Fuel pump help!!
 

Okay so my blazer has been having some slightly hard starts and some issues with fuel. Put a pressure guage on it and got a good 60 psi while pump runs but drops as soon as pump shuts off. While running has a solid 55 psi at idle. The fuel guage is always pegged out and i replaced the ground but this the fault is really in the plug on sending unit but im wanting to replace the whole thing just to be safe. Ive been told dont get anything besides delphi or ac delco but im having a tough time finding them anywhere. I have a delphi pump at local parts store but cant find a delphi sending unit. All i can find is spectra. Is the spectra any good?
. thanks

Normally my go to place for things like this but they also only carried spectra.
