Universal sending unit help

[McKenna]

Hey guys I have a 1970 C10 I'm slowly working away at putting a 6.0 LS into. I'm just getting to the fueling part now and I am looking for some help on my sending unit.

I have a friend who has offered to make me a tank for next to nothing all tigged out of aluminum so I have found dimensions online for an under the bed style I just can't figure out what I'm going to do for a sender as I suspect using a factory GM unit would be quite difficult.

I guess what I'm asking is what would you guys use? Is there an aftermarket bolt in sender I could give him a template for that uses the 0-90 ohm (I think that's the right ohms for our truck) I'm Just thinking a bolt in unit would be less head ache for him to fabricate

As well would you guys run an external pump or try to find a sender and use an internal one? Pros and cons?

Sorry for all of the questions I just have a dead line as his boss is only on vacation for so long haha and I have no experience with GM fuel tanks this being my first GM truck or EFi conversion

The pros to having the pump in the tank, it [the pump will run cooler the pump [should] last longer[because of the fuel cooling it] and last but def not least it will be quieter by a ton.
The pros to having the pump on the out side of the tank, it is easier to service if needed, it will be less expensive on the outside of the tank. Good luck Jim

Yes 0-90 is the right ohm range. then you could meditate. Ohm Ohm Ohm. Jim

Yes, there are choices available, universal, with 0-90-ohm range application. Summit has several at the site shown below.
