    The coolant temp on the 'handheld' showed 'Lo Err' and the manual suggested it may be damaged so I ordered another CTS and O2 sensor just to be safe. My pump and regulator are both Aeromotive and were recommended by their tech support person for my setup. The Holley regulator that came with sniper kit leaked at both fittings so I got the Aeromotive 13105 [that has built in AN fittings] which I really like and coupled it with their fuel pump at the tank end. The sniper manual recommends 59 to 60 pounds which can easily be dialed in with this brand to suit that recommendation. I also used both the Aeromotive filters they recommend [they weren't cheap] and hope that this part of fuel delivery is kosher. We are back home and I already received the 2 new sensors and will put them on today. Will see if the programmer will read Coolant temp and if it runs better. After thinking about the conversations here and Mark's comment on how it may not run as well without additional equipment I am probably going to get the Hyperspark system that Bob suggested. I am gonna' see how it goes ............. I really appreciate what I get from our forum.

    The new coolant temperature sensor worked and showed ambient temperature when I checked it on the handheld. Wonder why or how it went bad so quickly. Not much run time on this motor or sniper. This type sensor, other than the plastic part with prongs, seems durable. Any thoughts ..........
