That sounds like my best option right now without going external.
If I can put the. 381 in place of the 90 pump I would just ad the sending unit to the old hanger?
Does that make sense?
I'm in Las Vegas by the way but for emissions I only need the tailpipe probe and a good gas cap. No obdii on a 90 so they won't have to check the computer when I smog it. Which is coming up soon. Forgot about that.
ok hold on. your truck is a 90 but your putting a 95 dash... im assuming this means DASHBOARD. but your putting an 05 gauge cluster in. is this correct? I think I'm following now... lol.

well in that case you won't need the old style sending unit at all since it sends the signal in a different manner. in 96, that's when obd2 started and gm changed to the newer style. so your EASIEST option would be to find a tank from a 96 to 98 truck. the duallies kept the body style until 2000 iirc. any of those should have the newer style sending unit and the tank should fit right in there. not sure if the duallies had bigger tanks tho.... and that would be it. fuel pump AND sender solved. but a tank isn't exactly cheap.

or you somehow remove the float wiper of the old unit and put the new wiper/float on. this would be the cheapest but would require some serious engineering! lol. and you would still need to swap the pump to the newer style also.

OR like I mentioned, do like I did and make a bracket for the new float and install it inside somewhere. you could use the wires from the old one since u don't need it. that way you don't have to add wires to the tank and try to seal it. that was a pain in the ass...

other than that, I can't think of any other way...
