for about a year now my fuel gauge has been broken, it goes up and down , shows empty when my tank is full, then shows full. i finally had enough and im ready to fix it. on our trucks does the sending unit and fuel pump come together? also if it doesnt can i just get a sending unit? my pumps had been making a high piotch whining noise at times, could i replace it with a walbro? and what it involved in doing this with an aftermarket pump?

 

yes u could replace with walbro 255lph thats what im doing saturday!
You need a new sending unit too i believe!


Heres the PN for summit of the model you need
SUM-250103

see my post for posted instructions


the summit fuel pump is made by walbro and is a good bit cheaper than holley and b&k which are made by walbro as well

 

So we will need this mustang fuel pump, fuel sending unit and is that it?
Im goin with a turbo, and my fuel pump has 6 years and 150k miles on it. So this sounds like what i need to be doin pretty soon. anybody got a link or PN for the sending unit?

 

if your fuel guage is working correctly then you do not need a sending unit, just the pump!


yes, this pump and follow these instructions and that is it
