    Many of you guys know I like to do things a bit over the top. In my never ending quest for the best suspension possible I am now looking into fuel cells. Which really isnt a question. My questions are, what is the OHMS range of our sending unit and what is our fuel pump flow rates and pressures?

    Once I have those figured out I should surely be able to wire in whatever I need to make this happen.

    That's a great question. The FSM can probably answer the sending unit resistance. But if you are considering a fuel cell, you're probably better off using an aftermarket fuel pump.

    Planning on using aftermarket, but need to know what our factory systems use so I can try to match it as best as possible or slightly up it since top end is getting rebuilt with an SC

    So. This goes back to my old Ford knowledge. Guys have run 302s with 32# injectors on 190lph fuel pumps with great success. So when I redid the fuel system on the Mustang with stock 19# injectors, I put an aeromotive 190lph pump in the tank so I'd never have to worry about it.

    Take that for what it's worth

    I would think any excess fuel would just return to the tank anyways. Extra fuel flow would be great for the larger injectors of the SC setup.

    No wish to hi-jack the thread but if the OP of somebody else would be kindly patient enough to explain....

    What would be the advantage of a fuel cell relative to a quality battery (or two)?

    Thanks for the clarification IM1RU.

    Wiki 'fuel cell' and this is what you find: Fuel cell.

    As soon as I read your question I knew what you were thinking.

    Although, with the proper fuel cell technology, one could power an electric vehicle quite well.

    Some one really should come up with another name for the gas tank version..... The hydrogen burning fuel cells have been around considerably longer.

    My super quick and dirty sketches of idea #1.

    If you figure out the volume by the measurments I have pulled you end up with 33gallons. I don't really want THAT big of a tank as the weight starts to get a bit much aft axle. If I can build it to about a 25gal setup I would only have 150lbs of fuel weight. Nothing a good set of coilovers or airstruts couldnt handle.


    As for fuel system research. It looks like I should be able to flare the hardline on the frame and put a AN adapter fitting to it. Things are coming together. Now to figure out fuel guage... E1B26344-BA06-453D-945B-2C4926AAD027.jpeg
