Fuel tank question
Got a 1979 F100 Ranger Lariat. Want a bigger tank. Looking at this, and I think it should fit:
https://m.summitracing.com/parts/sgt-f26b
Summit thinks these are the straps. So how does it use the same straps for the smallet and larger tanks? Are these the right straps?
https://m.summitracing.com/parts/sgt-st16
Finally, since I pulled off all the smog controls, I no longer need the vent line from the tank to the front. Where can I get a tank without a vent line? I'll just get a vent cap.
Any help is very appreciated.

I dunno if that F26b tank fits your application, but in general it looks right. as to the straps I think the larger tank bulge down around the straps.
As to the vent line--- you need one to prevent vacuum build up in the tank. just run that hose to the breather body instead.

Work time for some part #'s...Looks like that one will work. Same lower straps either tank, just uses longer mounting bolts. All threads comes to mind.
"There are two differences between the tanks. Tanks with EEC have a hole in the top center of the tank. A rubber grommet and check valve are pressed into the hole. A line goes from the check valve along the inside of the passenger side frame rail to the engine compartment where it hooks up to a charcoal canister. Non-EEC tanks don't have this hole. The other difference is the nipple for the breather line that is located right next to the nipple for the filler hose is located 180 degrees opposite.
If you are going from an EEC tank to a non-EEC tank you must also change the fuel cap to a vented style. The EEC tanks are vented through the EEC system and use a sealed fuel cap. Non-EEC tanks vent through the fuel filler cap. If you run a non-EEC tank and a sealed cap the minimum is you'll have fuel starvation problems, at worst a collapsed fuel tank.
Is your truck a long bed 4WD? Does it have evaporative emission system? There are two possibilities with the plastic tank.
79 F150-350 regular cab, 133" WB 4WD, w/ evap. emissions system, 24.8 gallon mid-ship plastic tank D7TZ-9002-C
Same w/o evaporative emissions system 26.3 gallon plastic tank D7TZ-9002-D"
Do not forget to get a new sending unit for a larger tank.

If you go to a bigger tank you will have to extend a normal sending unit. Some supply what is needed for the fuel pick up, but I don't think any supply a way to extend the float so the gauge will read better. With all that being said, I have a 38 gallon tank in mine and I don't think I'll ever go back!

Hey PEB, I think if you want plastic you will have to go with the 33 gallon tank for the 78/79 Bronco. Here are a few links
Fuel Tanks-Broncograveyard.com
Plastic Gas Tanks :: Ford Plastic Gas Tanks
79 Ford Bronco Fuel Gas Tank 33 Gallon New | eBay
I looked for a few months for a plastic 38 gallon for a Dent and never found one. I have heard of people using the Bronco tank with out problems. Best of luck in your search.

My truck is a long bed 2WD. I'm not sure what evap. emissions is, but I took off ALL of the emission controls, including the catalytic converter. She's bare knuckles now.
Do you know where to get a non-EEC tank? How about a large tank sending unit? I just bought a sending unit and I thought you adjusted it for the larger tank. Here is the one I bought: https://www.summitracing.com/parts/SGT-FG73A

Here are 2, there are many others:
F Series Pickup
38 Gallon Extra Capacity Gas Tank | 1973-79 F100 - F150 - F250 | LMC Truck
I'm fairly certain that sending unit is for the standard 19 gallon tank. You can use it as is, BUT it will only pick up fuel to the middle of the tank. So you would always have 19 gallons of fuel the pick up never reaches. As I stated earlier, you will have to modify the pick up.
