what do you guys think? Now I am running 8psi at idle and 5 psi on the skinny but I do have a glacier 391 kit ordered that will be here Tuesday.Do I run the risk and drive it till then or park it?

VP 44's are getting cheap---buy em for under a thousand now if you shop around

Sea:\>Drive

Can't give you recommendation but I ran several weeks (albeit was easy on the skinny pedal) on a failing lift pump that I could pull down to 1psi WOT, but she ran a steady 5-8psi at normal cruise. I replaced the lift pump about 10k miles ago and have had no issues since.

Until someone does a scientifically controlled experiment to see how long it takes a VP44 to go south with a dead lift pump, it is anyone's guess.

My personal opinion, as long as it isn't running at 0psi, there is more fuel than the VP44 needs to keep running, although below ~5psi it may not be enough to keep the VP44 lubed and cool.

I think it also has a lot to do with the outside ambient temperature, I don't hear of a lot of 44's going south in the winter time up here, most go south on or after really hot periods in the summer.

If you have a part that fails easy , than do not give it any help .

You will be fine run it. Its about volume not pressure.

I agree with this info 100%.

volume not pressure is the key, the vp has its own 5 psi pump built in it. ive been at 3-5 psi for about 5 years now absolutly no problems.....there was and still is a large batch of bad vp's out there that are predisposed to failure.

When it's your time to go.....it's your time to go.

Drive it. You'll be fine at 5 PSI.

I have 206K miles on the original VP44, and trust me, even though I'm a grandpa, I don't drive like one. I know there was a time I drove the truck with a dead LP for 5K miles or so twice before I got a FP gage.

I have 284k on my original 99, VP44, I would drive it and not worry about it, low psi does not mean that much in my books, like nitrousn said it is getting volume that is what counts.
I do try and keep some additives in the fuel.
I never worry about filling up until the low fuel light comes on and I drive another 50- 70 miles or so.
(I have changed the original LP at over 200,000 miles.)

I just got a gauge on mine and found out that at some times it would fall to 0psi after a lot of skinny pedal. I have know idea how long it has been like that, but it seems to run fine. Today I put the campaign pump on and it does not seem to run any better with the 9psi at WOT it has now. I would drive it.
