I've recently purchased some cheap gauges from JC Whitney. I'm not sure how they''ll perform, but they were cheap and should provide some entertainment during installation one weekend. I bought a electronic oil pressure gauge and sender for $20. This seems suspiciously cheap to me. I plan to use this as a fuel pressure gauge for my injection system. I have a VDO sender and guage for my oil pressure. I was going to get the same gauge and sender for the fuel, but saw this el cheapo set on the Internet. My plan is to put this inline, someplace after the fuel pump, maybe even under the van. I might even take the sender voltage from the line that powers the fuel pump. Does this sound like a reasonable plan?
I also ordered this cheap voltmeter for $13. http://www.jcwhitney.com/webapp/wcs/stores/servlet/ProductDisplay?catalogId=10101&storeId=10101&langId=-1&productId=218997&mediaCode=ZX&appId=384858 My plan is to use the voltmeter on my auxiliary battery, permanently mounted. I plan to leave it hooked up all the time. Though, I might put a toggle switch on it. Even without a toggle switch, I think that the current draw is so low as to not be a problem... right? I would use switched voltage for the backlight.
Finally, I got this $40 air-fuel mixture gauge that I plan to splice into the oxygen sensor and power from switched voltage. http://www.jcwhitney.com/webapp/wcs/stores/servlet/ProductDisplay?catalogId=10101&storeId=10101&langId=-1&productId=221860&mediaCode=ZX&appId=385055 I'd be interested in hearing people's thoughts on these plans.
