1986 v6 fuel pump replacement

[Jeff Rodgers]

Was hoping to swap gas tanks from the 88 to the 86. The 88 is a short bed so maybe that’s why they won’t interchange. Pulled the fuel pump assembly from the 86. Is coated with really black crud. This truck sat for 7 years. Trying to purchase new fuel pump and all I’m getting is a mechanical one shown.  Anyone have a part number for the in tank fuel pump assembly?

Wait. The 86 2.8L had a FI sending unit and not just a sending unit for the gauge? Weird. But yes a short bed 18 gallon tank will not fit in a long bed without some sort of modifications. Course it might fit but only two straps are needed to hold it. 
 

But the 2.8L is a mechanical pump from the factory. Unless someone rigged an FI sending unit to work.

You are absolutely right. I’m not on site. My son had taken it out. Hopefully his 88 sending unit will  

swap as they seem hard to get. Thanks!

Ok hopefully the tank in your long bed is a 23.5 gallon tank, if so the sending units will swap over. If not, youll get some inaccurate readings if its a 16 gallon.
