To be honest, I had one years & years ago and had nothing but trouble.
That was when it was new and the knowledge & equipment way different then now.
I did buy a sender for the pump a few years ago, but never put it on, and I'm not even sure where it is.
If I find it this winter, I will be doing what street shaker did, you can never be too safe??
Engines aren't cheap, neither are pistons!!
i had one and it worked with out failure for a few years. a buddy rented the track for a club race and i chased problems all day long instead of racin with all my buddies to only find out when i got it home that the pressure sensor was bad. all i had to do was unplug it and plug them together and the problem would have been solved. haven't ran one since
