Front/rear fuel tank valve

[Diesel Monkey]

Anyone know of a better front/rear fuel tank valve? I noticed the hose connectors on the stock neck the fuel down to about 1/8". Seems like a real restriction. I may just connect to one tank and remove this restriction. I could add a fuel pump to push fuel from the rear into the front tank.

Thanks

If you are running the stock pump and fuel system then that restriction isn't going to be an issue. If you are running an aftermarket electric pump it could actually be detrimental to the pump causing cavitation. The supply lines in the selector valve are 3/8" and the return lines are 5/16". However the lines comming out of the tank are 5/16 on both the return and feed lines. I found one selector valve from Parker I think it was. But I haven't been able to find anyone who actually carys it. I'm sure you'll have to do some wireing as well to get the fuel gauges to work between both tanks if you do replace the selector valve because I think the wireing goes through the valve to send the level signal to the gauge as well.

Yes, I replaced the whole fuel system, back to this valve. No more silly mechanical pump, a real electric pump and a real filter from a cummins
($9.85). I think I will have to replace the tubes front to rear. The rear fuel tank has always been a pain to fill, and nowdays I don't like to pay for a full fill, just the front tank fill keeps the price under the $75 limit at the pump. Ford did a poor job on the fuel system, and a poor job on the autotransmission.

I would like to find a valve but may just plumb to the front and add a small fuel pump to transfer from rear to front.
