Never got clarification about what year K5 Blazer to pull fuel lines from, so after looking at new lines for various 80s and 90s model GM vehicles, I went to the salvage and started checking mid-90s GM pickups. Sure enough, they have steel fuel lines of varying lengths.
This was an extended cab.





There are two sets on either side of the fuel filter, so I grabbed both. One set was about 4’ long, which would be too long, so I found a single cab pickup and the longer set was about 3’, which I thought would be perfect.

I figured these lines would have the right fittings on BOTH ends: the raised shoulder on one end to attach to the Quad and the threaded fitting on the other to attach to the Fiero. I was right, but there’s a problem with the 3/8” lines I’ll get to in a minute.





These actually have two shoulders, but that doesn’t matter.



The four lines cost me $18, and who doesn’t like the threat of old gas dripping on you while you work?

The threaded fittings fit the Fiero.



If I could bend it without kinking it, the 5/16” return line would not even have to be cut in order to fit. It’s because it attaches to the fuel rail with a flange that slides around it.



The feed line, though, is attached to the rail with a big nut, so that means the line has to be cut.



If I’m going to have to cut one line, I may as well cut both so they’re consistent. That means I can use the GTZ’s original return line because it’s long enough and only requires a little re-bending to fit the Fiero.

Looks like I’ll have to make another trip to the salvage to get some more 3/8” lines.

Still wrestling with the fuel lines, but here’s a cool story.

A co-worker who’s significantly younger than me texted me while he was on vacation last week to ask if I was interested in four speakers for my Fiero. Of course I said yes.

His first car was an ‘87 Fiero that he got when he was in college 12 or 13 years ago. The car had several problems and he never got to drive it regularly or make the improvements he was hoping to complete. After it sat at a shop for a few months he finally sold it and bought an ‘86 Corvette which he still has.

When he was home last week his dad had been cleaning out the garage and handed him these two boxes. He’d bought them for his Fiero and forgotten all about them. He said he was just going to toss them because he knew they were Fiero-specific, then remembered me. I told him I’d be honored to take them.

I don’t know if they’re any good, but I think the speakers in my car are the factory originals so in the very least they’re 20+ years younger.

Finally finished the rough draft of the fuel lines.



I followed the same process Sardonyx247 did, which was to straighten out the return line and reroute it from under the fuel rail to straight out the front of the engine over the alternator.



That frees up the space under the fuel rail and injectors for the feed line. I made a 180-degree bend at the end, then a 90 so it paralleled the return line over the alternator.





In this process I realized my eBay tubing bender is just too big, so I bought a $10 Harbor Freight version, practiced on several scrap pieces of tubing, then tried the real deal.



The stuff I bent looks pretty good but has some dimples from where I straightened the factory bends. I may swing by the salvage this week and grab another Silverado/Sierra fuel line to give it another try. After doing more Googling I think the 2003-2005 trucks have lines with only the single shoulder on one end. Not sure it matters because this one seems to be seated well.

Finally got the fuel lines sorted out. I did end up going back to the salvage and getting lines from a 2005 Silverado. Both the feed and purge lines are 3/8” on those trucks. One end has the quick connect flexible hose and the other has the bonded flexible hose, so you don’t even need wrenches to remove them, just some cutters and a screw driver to pop them out of the plastic clips on the frame rail.

I put the engine back in the car to make sure I got the lines just right. The lines on the engine were way too long.



Needed an angle in order to get the Fiero’s flexible lines to meet the engine’s steel lines without kinking.



The ends with the fittings came from the lines from the late-90s Silverado I got on the previous salvage yard trip. I thought a 45-degree angle would work, but it ended up being 90.



Looks a little kinky but I think it will work.

I cut the engine lines so that the compression fittings would be staggered, but after I got everything hooked up both lines fit better with their positions swapped. Unfortunately that means the fittings are closer to each other.

This means it’s just about time to start working on the wiring harness.





Can’t remember if I’ve ever posted about these battery cables. They’re from late-90s Buick Rivieras. Should be perfect for the Fiero because those Rivieras had the battery under the back seat, so the cables are about 16’ long.

The battery terminals are corroded on these, but the other ends have the eyelet for a junction box and the starter.







Probably ought to rebuild the rear suspension and figure out the clutch slave cylinder connection to the car’s system. Also need a new clutch master cylinder. And the throttle cable bracket, while the engine is in the car.

This is the first time I’ve had the engine in the car with the firewall heat shield installed, at least in a long time. It’s in the way. Since the Quad’s exhaust is on the other side of the engine, I don’t need this heat shield anymore, right?



It’s in the way of the shift select cable and conflicts with the throttle body.

I fabricated a throttle cable bracket today. On the Quad’s bracket, the throttle cable mount is about 1 1/4” too close to the butterfly.



Using the Quad’s bracket as a pattern, I made the new one in two pieces.



Ignore the welds. I’ll smooth them down before I paint the bracket black.



This is what it looked like after a dozen or so pushes of the gas pedal, all the way to the floor.



I would’ve ground down the welds and painted the bracket today but Oklahoma is dealing with the big dose of global warming hitting half the country so the shop was really cold. Hopefully more progress tomorrow.
