Mount it toward the rear of the tank. That way when the level gets down around 1/4 tank you won't starve the pump under hard acceleration.

 

if i mount it at the back of the tank, then what about if i go down a steep grade. it could be sucked dry couldn't it?

 

Mine is in the factory module with the bottom removed (Draw Straw).

The location I prefer is close to the stock spot. I would look over the tank and under the ned to be sure there will be no clearance issues. A small mirror helps here.


I have run my tank down to the 'E' and have never run out of fuel. If the tube is installed at the correct height, the center of the tank is a good location.

Middle of the tank at 1/2" to 1" off the bottom is what I've always seen done with these. and that's exactly where your stock tube draws from.

 

ok thanks a lot guys! hopefully i will get it done tonight.

 

Just keep a full tank of fuel at all times. I'm thinking from a racers perspective and it didnt even cross my mind that some of you guys actually use your trucks offroad.

I've been testing one of the draw straw type tubes and dont like what I'm seeing. I'm going back to using the fuel pick-up mod on the factory sender and bucket. It always keeps fuel available to the pump no matter what you're doing with the truck and doesn't starve under hard acceleration.

 

Myself, I did away with the whole top feed completely. I drilled a hole in the front of my tank and used a fiitting to run a pickup tube to the center of the tank right out to the fuel lines. I don't fight gravity anymore, now gravity pushes fuel for me instead of pulling it away from me.

 

last night i didn't get the install done but tomarrow i will. im thinking of moving the breather for the filler neck and putting the draw tube there. then the draw tube would be right next to my catch basket in the tank in the middle. if anyone else has any other ideas let me know.

 

That's way too high off the bottom of the tank IMO.

Mine is about 1/8" and slash cut at about 30 degrees.

The reason these guys run out of fuel with 1/4 tank showing is because of improper mounting depth.

With the stock Dodge module that not necessarily the case. The sloshing action can easily uncover the pickup area. Add to that the intank is in a fluid "puck" and it's easy to see how that has it's own set of issues.

With the high volume aftermarket pumps, the puck can be sucked dry and it can't refill fast enough through the fabric to keep up. Also, the return dumps the fuel on top of the module from the factory. Again, I have seen cavitation due to the restriction of the screen.

I had come up with a preliminary design to address some of these issues and still give the off roader and racer fuel in the pickup area. I don't know if it will go anywhere.

The ideal tank for any application would be very tall and skinny. Like a pop can. Bottom sumps are out for all but the drag race crowd with the factory type setup. Although with some work, a skidplate can be fabricated. BTW, I have a bottom sump design as well.

One thing is for sure, there is more than one way to skin a cat and my way is just my opinion of what;s right.

I was always told not to put it to close to the bottom so that it would pick up the sludge and junk off the bottom. Personally my pick up tube sits on the bottom but I was always told that I should change that to prevent this.
