Wanted to add a note for future reference, having spent half the weekend researching fuel level sensors, that for E85, there is really only one choice,
and that is a WEMA stainless-steel magnetic float sensor.
Fuel Tank Senders, Gas Tank Senders, Water Tank Senders, Holding Tank Senders by WEMA USA, Inc.
This unit I ordered was only $32 and are available in 1/2 increments, my tank is only 7in high, so the Jegs/Jaz/VDO tube senders that are $100 and limited sizes. These designs seem to be the same as the ISSPRO senders that use aluminum and are not good for E85. The ISSPRO senders are available in inch increments, and are $64,

And finally there is the Centroid
CENTROID PRODUCTS - Computerized Tank Display - Electronic Senders - capacitive fuel gauges
sensor that uses capacitance, so no moving parts and about $60, but it uses aluminum and brass to measure capacitance, and the signal varies by what type of fuel, so not good for E85 or E anything as the signal changes.
Hope this saves someone some time. Was thinking of making my own until I found the WEMA units.
And also let me add that I'm not done with this tank install shown in the pics, so if it looks like its unsafe, it hasn't been strapped down rubber insulated, etc, yet.

I had no foam in my 8-gallon tank in my Falcon no problems at all.
However I do think it may cause the Geo sender to fail as it is a quite weak device, I will probably replace it with a tube type sender, or perhaps something else. I had braided line on my falcon and did not like it, and will not use it again, hard to handle it and it eventually leaked, but you could not find out where because of the braid, but in any case, NHRA rules allow only 6or 12in of it if I recall. I have to run about 4-5ft from tank to engine.
PEX line should last forever, if not in sunlight, which it isn't, and will likely wrap it with aluminum tape, and run it through an alum conduit as well, since I will have the exhaust pipe going through the trans tunnel (which will be heat sheilded as well)
I'd use alum tubing if not for E85. Having trouble finding fittings for small size PEX. I don't know what the PSI is for the Geo, I think the TBI design uses less pressure than port injectors, the PEX is rated at 100psi.
McMasterCarr has Buna-N braided hose, that is good for E85.
McMaster-Carr might get some of this. |
