i have a problem with no fuel being supplied to the engine and my fuel guage is staying on E even with fuel in it. I figured it was my fuel sending unit also. Im trying to figure out if thats what it is.

Junk yard maybe

my truck had the same issue you dont need the whole part its simple get the vulcan draw straw kit worked perfect and less than 75.00 the metal lines your have that is cracked pulls out of the top of the pump from the rubber grommet the vulcan draw straw is an aluminum block that goes in its place that has tube that goes into the bottom of th pump you will have to gut the pump and drill some holes you will have to get rubber fuel line to go from factory lines to the draw straw very easy to install easy to understand directions

I found a place that will sell you the parts .. the unit or rebuild your sender and they are at a much better price than getting a new one .. if they rebuilt it .. they make sure nothing ever goes wrong buy putting a coating on any steel and they do not use any plastic and they first get rid of the problem parts bad or good right off and then make sure the rest is all good or they replace it .. even if it shows a small crack under a scope so I called them and they explained all they do .. and if I send them a new fuel pump like a airdog rapture with the full install kit .. they hook up all the fillings and lines to your measurements and when you install you sensor .. the pump is ready also to just plug in is real busy .. it may take 7 days total to get it all fixed and in your hand
just get hold of Tri Star radiator ... they are in Seneca Falls, NY 13148

I replaced mine with a VULCAN PERFORMANCE - DRAW STRAW I ('94-'04) 44.99
