Jim, will you look inside that tank and verify that it's baffled?

thx, Steve

Hi guys, I'm back.

Looking inside the tank, there are NO baffles. It's just a big metal balloon. I would think that baffling would be a necessity on such a large tank, though it does have some deep ribs stamped into it for srength.

I'm baffled by the lack of baffling.:rolleyes:

Any updates Jim????
The fuel sender arrived the other day. It is a sender/pickup for 64-68 mustang. All I really wanted was the plate that pops into the tank to seal the hole. The 'stang part was the cheapest one on the 'net. It gives us the raw material to add the Cruiser fuel return line to, and something to swap the Cruiser sender onto.

Pics to come.

FWIW, the GM P30 van tank is also unbaffled, and I'll bet the Suburban tank is also.

Jim, once this thing is installed and functional, it'll be interesting to see how it does off-camber.

havnt thought about it much but I have one laying around. useing the 80 series tank as a second tank since it is mounted else where from the 6x series tanks. would prob have to re-route exhaust to do it though, just a thought though...
 
They've been selling these 33, 38 & 40 gal tanks in 'merikan trucks for years. None are baffled. Baffling would be nice, but the lack of it is not a deal-killer for me.

So I am putting this new fuel tank in my FJ60, in place of a perfectly good looking stock tank.
My F350 sees this and is now piddling diesel fuel out of BOTH tanks. It's a wheeled EPA SuperFund site. :mad:

G_dda$^%&*#it, more stuff that needs fixing.

Hey, what about a swinging (AKA Klunk) pickup?
Like on aircraft or chainsaws or jet-skis? That's a brass weight on the end of a rubber hose inside the tank. Wherever the fuel goes, the klunk follows along and so is able to pick up fuel most of the time.

Does anyone know of a 3/8"I.D. flexible fuel hose that will stay flexible for years, while immersed in gasoline?

Post it up a description and vendor, if you know of a source.
 
please excuse me if this is a dumb point. I d on't pretend to know a lot about these things.

I thought that we wanted these long range tanks, so we didn't have to fill up so often when driving to say, Moab. well, if I am driving at 65mph on the highway to Moab, with a half tank of gas, and I have to swerve to avoid a tire in the highway, will those 19 gallons in that caverness tank shift enough to risk fishtailing or be at risk of losing control of my truck? I thought that baffling was there for those reasons. I would imagine that a F350 Dualie, wouldn't have to worry about that as much as a lifted FJ60, with tall sidewall tires...... but if Baffling is not there for those reasons, but rather, just to insure good fuel pickup by the sender, then I could more easily live with that. Safety rules and performance come in second, in my book.

Chris, that is a good point. It has been mentioned earlier in this thread. For now, I'll install the tank and see how the truck handles, with a full 38 gallons in the back (appx 280 lbs of fuel), and also see how it handles cornering and on bumpy roads w/ a half full tank.
 
oh, good, glad you are going to do that Jim. I just wonder if you will be able to really test it good enough without putting on those anti roll bars with the little wheels on the ends to prevent roll overs like the government and Consumer Reports uses.

I am surprised that the aftermarket tanks don't have baffling. I know that this project is supposed to save us money. But at what risk.

the tank we are trying to avoid paying for, like at Man-A-Fre, for over $700, does have baffling:

since i sent my $10 smackers i figure to add to the discusstion.
i just sent my fj45lv fuel tank to get cleaned and coated to these guys
http://www.gas-tank.com/
while i was on the phone with him just now i figured I would ask what it would cost to add baffles to a tank. he said whether you supply the tank or he gets it (ie aftermarket ford tank or what ever we decide on) he can add baffles and coat the inside and do hs magic to the outside as well for $150. he prolly can get the tank cheaper than one of us could as well so the cost from him might not be a complete $150 more but who knows.
i don't know what this does to the final cost of things but it is an option

1) find "12-951 " on this page: http://www.autoperformanceengineering.com/html/ext_pump.html , or navigate to Fuel Pumps, External on the left menu bar and scroll down the page.

here's a page where somebody used them:

interesting fj6202840, and thanks. I wonder how they would add the baffles? open it up? take it apart at the seams? I think that is a good solution just to buy the new tank from them (the one Jim is using) and have them put in the baffles and coating. I sure would feel better about it.

uh, I am not over it, srplus. it is still an important issue to me. atleast untill convinced otherwise. just curious, why it is that you hope "we" are over it? my concerns are my concerns, and shouldn't affect you. If jim can come up with a solution that I can opt to have baffled, then I will probably choose to go that route.

I think you missed the pun, dude.
 
Easy way to solve the baffiling problem is to fill the tank with closed cell foam. Just like they do with fuel cells. It only takes up about 10% of the space of the tank. Therefore a 38 gal tank would hold about 34 gallons. It works really well and will elimante any slosh effect. It also is very inexpensive. A company like Jazz or Fuel safe has it in stock. The real work would be stuffing it through the sender hole.
