Topic: After market Fuel gauge?

[83yotachad]

Ok I want to put an aftermarket fuel gauge in and I have a 82 toyota truck and I looked at the top of the tank and there is two wire's what's what? I also want to plumb in a fuel cell into my normal tank what I am thinking of is to be able to drop fuel into the tank as it gets low...

[GJToyotabug]

well with the fuel gauge does is actually measure resistance. ohms bassicaly pretty self expainatory i just thought id try and help im just short on time right now i'll post up to give more info unless someone gives it before me oh and by the way

As far as the fuel gauge, I cannot help you out but I can give you a bit of advice on using the fuel cell as a holding cell.

I have had a 16-gallon cell on my rig for a number of years. It is plumbed into the main tank thru the filler vent via a small electric fuel pump. On the first trip out after mounting the cell my rig started running rough. When I stopped to found out what was wrong I had fuel pouring out of the charcoal canister. What was happening was the vacuum in the fuel system was pulling fuel from the cell, which was overfilling the main tank causing it to be pulled into the C.C. and being sucked into the engine causing a “rich condition”. I fixed this by installing a “ball valve” on the transfer line between the cell and the main tank.

Mount the vent as high as you can and use a fairly large hose. If not you will be pukeing fuel out of it as the fuel expands from the heat.

Here are some pictures of the cell mounted, ball valve, and vent.

1st off Thanks ! I have to ask does your cell have four nipples or just two mine has 4 Id assume one return one vent and two out  to the engine and Id assume that I could tie the outs together how would I know what one is the vent and what one is the return ?  If you have the ball valve there do you just leave it open all the time? Mine is brand new I bought it off a guy and he didn't have any paper work on it and never used it he thinks it's a 10 gal but it looks like a 15 to me. What is the LxWxH of yours? In the last Pic is that a vent and what did you use for the actual vent? With the sump you still used a pump right and I assume you have the pump on a toggle switch? OK sorry for so many Q I am tie 'n' things up to go on 6day wheeling trip and need to have things done by wed ! O one more how do you get gas in that with it mounted under ?

Mine only has three, two on the side at the bottom—feed, one on top—vent.


If you have the ball valve there do you just leave it open all the time?

No, only open it when I am pumping fuel into the main tank. If I left it, open all the time the vacuum in the system would pull the fuel into the main tank, overfilling in and flooding the C.C.


What is the LxWxH of yours?

Have no idea; it has been in there for years.



In the last Pic is that a vent and what did you use for the actual vent?

I have a rollover valve in the cell that I modified for a hose barb and the rest I cobbled together out of fittings I had laying around.


With the sump you still used a pump right and I assume you have the pump on a toggle switch?

I used a small low-pressure fuel pump I bought at NAPA and it is controlled by a toggle switch in the cab.


O one more how do you get gas in that with it mounted under?

I cut a hole in my flatbed for filling.

[Redbeard3261]

Are you just using these as addition fuel capacity dumping into the original tank as needed? I am curious about replacing my tank with a fuel cell that I can mount in bed to free up room under truck for 4-link. Any suggestions?

[OOPS]

Yes, I hate Jerry cans and I have a short flatbed. In total I have about 32 gallons of fuel when both are full. A friend of mine used a Ford van tank mounted where the spare tire goes on both his 87 runner and his 97 runner. The 87 was leaf springs and the 97 is linked.

Here is some information.

Check out this thread on our trip to Moab and see how it works, yes that is his 12 year old son wheeling it in Moab.

I measured the cell, these are approxmate measurements.

W----27"
L-----18"
H-----9"

Thanks !
My Q are kinda a@@ backwards I had this in the shout out box and no one was out there soo..
 
3. If I power the yellow wire w/red stripe then ground the white w/blk stripe I get 1/4 tank if I swap them around I get the neddle pegged on full. I know the tank is about 3/4 full..
 
2.This is the one Iam tryin to get to work ! http://www.autometer.com/cat_gaugedetail.aspx?gid=2454&sid=1
 
1. Hey does any one know what the Ohm range is on the  fuel sender for a 82 toy?

[Dr.Maxwe001]

to find the tank capcity  you say LXWXD divided by 231

Some electric fuel pumps allow flow through, some only flow when supplied with power.  I can only assume your issue could have been fixed by using the latter.
