Thinking about a FASS help please comment (leaving home soon!!)

How hard/ long is it to install in a 06 mega.

I was thinking of the dual filter and pump assembly.



I was going to keep the orig stock filter housing in place (have filtered fuel still go in to the orig filter location, with the stock filter in place).





I have no mods on the engine but use it for work, and towing.

( future programmers most likely. )



*** I am about to leave Friday from Texas to Utah then California then back** About 10 days total. .



Is it to close, in terms of reliability, to install before my trip??



TIA

Personaly i wouldnt do it right before a big trip like that. No time to work out any bugs in the system.

You can install the FASS in about 6 hours continuous effort. You can plumb to the stock filter, but I did not on my '02 nor am I going to on my wife's '03.



Why is it important to install the setup before you leave? Just curious. You can install the setup without problems if you follow instructions closely and don't take any shortcuts. You are tightening brass fittings, so be careful to not overtighten. Wrap teflon tape clockwise in threads a couple of turns. If you decide to do it, give yourself at least a couple of days for unlikely event of any problems.



IMHO, the two most time consuming/difficult parts of the install are replacing the lines on top of the fuel tank and installing the bracketry. I spent a couple of hours today just drilling/installing the mounting bracket on the cab mount. Short bed much harder than long bed. Also, recommend you run the fuel tank almost empty (1/8 tank). I recommend loosening the fuel tank straps to allow tank to drop a couple of inches... it's easier to replace the lines.



This is all I can think of. If you are mechanically inclined and have the tools, I'd go for it. If not, save it for later and give yourslef plenty of time. Let us know what you decide to do.



Shoot me any questions if you have any... I check e-mail in the evenings.

I put an Air Dog system in over a weekend. First day was going through the box assembly of the mounting bracket and finding a mounting location, also pulled the bed off. next day was plumbing and wiring. The install could have been done in one day no problem. It is all pretty straight forward and not that hard. If you are having bad feelings about your current lift pump I would do this project before you leave. I was having bad feelings about mine. Ignored them and ended up with the truck dead on a long bridge at 11:30pm with my girlfriend driving solo.

Install time

Do not start before a trip! I can send you pics of mine on a 06 mega cab. 6-8hrs on the install, you will want to take your time.

dstafford pics would be great!!!

FASS instructions/brackets could be improved

I just installed the FASS 95 and I'll mention a couple of things. My truck is a 2WD QC short bed and I didn't like the mounting set-up, (outside the frame rail where debris from the front wheel is thrown up). . I ended up making a bracket and mounting the unit on the trans crossmember up a bit higher, (no transfer case to impede on my 2WD).

My truck has the OEM pump mounted on the fuel filter housing so I only had to unhook the supply line from the top of the tank, which is easier said than done. Ended up using a pair of curved needle nose pliers and finally got it off while working through the left rear wheel well area.

The wiring wasn't bad but was way too long so I spent some time and shortened, resoldered and heat shrank the connections. The plumbing and hose connections require a bit of care. Use teflon tape on the pipe type threads and be sure to oil the AN fittings. Also a bit of oil and heat helps the rubber tubing go on the push-lock fittings.

I filled the water separator and fuel filter with clean diesel and it started right up. The test drive was great and the pump holds 15-16 psi and only pulls down a slight amount if you "get on it. "

Now here's the part that threw me for a loop.

After coming back from the test drive the truck was parked on the concrete apron outside my shop. I noticed a spot of diesel under the truck. I thought it might be from the unused / disconnected old supply line. After moving the truck inside the shop it continued to drip. I felt sure I had damaged something on top of the tank.

It was getting late so I moved the truck and left it outside on the gravel overnight. The next day I said, "what the H*ll", and decided to remove the bed to find out what was going on. (I'm lucky as I have a John Deere tractor with a front end loader with forks as well as a 10,000 lb lift in my shop to make the job easier. )

Pulled the bed off and sure enough it appeared as some residual fuel had exited from the old line. I cleaned it up and took a test drive with the bed off and upon reinspection on the return I didn't notice any more leakage. However, after the truck had been sitting about 30 minutes the fuel was dribbling out agian. WTF???

The new install completely bypasses the old line and OEm fuel filter assembly and I thought I had drained the canister completely but when I went to open the drain valve again I heard a bit of pressure release.

So here is my theory: An amount of fuel is trapped in the low spots of the line and heat soak expansion must cause some explusion of the residual fuel. Eventually, it should stop but I toolk no chance a capped off the old supply line.

I also called Geno's Garage, (they're great by the way), and mentioned this to Brandon who indicated several others had had this same thing happen to them. If the FASS instructions had only mentioned this or told you to cap or remove the old line it wouldn't have been an issue. But no I spent an extra day removing and replacing the bed just for the heck of it. #@$%! #@$%!

Anyway it seems to be working great. JUst my 2 cents.

I installed my Air Dog in 5 hours with 3 coffee breaks and a barley pop and hotdog break at the end of the job. The 2 systems are about the same by the looks of them Ive seen Fass up close. As for the Air Dog the only thing that I didnt like was the vibrations from the pump when running what I did was to get a thick rubber mud flap from a simi truck cut it and put between the mounts of the pump / filter and the frame of the truck this cut out all vibes and noise except at WOT. My lift pump took a dive on me so I dont know if it was always weak or if the new pump is that much better but there is allot of difference in before and after good luck its not that hard to install. I took off the stock filter and used the G D filter kit to get it off the truck just a quirk I have If it dont work I dont want it around.
