FASS Pickup Tube Material?

[Axion]

Well, finally got my tank dropped to put in the pickup tube for my FASS. Problem is my tank doesn't look like anything in the pictures in the installation manual.



There is a nice spot to put the pickup tube but the tube supplied with the kit is not long enough. The rubber grommet is where I am going to mount the pickup tube.



Does anyone know what the pickup tube is made of? I have a Metal Supermarket near by but want to make sure I get the right material so that I don't have problems in the future.

Well, I went ahead and bought an appropriate length of tubing in stainless steel. It was a little more expensive than regular steel tubing but I figure it ought to hold up without any issues. The hard part was getting one end threaded. I finally found a shop setup to handle the harder stainless. Other than the extra running around it all worked out ok.

That should work just fine..... we use, i think, just mild steel... .....



Also, we are finding that the tubes are working better more tward the center of the tank as well... ... at the 9:00 or 3:00 positions... . so you should be set.



Your tank is differant then any i have personaly seen..... what truck you got?

FASS and TST R-49

Dan, is there a way to wire in the FASS to keep it running during a TST R-49 cool down cycle? Or, is it even necessary that the FASS runs for the last 3 minutes of idle cool down?



Thanks, Bill

Billua do you not have your FASS tied into the factory harness? The ECM will tell it what to do, even if it were not running the FASS system has a bypass port to alllow the injector pump to suction siphon past the FASS itself.

HotRam, my Fass is wired direct from a keyed hot fuse to it's relay... That was the spec layed out in the install directions.



As long as the bypassing doesn't hurt anything, I guess I am OK with the suction feed during the idle cool down.



Thanks, Bill

The FASS will go into bypass mode when shut down and the engine still runs. The CP3 is not like the VP-44 in which low fuel pressure will damage it. (Look at a D-Max..... the CP3 is the only thing that pulls fuel from the tank).



BUT if you wanted to allow the FASS to run, it would take testing circuits with a test light to find which one stayed on when the engine was in cool down mode. Move your power source to this fuse and it should work fine. Just make sure its 20A or higher.



hotram03,

The harnesses for these trucks (05+) are different. They are not a plug-and-play style like your truck. BUT we are about to release a harness for the 05+ trucks that will be plug-and-play. No fuse taps or cutting wires. Just plugs up in between the connector at the top of the tank and has 2 wires that run to the battery.

Dan, thanks for the reply... Any chance I might be able to order the retrofit harness for a clean install?



Cheers, Bill

When the harness becomes available, it will have its own part number for purchase…. . and honestly…. they should be in anytime now…. I got the prototypes here next to me…. .

Diesel Dan;



Sorry for the delay in getting back to you. Nothing too out of the ordinary for my truck. Just a Canadian 2006 Mega Cab. Maybe the tanks are different for Canada?



The hole I drilled for the pickup tube worked quite well. You just have to be careful to be far enough forward that the bottom of the tube clears the baffle attached to the bottom of the tank. The fitting has no obstructions when the tank is put back in the truck either. It sits just below where the cab and the box meet.



The rest of the install went pretty smooth. I might suggest a slightly longer wiring harness for kits going into the Mega Cabs though. I followed the factory wiring up to the front of the truck and was about 2 feet shy of the fuse box. Not a big deal really, I just soldered in some extensions before I soldered the hot lead into the cigar lighter wire.



I'm going to build a thread with some pictures of my install once I get back from a short camping trip with the family. Thanks for the help.

2 Ft? Really?! I will have to look into that... . that is one thing i dont get complaints on..... actually its the other way around with the harness being too long... ... . and rather be too long than... . well you get the point..... :-laf



I had a guy install a draw tube over the baffle in the tank. It took us a while and the guy coming up here in person for me to figure that one out. The truck would run fine until the baffle would get sucked up to the bottom of the tube and shut the truck down..... then it would drop... and the whole thing would start over again... might go 5 mins..... might go 1 hr... but always did it... ... i about fell over laughing when i dropped the tank and saw that... . more out of frustration at the installer. . but glad we found the issue! :-laf:-laf

Thanks Dan. I will be looking for it...



I really like this FASS~

I finally installed the Fass system that I won int he refel at MM07. Wasn't too bad of an job, only took about 9 hours or so. I ended with about 1. 5 feet of hose left over, and the harness made it up the the fuse center on my 06'. The deviation that I made from the distructions that DPP sent with the unit were for the power to the pump. I added a relay, supplied the relay with clean hot power from the lug on the side of the fuse center ( fused the relay at 30 amps). The relay is triggered from fuse position 33. This allows the FASS to run ONLY on ignition/ run and continues to run during the key off turbo cooldown time that goes with the edge juice. I was reluctant to power the FASS from the cigaret fuse port as I already use that spot to power

some other accessories, I also frequently have the ignition switch in the ACC position when parked to power these other accessories, and did not want to have the FASS consuming energy while the truck wasnt running. I also used an accessory fuse tap, this allows the original fuse to still protect the circut it was designated for, but allows the use of a separate fuse to protect the accessory you are powering ( in this case a trigger for a relay). These fuse taps are a bit pricy , 8 bucks from NAPA, but I feel they are worth it in the long run. Along side of posibly drawing to much amperage through the OEM fuse bay, they don't cause any damage to the bay by widening it out. Such like those that cradle the tab on the mini ATC fuses. Just my $0. 2 , I suppose that we must make adjustments to installations to fit our individual needs.



One thing that I would love to track down would be some sort of plug or stopper for either the banjo fitting, or the OEM quick connector( at the EOM fuel filter) to keep dust and dirt out of it, should the need arrise to put the OEM fuel system back into service just incase the FASS system fails for some unforseen reason. Right now I have a heavy weight plastic bag covering it and sealed it off with a nylon tie wrap. Oo.
