop some oetikers that will work inthe “ post”

Just buy both to be sure. They're $6 each, and you should be able to return the one you don't need.
