Bummer man, you'll get it fixed. Double check the ground wire and connection, etc. And double check the relay, try bypassing the relay with a jumper before you drop the tank...

I actually wired the fuel pump into the holley without a relay. It was on the minimum requirements for amps. I'm wondering if that is why it burnt up?
And now that I think about it, I pulled the fuel pump fuse from the cab wiring to test not the holley side.
I believe you just used the relay that powers the injectors, and it can also power the fuel pump if it is small enough. It doesn't actually power the fuel pump through the ECU, there is still an external relay within the Holley harness I am pretty sure. Search the harness, you should find it.
The injectors have 12V power all the time the ignition is on, the ECU triggers each injector through the ground PWM.

Yes sir, can't believe I didn't think to check that. What's funny is my buddys sniper in moab blew the fuse and I knew right where it was.
Fuel pump dead, fuses are good even cut the wire near the pump and it was good.
Thinking about doing a cheap inline pump for the time being I want to redo the fuel lines and tank. How hard would that pump be working going through a intake pump?

It might be okay for casual driving but I would think it'd be a flow restriction. Only one way to find out. But really, it's better to just do it once, do it right. You'll end up saving time and money on the long run.
I agree, just need it to work for one day and I honestly don't care if I'm paying more for it.
Now this gives me the excuse to redo the fuel system and put a different gas tank in, just don't have the time to pull it off for Fridays event, a 2500 vehicle expected squarebody show...
Made it to the show had a great time.
Did a little trans tuning, need to read up on it but the factory Holley to me is junk or it's not playing nice with the Sonnax parts.
Any reason to go with this over a blazer tank?

Also I'm trying not to cut into the bed floor, any tips to make this fill right?

So that tank bolts to the lower flange of the frame with the brackets that are welded on?
If yes, that sounds like a future broken aluminum tank due to vibration and truck frame flex.
And it's difficult to make a tank fill nicely without working on the floor some to make room for the filler to be raised up enough for decent fall and a straight shot into the neck with the nozzle. At least that's what I have found.
And your post about the transmission tuning is really vague, but I have no idea what to do anyway, so.

Here's a fuel pump by Holley for saddle tanks that's finally back in stock. Just throwing options out there for you.

I didn't realize that it mounted that way, I believe you are correct.
The shift points are off, I don't like how sometimes I have to let up or give it more to shift, it kind of hangs in gears.
That is a nice tank, trying to get away from a saddle tank though for more capacity and weight over the rear.Here's a fuel pump by Holley for saddle tanks that's finally back in stock. Just throwing options out there for you.

factory Holley carb ?? splain pls
I’d stay with a blazer tank. If you’re careful when you lay it out and install it, you can still get the tank out pretty easy to do a pump. I’d still do a hatch.
If not, use AN lines and build your slack so you can tighten the fittings on the tank before you lift it. Make sure you can find the sender before you go all out

I'm leaning this way, I want to do hard lines and some soft to pull the tank. Hatch Is a must but im concerned about the filler.
Holley terminator x
What about it?
Don't want to cut the bed any, also not very good at body work
