An idea...has anyone tried it?

[Jim Barbero]

I have been thinking about adding a second tank to the cherokee. I have one available that will fit sizewize (it is out of a 89 pontiac of all things) but I was thinking about having both tanks fill from the same filler tube (and maybe making it have a few less bends at the same time)

Anyone see any potential problems with doing this? or would it be better to run a second gas filler tube?

I scored the whole car for free, and it has awsomely comfy seats in it, They are going in as well, but that will take some fabrication of mounts - Oh well... ;)

And Bose speakers as well, and the stereo with the electric tuning on the wheel (need to see if this will fit) and it had onboard electric air which is going in. This is going to be fun. :D :D

If ya did use one filler....how will you divert from one tank to the other? I say two fllers would be easier. How about racecar type quick fillers....that'd be cool (but $$$ I'm sure)

later,

Actually, the racecar fillers are not super expensive, but I don't think I want ot get QUITE that high tech.

I was thinking about some sort of a T or Y pipe to where both tanks were just getting filled at the same time, then having one of the electric switches to switch from tank to tank.

The only potential problem I see is that I think the fuel return would only go to the front tank, but if they were connected to each other that would not really matter.

Do those electric tank switches work with mechanical fuel pumps? I thought they jus switched from one in-tank pump to another on injected rigs (At least the Ford ones that i have seen are like that)

I have dual tanks. It's a real love hate relationship. They are good because I can drive my rig for >2wks without worrying. $50-70 a fill up though. I can also take long trips and drive until I'M tired not the Jeep.

The fuel is split via a "Y" at the filler hose. THere are two vent lines and obviously two supply lines(one each tank). THe electric valve will work for mech. pump, however I think on warm days(90+) it has probs getting fuel from the back, or it could just be a vapor lock condition. Either way switch tanks good to go. The valve will also control your fuel gauge so only 1 gauge is needed.

Now to the hate part. I have the same fuel gauge probs everyone else does but x's 2. I have replaced both sending units and ohm checked the wires. The rear is the most problematic, it runs high sometimes then drops, or can take five days to move. I did notice however that after changing all battery cables and upgrading to a 95 amp alt(electric fans) that this seems to of have improved (ground??).

Sooooooo good luck. My rig came with the tanks but I know it like I own it. I can't tell you where the tank came from but R.B.'s site will tell you how to modify a Bronco tank. I think there is a company named Aeroquip they manufacture locally as well.

Hope this helps. Let me know if you need pics/answers/moral support.

Bigwillys - The aftermarket switches come in 2 varieties. With 3 (no fuel return) or 6 (with fuel return) ports. I have used the ones with 3 lines several times with mechanical fuel pumps with no problem. ave never tried the other type.

Dave, thanks for the info. I was planning to just use the guage that is in the car I am getting the tank out of, so both would have their own guages. Works as a good failsafe if a sending unit goes out too (at least you know when one tank works smile.gif)

I was thinking about leaving the elec. fuel pump that is in the tank there and wiring it to a toggle (again, just in case) This would probably allieviate any fuel problems, but it is nice to know to watch for that.

Anyone know if a GM pump will pass through if an external pump is run?

Jim,

My bronco tank also has the elect internal pump still inline and prewired...'just in case' ;) it should flow thru the GM models just the same....

My wag had dual tanks when I bought it. I believe the tank in mine was built by a company called Trailblazer out of Boise, ID.
Theres a sticker with the name and phone number. Wife has the wag so I can't go look right now.

My setup uses only one filler. PO told me it fills the auxillary tank first, which sits higher than the stock tank. Than it supposedly siphons down into the main tank.

I haven't really paid any attention to it, or how it is setup, because I haven't had any problems with it. I'll take a look at it this weekend, see how it's plumbed and get that phone number if anyone wants it.

I added an auxilary tank to my car last winter with a "Y" in the filler tube. This winter I will add a second filler neck. I have a LOT of ttrouble filling both tanks. Somehow it seems that when the first (stock) tank fills then the splash back turns off the pump. I never know for sure whether I have a full load or not. When I'm spending several days off-road and its 50 miles to the nearest gas station it matters.

It has been kind of odd to run out of gas in the main tank and switch to the auxilary and within a few miles the auxilary tank has emptied into the main tank; I presume thru the return line off the fuel filter.

Maybe its my plumbing, but it seems easier to just add a second filler neck.
