Electric Fuel???
Ok I have a question, I know everyone says that we can't use a Airdog or Fass system because we have two tanks, but what would keep a guy from tying the two tanks together like on a semi? Also if this is possible would you have to delete the fuel bowl or could you just delete the pump in the valley and pipe it into the hard line locations? And last but not least if I did delete the bowl would i then have to run regulator?
Thanks guys, just something I have been thinking about.

I know that you will need a regulator if you get rid of the stock bowl.
As far as plumbing the two together it will have to be in a way that the both fill up the same and get used the same and in a way that one doesnt syphin into the other. I guess it could be done but probaly be easier using a SD fuel pump and aftermarket filter set up.

I was thinking of making it so you fill up from the rear tank since it sits higher than the front. If you tie them together than the rear tank would then fill the front. Would tHis work? I would then only run one return line.

I thought this was a pretty slick deal myself. I might try it one day.

I have looked at that setup and the one on beans site but I was trying to look at a cheap option without building the whole system. A airdog system is only $500 or so and if I dont delete the fuel bowl then that is really my only expence. I just dont know if it would work. I mean is the fact that we have two tanks the only thing that is holding us back?

The crossover pipe system works decently for big rigs, but you still have to use the right side pump because the crossover pipe is not big enough to fill the opposite tank. So you would need to make the x-pipe big enough that it flows good. I imagine you could just pull the tanks and put a 3/4 hose on the bottom and top of the tanks it would work.

You could still fill up using both fill necks and if you tried filling the front via the rear it would take all day. The same as a semi with saddle tanks, even though they are connected you still use the satellite pump to fill the other side.

Satellite pump? Geeze must be driving something newer than our 78' Katy Whopper! lol.
Can't you just remove the rollover valve? IIRC it's that valve along with the vent that make our trucks sometime impossible to fill?

I learned on a 63 B61 single axle with a 35 ft tanker behind it, the 1st one I owned was a 74 cabover freightshaker with a shiny 290
Yeah, you could remove the valve and grommet but then you have to fill the hole and have no vent. I think the Wacker sealant would seal it with no problems.

Bluemule I see what you mean. Would the low sump in the rear tank flowing to the top of the front tank be able to keep up? Or is this whole thing a bad idea and I sould just bite the bullet and buy the kit? Like I said just something I had been thinking of.

I'm sure it would keep up. You could connect the tanks with 3/8 or even 1/2 line and that would gravity feed the front tank faster than you could burn it
I'm not sure about the FASS but I know for sure that the AirDog would not supply enough pressure to feed the injectors. The SD guys use it as a lift pump (pusher pump) and filtration system to supply low pressure fuel to the stock electric pump

Never heard of it being called a satellite pump before. A B61 is definitely a classic!
One thing about fuel systems is that you want them to be simple in case something goes sour when your on the road. That's why the mech setups are so dependable and pretty straight forward to fix.
I know the FASS system has a lot of there own parts and may make repairs difficult. My brother runs it on his cummins and he's had a few cross over problems. Just a thought.
