Ok I just put my 392 in a week ago, great pressure like 20 idle and 16 WOT. Now I fueled up for the first time tonight. I noticed when I was driving home my pressure was dropping to like 13 some times and when I woul punch it it would go down to 9. WHY? Then one time I put the chip on 6 mashed it and it dropped to 9 did it again 16. Then one time dropped to nothing for like a half of second. As soon as I left off it goes back up to like 20. Doesnt do it all the time though. What do you guys thing I got air somewhere or what? TIA,

Paul

 

Anyone?, Thanx,

Who's kit are you running?

 

What fuel gauge setup?

Electric gauge, straight manual or a manual gauge with a isolator?

Have you changed your fuel filter?

 

Its the glacier diesel kit. I have the juice with the attitude gauge. Yes I changed the filter last week. But what confuses me is why 98 pecent of the time its good.

 

You might want to hook up a mechanical gauge to exclude a bad reading from the Attitude.
