I dont have full details yet, but as far as i know i am going to have (2) brand new pro comp series, electric full sweep fuel pressure guages by autometer. I actually have to wait for my friend to get these from him but it should be within a week. At that time i will be able to give everyone full details on everything you need to know. I called autometer and they said they retail for around $150 from them so????? well if anyone needs one let me know and i will keep you updated as i am updated and will be able to get pics and want not when i get them. thanks
