I'd be sure to use somethng to either strap that tank to that jack somehow like the tranny jacks use or use the straps to lower the tank like I put in the guide cause even if you run your tank down to E, without siphoning it you will still have upwards of 10 gallons in there sloshin from one end to the other once you pull those metal straps lose. You really don't want that tank bouncin off the ground or you may be buyin a new one along with cleanin up a mess a diesel fuel.

yep its a little tricky do drop a tank with one jack, even harder by yourself with a jack that doesn't reach.

but the easiest way to do it is have someone help you, im not as fortunate

That's why I just use the straps described in the guide. Most everything I do is by myslef so i have to find ways around a second set a hands.

In the past I also tack welded a stell bar across a car jack and strapped the tank to that but that was to much work, I like simple.

First, before you go pulling tanks and changing filters....i would defiantly try a few tests to find your problem, rather than just tossing coin at it and hoping it will fix it. Granted the draw tube and filters prob will help in the long run, I would feel much better we tried to identify your issue first.

Know fact: The VP-44 will beat an electrical sending unit to DEATH! You need to run a snubber if you don’t already have one....here is a link to Auto Meters version.... Anyone that carries Auto Meter can get that part. What you need to do is confirm your gauge is reading with a known working mechanical (As aforementioned). I can honestly say that the number one reason we see pressure issues is due to gauge error.

Second, you need to try to pull fuel out of a bucket. See if the pump is quieter, and pressure comes up. If you see an improvement I feel is time for a Draw Straw or our STK.

i already have a snubber but maybe its not working as well as the autometer one would. Hmm, anyone wanna PM me a price on the AutoMeter snubber?

Also, how would i go about sucking fuel out of a bucket......how much fuel do i need to do this and what do i pull off the truck and where to do it.

Just pull the fuel supply line off the top of the tank connected to the module and put that end in a bucket of fuel. A couple of gallons is more then enough. This is how you flow test the LP. Bump the starter nd see how much fuel is drawn up in the amount of time the LP runs.

Its real easy with the FASS:

Pull your pumps return line going to the fill neck. Put the return line in the bucket and run the pump for a few mins. To get it about 1/2 way full or so. Then shut the pump down. PUll your suciton line off the tank moduel. Put both lines in the bucket and run the pump. Check pressure and listen for noise (Or lack there of). Once you get done, put the RETURN line back on the filler neck and run the pump to suck the bucket dry (Dont let it suck too much air or you might have to crack the fuel filter loose to rebleed the pump)
