For 99 owners, where did you tap for your fuel line to gauge. My filter housing doesn't have anything on bottom to tap into like Mike's does. All I have on filter housing is the inline from the lift pump and the out line to the IP, both are on top of the filter housing. Also there are 2 capped ports on top, sorry no pics right now. Is the out line to the IP where I would thread in my tapped banjo bolt for the fuel line. Also, is it okay to run braided line all the way to mech. gauge, don't want isolator. Plan on doing the needle valve setup. Will braided line go into the gauge, i.e. will it thread into the port on the gauge itself, or do I have to do the nylon tubing kit. Thanks. -
I was told the VP trucks are brutal on FP gauges. My Stewart Warner needs some slappen' around to get it to behave right. Only 5 years old and an electronic sensor type, I'm disappointed.The pulsating is what is supposed to be hard on them but, how is that so bad on an electronic one ? I even had the Vulcan small orific to prevent that. Next weekend Source automotive is putting on a mechanical one. Is that what's best? What brand do you guys have that's lasted? Like to know a little bit on how they are made and what type is best for our VP trucks.T.i.a.

Hey guys i have noticed this odd fluctation the last two days with my fuel pressure. What I am seeing is my pressure go from 16-18 psi then it usually starts to fall off when i am slowing down to stop, i will see anywhere from 2 to 5 to 7 to 10 psi with absoutely no engine indication that this is actually happening!!! (i think maybe false indication???) my fuel pressure has always been very steady until last night and today. :banghead:

New fuel pressure problems...I used to have problems with sudden pressure drops, so Installed a Raptor 100 Lift pump. It's worked quite well up until my last 300 mile trip. Now my fuel pressure spikes (up to 30 psi) on long low throttle cruising, and at idle. The electronic fuel pressure sender (Glow Shift) is isolated from the VP inlet by a 16" grease gun hose. Would this seem like enough of a "Snubber", or should I get a needle valve? A buddy of mine has a mechanical fuel pressure gauge. We'll hook it up in a few days and compare readings. I just wondered if anyone else has ever had problems with a Raptor 100 spiking. Idle fuel pressure is set at 15-17 psi.
