Diagnosing Insufficient Fuel Pressure

pressure because we've got a port we can put a gauge out yeah okay yeah it's got the factory schrader valve on the i had a problem like this before but it ended up being that a bunch of rtv came off the hat when i tightened it down and got clogged in the stock so i put a new sock on it and it just had that pump out a couple months ago and there was nothing in the sock so it shouldn't be that if it's if it's dropping pressure then the pump's not doing its job but it's a 450 it's a 400 i think 400 they advertise it as a 400 but i mean that should be enough for this thing yeah so we're trying to rig up a fuel pressure gauge to see this drop in pressure up top which it probably is um something i remembered is when this setup was in the escalade it had one of those hot wire kits on it which basically is a relay that lets the fuel pump be powered directly from the alternator um and this one i just used the factory or factory like whatever came with the harness power feed which is just a little 10 gauge wire i don't even know if it's 10 gauge but it may not have enough nut to power this pump the way it needs to be powered so i guess we're gonna tape my phone to the fender this is a real bad idea don't do this at home we'll give it a shot yeah we'll see if this works at least you got a foam underneath there so if it does fall off and go down to the ground it'll be okay probably hopefully i hope so yeah okay it's rolling i already have some really cool sounds from this at least yeah maybe didn't go quite as far that time but we'll hopefully get some information from it did the phone survive i don't know still there it's still there okay what is the phone battle i have to say for this let's find out
