Fuel cell

[Superdannyboy]

What's up, superdannyboy here.

Question, if I buy a universal fuel cell and mount it to my bed, would I be able to put the stock pump inside and gauge inside? Or how would I do such a thing?

Example, I buy this.

Not sure you could integrate a stock fuel pump & sender into that. On another truck I needed more fuel so just mounted the fuel cell in the bed and ran a off the shelf electric pump into a 90º elbow mounted in the trucks filler neck, with a dash switch. When the main tank was low just flipped the switch to transfer the fuel. Not sure that would work with a pressurized fuel system, might have to loosen the cap to transfer.

You could use a generic pump and sending unit with the right ohm range. Then use a switch to select which tank you want. Same as the older F150's that had duel tanks. That should give you about an 800 mile range.

Hey machinst85 thanks for the input. I'm looking at removing the stock tank and putting the fuel cell in the bed to help the rear suspension performance. I'm wondering if I use the stock pump if I need it at the same height as the current location for it to work properly or what my options are.

The tank height wouldn't matter. If anything raising the tank would take some load off the pump since the fuel doesn't have to go uphill anymore. The problem would be with the evap system. If you don't transfer it all to the new tank you'll have a check engine light.

Does anyone know the ohm range of our sending unit?

 

[machinist85]

All Fords from about 1990 and up are 16-158 ohms

Ok I think I found a good fuel cell to mount in the bed with 2 35" spares. This one comes with the sending unit but no pump. Not sure if I could use the stock pump or if I need to get a generic one as mentioned earlier on the thread. I've never hooked up a fuel cell so I'm not sure how to attach the evap system. Any suggestions? Also, can someone explain what each fitting is for? How is the pump attached inside?

If you were mounting it in the bed, couldn't you just gravity-feed the stock tank with no need for a transfer pump? It would backfeed the main tank so it is always full.

Yes you're right because of the height. But I'm actually looking to dump the stock tank in order to run a 4 link in the rear. That'll be a ways down the road but for the time being the fuel cell in the bed will help my rear suspension performance anyway. I've designed a bed cage and will order the tubing soon and can get the fuel cell mounted in the bed but I have no idea how to route everything to it. So I want to drop the stock tank, use the fuel cell in the bed, and then eventually one day when I can get a wider rear end I'll attach the 4 link that I'm designing now.

My fuel tank got here. It'll go in this location when I build my cage soon. It's all designed just need to order parts and work on it one day a week. I'm keeping the leaf springs for now.

Ok so I have a question you guys. I have the fuel cell and I'm looking at the fittings and fuel lines and I was overthinking it. Seems I just need to run

1) A hose from the sump to the pump
2) A hose from the top of the tank to the evap canister
3)A return hose from the pump to the tank

My question is if I use a -10 for the outlet to the pump, a -10 to the evap canister, and a -8 to the return hose will that cause any problems? I know if the hose is too skinny I can starve the pump but are these too thick? Those are the sizes of the -an fittings welded to the tank.

 

[Superdannyboy]

Ok so I found out I can use a reducer to reduce all of the fittings to whatever size the stock fuel lines are. Something like this.

This is a crazy project. Please keep us updated. Good luck.
