Fuel tank switching
Alright, I just scored a 5 gal aluminum fuel cell. My main plan is to use it as the IC water tank. But I've been thinking. (Bad way to save money.)
An idea popped up. It concerns the fact that my ECM has the ability to jump to a different fuel and spark table at the flick of a switch, nothing else needed. I use an electronic boost controller as well. So, instead of putting water in the fuel cell, I was thinking of, well, fuel. Race gas, to be more specific, in addition to the regular gas in the tank.
I'm trying to figure out a way that I could plumb in the tank, using an electronic valve or something of the sort, without getting the fuel mixed up. That way I could have the ECM and the boost controller wired up to one switch, to switch to high, basically. Then I could run an ouput from the ECM to a relay for fuel pump numero 2. The switch is flicked on, fuel pump 1 switches off, pump 2 kicks on, the ECM delays the table switch for several seconds, and the boost controller switches to aggressive. Almost instant HP.
So, I'm trying to figure out how to plumb the damn thing. Ideas are appreciated. I just dreamed this up last night, I've been web surfing for valves and solenoids and all that good stuff since then. My idea might very well be fundamentally f#!*ed. I also need to get a new fuel regulator, so I'm definitely going to get a multi-port reg, regardless.
Thanks,
Nate

Indy DOHC Turbo SD4.....someday.
Oh, and f*ck the envelope. (RFT Insurgent)

Hmm...I was thinking overly complex. Drr...guess I have my days. I suppose I could do the same for the return line. I'm going to see if I can fit it underneath the spare tire, and I'll be ditching the A/C crap since I don't have a compressor anyway, so I might see if there's room in that area also. So, as close to the front bulkhead and as low as possible.The Dark Side of Will wrote:Normally open solenoid on the pump gas fuel line, normally closed solenoid on the race gas line. When energized, pump gas valve closes, race gas valve opens. Switch valves and unplug for track days.
Where are you gonna put the fuel cell?

Hehehe. I was on the Ray Hall turbocharging website last night making sure to read up on methanol. Maybe a little nitro thrown in the mix. :thumbleft:bryson wrote:Step it up a bit -- run methanol Only for track days, though, because it doesn't lubricate well, but imagine how much power you could make...
The tank came in today. It's pretty big, I may ditch the spare. Gonna go out and look this afternoon. Pretty nice though, AN fittings and a sump welded in. Imagine a 9x12x12 aluminum tank and that's it.
Guess I'm gonna have to look for another IC tank.
Had the camera out, so I took a pic for the hell of it. Seems like all I've been doing lately.

I got a Paxton external pump yesterday, but I'll get another for the aux tank. Should give a little bit better response time from switching tanks.crzyone wrote:There are a few trucks I know of that had a tank switcher, a mid 80s ford F150 is one of them.
Will you be using an external fuel pump so it works for both tanks?
Messed around with this some today. Removed some of the A/C junk, and I can get it pretty low as is, the hood can close with plenty of room to spare. If I remove the lower plastic trim by the bottom rear of the spare, and make a sheetmetal (or fiberglass I guess) bucket for the front bulkhead, I can get it another 6" lower at least. If I continue with my plan to use it as a fuel cell, I can still fit another smaller water tank on the passenger's side of it. I'm also going to put the battery around where the spare jack bracket is, I think. Then the water injection tank will go in the back. I'm gonna ditch the spare for local drives . Too much shit to fit in there. It'll probably weigh 4000 lbs by the time I'm done. :blah5:
