RickK's 170 rebuild

[RickK]

Nice work Rick!  

Keep in mind, your gas tank will have a chemical reaction when you fill it with gas and grow a bit. Space around the tank is needed.

Thanks.
I think they said 1/4".  I have plenty of room for that growth except on the very corners where it sits in the notch.  Hopefully they are stout enough to make it grow in other places  
I'll leave a little space in between the bulkheads and the tank for a little growth.

Chicken, eggs   .... Got it.. Both should be served fried the latter in bacon grease!!

Got a ?....on page 14, one of the pics shows 2 more half pipes under the tank, are yo still going to put them there and if so how would they drain if water gets to them, I was just looking quickly thru and saw your bulkheads, they look great by the way  and the fit is fantastic ....looks like you have a good plan, was just thinking with my fingers

[RickK]

The 2 other supports will be there but they are tank support only and shorter. I'm going to drill a hole and run a piece of PVC pipe for a limber hole in the rear bulkhead on either side of the long support to drain the tank area if for some reason water happens to get in there.

This thing is going to be a tank, that's like 8 layers of 1708

i smell a bigger motor in the future  

will be interesting to see how much she weighs when done compared to the original factory spec. nice work rick

Another option would be to drill weep holes on each side of the center PVC pipe at the back of the coffin.

Sounds like you have it figured out She's looking good

Another option would be to drill weep holes on each side of the center PVC pipe at the back of the coffin.

That would work as long as water doesn't work back into the cavity. Come to think about it I guess it could just as easy come back up through the limber holes.  
Might be the easiest way. Good thinking!!

And that's each side of each stringer at the bottom

Rick,

Your work is looking great.

I don't know if you have seen this before or if it affects anything you are doing, but I found this on the net.

    that seems like a lot    
ALL TANKS WILL EXPAND 2% IN ALL DIRECTIONS (LENGTH, WIDTH, AND HEIGHT) AFTER
EXPOSURE TO FUEL

Is that because of weight or chemical reaction/moisture? Both? I am no chemist(although I make a mean Black and Tan ), will it expand and then contract that much all the time? or just after initial fill, if it's just after fill I think I would be doing a test fill soon :)

[Blue Agave]

Rick, I agree with pzart.  A test fill would be in your best interest prior to putting a new floor in place.  Unless you are fabing a fuel cell door, replacing the tank would require cutting out the floor.

Edit: especially since you said the corners of the tank are touching the notches in the stringers.

I did a filled up test fit as well. Left and inch all the way around, and used 1" corecell cleats (2 on each corner) 5200'd to the stringers and bulkheads. Put them in dry first and filled the tank up to make sure there was no problems...

Thanks CLM, I emailed Inca at the very beginning of this and asked them for any installation instructions - never received a reply.  I wish I would have found this on their website.  I just went there and still can't find anything like this on the site http://www.incaproducts.com/site/default.aspx

The only place that I'm touching is the corners and really only 2 of them are snug.  Hadn't planned on neoprene at all.
Chris, did you drain it afterward to continue the work?
I guess I need to buy a lot of 5 gallon cans...

[gran398]

Guess in theory the corners could expand....but seems the expansion should occur in the areas of least resistance, that is, the centers of each run.
