Electrical fuel pressure sensor?
I'm thinking in terms of installing a fuel-pressure sensor for my low-pressure system so I can check how things are going; it'll be very useful if I decide to install a electric fuel pump. My dad has another truck with this engine, and it has an aftermarket fuel pressure gauge... But it uses an actual fuel line going into the dashboard. I, however, don't like that idea; I want to use an electrical sensor and gauge.
Now, I was thinking I might be able to use an oil-pressure sender, provided I can find one that's an actual sender and not just a switch, but I don't know if it'd handle the diesel well enough, or what to look for on ebay to find one.
Any suggestions, guys?

I think it would handle the diesel fine, but the trick would be finding one that could accurately show such low pressure. Our trucks only need 5-7 psi fuel pressure.
Just a quick search and they're out there....and some are super expensive...

I guess if you really like blinging out your truck, there might be a point. But I doubt its necessary. You'd be better off spending the money on a spare fuel pump (mechanical or electric whatever you like) and keeping it on the truck with the tools to change it. The fuel pumps on these trucks last a long time and they aren't hard to change if they fail.

However, I'm not concerned about the pump failing; I would like to set myself up with a tell-tail that will alert me when the pressure drops due to air getting in the line -- i.e. when the tank is empty -- hopefully before the engine loses power and I can switch tanks without slowing down.
I expect that whatever sending unit I find will have to be calibrated against a known pressure-gauge standard(i.e. pressurize a line up to 5 psi according to the gauge, read the resistance, repeat for values between 0 and 15), and a correct resistance between it and my gauge determined.
Can you suggest me some part numbers that are actual senders and not just switches?
