I have been searching high and low and I cannot feed and return fuel to/from the TB. Dealer has discontinued it, autozone/napa/etc dont carry it, LMC truck does not carry it, and I cannot find any TBI's in a junkyeard around me. Does anyone know where I can find these lines as I need them ASAP? Can I make them with AN fittings and SS lines? Its pricey, but I need these now. Thanks

If it helps, they will be the same as Suburbans from 87-91 also. The vans and pickups to 1995 might be the same too. There are tons of the subs in the pick a parts here, thought there might be out there too.

If all else fails. ClassicTube or Inline Tube can get you a set.

I just replaced those very same lines about three weeks ago on my '91 Burb, 350 TBI, 4x4. Got them from the local GM parts dealer. They were GM lines but a bit on the "long" side compared to the originals. Some hand forming to fit cured the problem. My lines had rubbed a hole in them both where they were braided steel over "rubber" . To cure that in the future I had to re-route some what and covered them with rubber hose zip tied around both.

I have called all the gm parts places around here and no one has them. I might as well build them, and since the summit store is 30 minutes away, its not that big a deal. However, I need to know the size of the line I should buy and what size fittings I should get to hook into the rear line as well as the TB unit. Thanks.

The lines are 3/8" supply and 5/16" return. The fittings are 16mm and 14mm respectively. As I said, Classic Tube are Inline Tube have them. I got a full set for my Jimmy about 4 months ago for about $250.

Well, I went ahead and rebuilt all new feed and return lines myself for about $50 from Summit. They look alot better and function alot better. Worth the afternoon it took as well as the $.

I Admire That!
