Cobra Make, Engine: Classic 427, I purchased it May 2005, the kit was bought in 1991. I'm not sure when it was completed! Installed GMPP Connect & Cruise 376/525 with T-56 S/M 3.55 gears about 2 years ago! 1/4 miles is with old setup!

Well got-er installed yesterday, programed the gauge for 0-90 ohms and it was spot on! A gallon or so in the tank read empty! I put in about 4 gallons and it showed around a 1/4 tank! Headed out to fill-er up with some 93*! On the way I decided to play a bit! A sharp left turn and brisk acceleration from a stop sign and the fuel pressure dropped! Approaching the next stop sign I got on the brakes hard, same thing! It took a little over 15 gallons more to fill it, it read full!

I don't plan on any road racing but I still wish I had installed a fuel cell or a baffled tank! FI is totally intolerant of fuel pressure drop even for a second! The plan for now is to do a manual program on the gauge. Set empty at a 1/4 tank and of course full as full! The sending unit is much better than the open float design of the last one! The reading changes as the fuel sloshes but it slow and moderate!
