How to plumb a fuel cell ?

I am putting a 4 link on my s10 and decided to go with a fuel cell rather than relocating my stock gas tank. I have a couple of questions about this installation though, like fuel lines. My stock inlets are 3/8 and are slip on but my cell has 1/2 inlets and are screw on. Also, my cell came with a sending unit so I will have to wire the ground to the frame somewhere and will have to run the hot wire to my gas gauge, can I just jump this wire in with the stock sending unit or do I have to run all new wire? One more question before I go, the mechanical fuel pump mounted on my engine block will suck the fuel from my cell correct? I won't have to hook up an electric pump to it.

Answer:

immediately interior the construction of hydrogen as an potential source the economics do no longer help its use. the cost to produce it and the potential ate as much as produce it are too intense. You get much less potential from the hydrogen than it takes to produce it. consistent with hazard in time somebody will locate a thank you to make it possible yet no longer interior the close to destiny. we are closer to arising fusion as a source of potential than we are hydrogen or perhaps it fairly is very some distance off. all the different issues linked with its use like storage and transportation are lots much less confusing to handle. it is the breaking of the bond between the hydrogen atom and the oxygen atom it fairly is the killer. an identical is genuine in case you tried to extract hydrogen from a hydrocarbon or different prosperous source of hydrogen. As to the guidelines of aeronautics and the bumble bee. it fairly is a delusion organic and straightforward. in case you have wings that are too small then you definately basically ought to overcome them speedier.

Use reducers from the 1/2 to the 3/8. Make sure one internal vs. external measurement. Our cell had 8 an (1/2) out and 3/8 (6 AN) lines. So we just got a reducer coming off it. Also it was set up to be vented, which totally screwed everything up, so we found out we had to cap one outlet. It would be better to run a new wire to the gauge. Fewer breaks in the wire. Better current, plus if anything doesn't work right, fewer places it could be weird. We had to install and upgrade our fuel pump, but I don't remember for sure if that was because of the cell or just because it was time to replace the pump anyway. AN fittings are available online and at most race shops, as that's where most people running fuel cells go. Shops are way overpriced, at least around here. Are you putting the cell in the bed, and if so, do you have a tonneau cover? Depending on the type of cap, you may have water issues. Just a heads up. We're working through that one now. Oh, missed the slip on/screw on part- it's very easy to get fittings that will screw on to the cell and have a barb end for the hose. Just be aware that it's pretty much impossible to get hose back off of barbs without ruining the hose, so check your lengths. We had to order new hose to run from the cell to the fuel pump. so we got yellow to go wtih the paint. Because it was available and not really more expensive. Fun.
