New Fuel Tank Design

[hossbronco]

Thanks, Todd! That’s some helpful information I’ll keep in mind.

Don't know if this has been mentioned yet, but is there a tank that can read the correct fuel level? I've got one of the monster 23 gal. tanks in my rig, everything is brand new and the reading is totally screwed up, therefore, I never really know how much gas I have left.ugh.

I'm sure this Lick Creek/Duff tank reads correctly - they spent a ton of time getting that right and using the ISSPRO sender. My M1A1 tank also reads very accurately (for a Bronco tank) as I noted above. I don't know what brand your 'monster' tank is.

I've had three different tanks over the years: the NWMP (Sunset Fab) tank, the BC Broncos (aka WH Sherman) tank and the M1A1.

The NWMP and BC tanks were pretty similar, in my opinion. I tweaked the sending units on each as best I could but the lack of accuracy on the gas gauges always kinda bugged me. It's been a long time since I had the NWMP tank but I remember it took several fuel filters to get all the welding crud/FOD out of the tank. I used it with both carb'd and EFI setups. I recall 1-2 instances where the fuel pump lost its prime on steep climbs with very little fuel left in the tank. The BC tank was a little easier to install. Mine was an earlier version without the -6 fittings on it - I always wanted that feature. Fabbed a great stainless pickup line in it with Lars' help, mimicking an aircraft setup and that tank would run until it had 0.5-1 gallon of fuel left in it.

The M1A1 is the nicest of the three and the ISSPRO sender is awesome - my gauge is more accurate now than it's ever been. The Walbro pump is noisy (this is my first experience with an in-tank pump after 23 years with an external pump and no issues). I'll eventually tear it out again and try to quiet it down. The cork gasket supplied with the pump module was missing half its holes so I had to punch those prior to install. I eventually changed the cork gasket to a rubber one from Tanks Inc. I also had sealing issues with something around the top of the pump module - I think it was the electrical connections. Again, a healthy dose of aircraft tank sealant from Lars helped solve that issue. I bought the optional skid plate and I like it along with the J-hooks. I also added pump module flange screws with the o-rings on them for better sealing.

I also considered the Kincer tank - beautifully constructed but hangs waaaayyyy too far down for my tastes. I also don't like that it (and the Duff tank) insist on using the Aeromotive 340 lph pumps. They're good pumps but they require an additional fuel pump relay installation due to their current draw. Very, very, very few EB owners would ever need such a high capacity pump.

Just some of my opinions from many years of usage and a lot of research into the various tanks. I think the Duff/LCR tank looks like a good one.

Todd,

any chance you can send me a link to that aircraft tank sealant? i tried to weld a bung on my stock tank and yup its got plenty of pin holes. i got some JB on it now and its held up so far - the air craft stuff is probably better.

thanks

Here's a pic of the tube I had.

When I sealed the baffles in my airplane tank (15 years ago), I used CS3204 sealant as recommended by a military mech.
I purchased the goo through this company.

Any real-world reviews of this tank to share? I have a hole burning in my pocket.

Fuel leaks My experience

For a gasket whether a leaker or for a potential leak. 1/16" Buna-N (Nitrile) sheet and make a new gasket. Yamaha sells a sealant product that works with our gas. Be sure and search because Yamabond sells several versions. The one I use set up semi hard and worked such that I could no longer detect any odor. I cannot find the part number after all these years. There are choices. I remember I just went to the Yamaha dealer and ask the counter guy for fuel sealant. Now days all the motorcycle companies sell a product that have identical results.

The use of http://flamemaster.com/

cs3204 B2 sounds like a good product.


For my auto trans pan I welded a bung, and my weld had tiny porosity. I discussed the situation with an engineer at JBWeld and he told me that all JBweld products are indefinitely compatible with fuel, ATF, and motor oil. I cleaned up my weld with Acetone and cooked it with my propane torch and coated the weld. The result after many years was successful and I never saw any ATF dampness around the Bung.

JBWeld comes in different temperature applications and lately I have been using the high temp stuff to bond a fitting on the roof of the Jeep which get very hot. That is the stuff I would try on the motor oil pan if I had a leak.



Having said the above if I had a fuel leaking, I would just use 6 minute JBWeld for leaky pinholes or for gaskets. I trust the JBWeld engineer.

Here is a discussion for Yamabond and comparable products.

Here's a little comedy for you. Also - we unbox the tank let us know if you have any questions.

And great looking tank brother.. thanks for sharing

Nicely done, the bronco gods thank you

looking forward to the install video. please include 77 tips in it since it sounds like i'll need to drill more holes.

We have the install video slated and will be showing all of the differences. There is a template provided in the instructions for this. It really doesn't change the overall difficulty much, mostly just adds a few more minutes of time.

It would be neat to have just a 77 model, since it's different. I personally did that on my stainless fuel tank I fabbed. So far I have had zero issues with mine, which is pretty darn cool, since it was the first I ever made.

 

[englewoodcowboy]

It just doesn't make manufacturing sense to make a different mounting plate to fit the 77. The cost of this was already a lot more than expected to make so having to make additional brackets etc for a 1 year only, I think too many would just simply opt to drill the additional 2 holes.

The 77 mount is just so cool. But I can see your point, I actually think it would be better to only sell 77 style, then have people install nutzerts into their frames.
