Seems lately that I only work on "others" cars Marty.


Did a quickie fuel tank extension project for my brother in laws Camaro last weekend -- and made him a different fuel line...

I didn't have time to build him a whole new tank from scratch -- so he'll just have to wait til the new shed is set up this winter. In the meantime - he can cruise this summer without being so worried about where the next gas station is.





That POR 15 is tough stuff!!!!

Needed to open up the bottom anyway - so cut out the old fuel pick up tubes

Punched it with some new holes....

The tank was so warped there was not a single "square" or flat panel on it.... UGH --- What a lot of work to try to get the new extended area to at least appear to be flat and straight!

STUPID TANK!! Wouldn't stand on it's own..... SO a few clamps and some legs and now I could do a little TIG work.

I had nowhere for my hands to rest --- so had to bend up the torch and weld running the bead towards me.... OH MY -- this is easy for the girls that do welding day in and day out -- but for those of us that weld sporadically -- it's work!

26 sticks of fill later....... Thank god for TIG FINGERS!!! They really do help with the heat!

I have no clue how you can weld an old gas tank. It has always scares the heck out of me. We had a kid at a local repair
shop die last summer when he tried to fix a leaky tank. It exploded and fortunately it killed him immediately and he didn't suffer.


ps I will be bringing my car over soon

He - unfortunately is up for The Darwin Award....



Welding on gas tanks is super easy --- and I don't do ANYTHING that isn't safe!



First you have to wash them real well with a strong mix of some kind of soap and water.... Gas is an OIL based product -- so you can't just rinse with water like some morons try to do.... I use Simple Green -- and it's a strong solution. TWICE.

Then I use the SNIFF TEST.... Still smell gassy? Wash it again!


Then I rinse two or three times - until there's no soapy water....


Then -- Here's the trick! I put DRY ICE in the tank -- as it dissolves -- it turns into an inert gas -- Carbon Dioxide (CO2).... NO OXYGEN - NO IGNITION. It's the FUMES that kill ya! (Gas fumes and air). I displace all the air in the tank with the CO2.

I'd use a back gas of Argon... but that's expensive for a "home guy".... as you'd have to displace the air in a pretty large space. I can do this cheaply ---- AND I CAN SEE IT WORKING --- when I use Dry Ice.

That is a great way of doing it. When I convert to efi I will bring you the tank

Well - Thanks to DBasher.... I have a new race item that will officially make the Little Mustang way faster than Gaetano's Cheby....




That steering wheel HOOK == Now that's an official RACE CAR ITEM!!! Thanks Dan!

:thumbsup:
It only took a few hours after work to make, hope it fits well....haha!

Oh and Happy Birthday!

Yeeeeehaaaaw!

:D

Nice add Greg. I put my helmet on the passenger seat and then my steering wheel on top of my helmet. Gives me that unorganized feeling. I need one of those. :thumbsup:

So, why would that Vette you were looking at pass sound (or would it?) and not the Lotus? me no understandee.
Not to mention some of the NASCAR's up there racing, am i missing something from the Lotus or do they just not like it up there?

That ain't all you're missing dude.....



They love the Lotus. Just not when you aim the exhaust at the meter. And no the Vette wouldn't make sound.

My two cents, not that anyone asked...

The screwed up thing about Laguna is that while there is a sound limit, you can PAY for a loud day and gain a few more decibels. Apparently the locals care about noise levels, but if you're willing to pay to inconvenience their ears, well that's okay.

All of my experience on track is with bikes, but I have several hundred laps around Laguna on probably a dozen different bikes. The only bike I haven't blown sound on was a KLR650 that I brought for putting around town. The weather plays a big part. I have known people with bone stock 600s to blow the sound meter; it's the airbox noise. But a few times I have gone by on my race bike at full tilt and it wouldn't be a problem.

I'm betting the sound meter is the reason that they set up a slalom section between 5 and 6 for the USCA event. Low RPM is low(er) noise. Kinda ingenious in my opinion.
