Hey everyone,
I have a Raptor 150 installed on my 06 cummins, today I recently put on a ISSPRO fuel gauge, 0-30psi. My question is that the Raptor is adjustable, can i turn up the pump all the way up? the gauge reads at 30 now, when i had it set at 15psi and nailed the throttle the gauge would go down to 4psi. so would it be safe to leave it on 30psi is my question?
Thanks
Nick

 

I would set it back down to 15 like it was...................nuttin wrong with 4psi at WOT and long as it dont go below that

30psi is to much......I dunno what the internal bypass is set at ......I think 15????

 

I just finally got my fuel pressure gauge hooked up last night. I was always curious as to what the AD 150 is holding, Well i first started it up after hooking the gauge up and it went to 15psi, and then gradually rose to 18. I took it for a spin with the edge on level 5 and never really got the gauge to move off 18, i had sold the edge but i wanted to see if with the edge, if it was pulled the psi down at all, so after that run, i took the edge off and then just running around town, it is huggin 19psi all the time.... so this morning, when i started it, when i turned the key, it went to 15psi and then after i started going, it gradually rose to 18-19psi, so someone asked me to go turn the key but dont start it and see how long the pump runs and what psi it is reading... turned the key, pump ran about 2 seconds and the psi was at 10psi and then after the pump stopped it dropped to 8 psi, and then went to zero......
