In Tank Fuel Module
 

Ok, so after being stranded a couple times (out of fuel, gauge reading 1/4 tank) i am going to swap out fuel module in tank. The Vulcan performance Modified Liberty Module has been recommened but, a friend of mine has the factory replacement module he bought and was unable to return and has never been used. This module has the in-tank pump in it. What do i need to do to make this work how it should. I have an airdog 100 Pump. I'm guessing i need the Vulcan Draw Straw V but what other mods do i need to make to it so the in tank pump isnt fighting me? Simple, safe way to disconnect other than the obvious and removing it?

just buy a draw straw and do it youself you will save alot of cash that way

so i need the Vulcan Draw Straw V with the 3/8" fitting to match my fuel line from the air dog or can i disconnect the in tank pump on the module and use the Vulcan Draw Straw I? i just need the module for the float to correct my guage. it is getting worse, i have 320 miles and it read 3/4 tank. Feel like im riding my old harley with no fuel gauge at all and stretching out my mileage. Kinda of sucks i have the HUD with my Miles to empty and i cant use it.

Make sure that when you put the Drawstraw in, to put the tank on a set of sawhorses to help alleviate the 1/4 tank issues.

Put the tank on the sawhorses where the tank straps are. The tank is probably sagging near where the intake is.

i was planning on lifting the bed off with my tractor or overhead winch. if the tank is saggin, is it noticable while hanging from the straps?

It could be noticable, not sure though.

i'll have to call Eric at vulcan performance tomorrow to see which draw straw and fitting i need to order.

Pulling the box will leave the fuel tank in its natural resting position. I'll bet you they say to use the DSV. I have one, and its amazing. Using the DS2, depth matters. DSV does not as the fuel module spring hold the suction point down.

If you already have a pump in your tank you can modify that basket VERY EASILY, and make a custom draw tube like I did... all you need to do is remove the old pump and run 3/8th line down to the inlet on the screen. I used some extra 1/2" line I had leftover from my Raptor pump, tweaked it a bit and got it to work, but the fittings on both ends of that basket are made for 3/8" line... heres a picture of how I did mine........

ahhh, 10hrs too late, ordered the Draw Straw V this morning. Thats ok though, i talked to the guy at vulcan and he told me how to reroute my airdog return line to the vent on the pickup.

EggosBrother,

I did something very similar. Here is the link to my thread, hope it helps paint the picture.

the pics aren't showing up but from what you posted, that is exactly what i'm planning on doin. Just to be clear, you removed the pump from the canister?

EggosBrother,

Sorry bout that. I am not sure why, I just clinked on the link and they popped up. Maybe slowdownload...who knows. I pulled the entire thing apart and it was good that I did as getthing the pump out involved some patience, a lot of cursing and walking away from it for about 15 minutes.....LOL.

Hey Oudive, what was your fuel pressure behaving like before you did this kit? I think I'm getting air by mine, but the only reason I didn't order a kit is because I was in a bind for time. Guess I'll be dropping my tank again soon :argh:

empty wallet,

Digging the screen name cause that describes me all day long...LMAO. Anyways, my fuel pressure was like 19/18, after the mod it actually went up to 21 at idle. I just had issues with how I did mine from the get go with the regular drawstraw. I then got a DS that went into the module and it only had 2 ports. I think they now come with three as it seems that the AD return is better suited for the module as opposed to the fill neck. I am very happy with my setup. I am at less than a 1/4 tank and just made a run for some copenhagen. Not issuse with tank slosh like before. I think this is a more solid setup for sure.
