So just one tank and extended the floater for the fuel level, what are these draw straws? I keep hearing bout them but never see an explanation for them...

 

i took a brazzing rod and made the float arm ,as for the draw straw i welded a 1/2 bung in the bottom this is mine


Here is a draw straw setup
Draw Straw I 1/2 in. draw tube and 1/2 in. pushlock fitting

 

ok so if i do a draw straw from the top, i just plug the lines in the original sender and cut power to the sender, but leave power to the fuel level gauge wire?

 

yes but there is not much room above that tank keep in mind

 

ok i will, thanks a lot it definitely helps me having people able to answer questions and not turn away. i will be able to continue with my build now if i got anymore questions ill give you guys a hollar

 

got myself another problem, since the motor moved the trans back 3 inches, i used a 5r110 out of a 04 powerstroke since it was a direct bolt in with my trans x- member my shifter cable isnt long enough what do i do??!!

 

I used the factory gas sending unit and just removed the fuel pump and replaced it with a steeltube

 

What year cummins are you putting in? The 89-93 have a vacuum pump. The truck should already have a fuel return that selects with the supply line being used.
Could you weld an extension on your tranny selector to reach the cable?

 

I've got a 94 with a ppump, its weird cause if I extend the bracket that the cable clips in the actual cable won't be long enough its like the cable itself needs to be longer

 

ok got myself a question for you guys... will a 6.7 cummins grid heater work on my 94 12v
