Just bought an original MkII GT - Page 3

I think Steve will be much more comfortable in his new GT. It is a shame about his CAV being stolen; Hope those bastards burn in hell.

Restored brake master cylinder back in the car, about to be hooked up and tested for leaks (ain't got no more leaks [img]/ubbthreads/images/graemlins/smile.gif[/img] )

Completed battery hold down. The lower blocks are 6061 aluminum & are helicoiled (actually I used Perma Coils). The top piece is magnesium, and seems to weigh about as much as a single of the lower blocks when you hold it in your hand. I don't have anything to weigh them for real.

Odyssey battery btw...

Someone was selling a front bumper on eBay, so I bought it. The new one even has the rubber bumpers...

I've been pretty busy so haven't had a chance to update this page lately. The car has been moved to a secret undisclosed location somewhere in the western United States, where I continue to work on it.

This shop has heat and room for all my tools so I can use my garage for its intended purpose again.

Engine bay as it looks now. I have actually started the car and run it for about 15 minutes. Haven't driven it yet, as the interior is still in need of a lot of work (like the seats are out of the car right now).

I got these Panasport wheels from Dave Bean. They were used and showing their age (clear coat peeling), so I had them refinished. Tires (185/70R13) are on order.

I decided not to try to save the old gas tank/sender when I found that a 12 gallon fuel cell is almost a perfect fit for the opening. Only had to nudge the corners of the opening ever so slightly to get it to fit.

Steve Toner · 12-10-05, 10:10 PM

I made a vent to fill the hole where the original filler cap was. Even though it's aluminum, it's kind of heavy for what it does. But it looks pretty cool.

Steve Toner · 12-10-05, 10:11 PM

Cover removed to show the nostrils. And I stuck some open cell foam in there as a filter.

Steve Toner · 12-10-05, 10:12 PM

Pulled a new aluminum fuel line. As you can see, the original clips are too small, so I had to make some new ones.

Steve Toner · 12-10-05, 10:15 PM

Detail of custom clip on milling machine.

The fuel pump needed a little work. The little check valves (I call them heart valves) were sticking & preventing it from operating properly.

Steve,
Just my 2 cents worth, but aluminum tubing should not be used for fuel lines because it will work harden over time and rupture.

[img]/ubbthreads/images/graemlins/confused.gif[/img] I've heard this about copper brake lines, but where does the work hardening come in in this application? It's not under any substantial pressure, and is rigidly attached. There's a braided flex hose for the last foot or so between the filter and the fuel pump.

It's used in planes, in race cars - I don't think there is a problem here.

PATGT40 · 12-14-05, 10:38 AM

I am going by memory here, but it seems to me that when I installed a Holley projection system a few years back that the instructions were very specific about using steel tubing and not to use aluminum tubing. Cars vibrate and things move around, including fuel lines. The aluminum is soft and can easily wear through over time if it rubs against something. Use steel brake line tubing and flare connections. When you add hose at the ends the tube needs a rolled bead so the hose and clamp cannot slip off.

Steve Toner · 12-14-05, 12:47 PM

Hmmm. I'm not familiar with that Holley system, but if it is injected (and from the name, it sounds like it might be), I could see that there could be a problem because of the higher pressures. And if the pump is in the tank, I could see a problem. I think the failure modes in my system are not so bad, assuming the line were to fail. Since the pump is on the engine, a broken line would be like drinking through a straw with a hole in it, and the engine would likely just die. If the hole was below the tank, it would leak gasoline but wouldn't spew it because there is no pump pushing it from the tank. A leak above the fuel tank really wouldn't leak at all I don't think - the fuel in the line should just drain back into the tank.

btw, all of the connections are AN- fittings. No clamps. Body flex would seem to be the only thing that would put stress on the tubing. Plus, the line is plenty cheap and easy to route, so can be changed every two years or so whether it needs it or not just to be safe. I don't think there's a problem...

Corrosion is also an issue. It's your car and just my opinion. Anyway, good luck on the build!
