Erm...what sending unit?

 

fuel pump assembly....

 

the oil sending unit is located right below the oil filter and he wants to know if you can use a series 4 sending unit in a series 5 or vice versa. for those who still dont know what we are talking about its the unit that sends the oil pressure rateing to the oil pressure gauge.

i too wonder if you can interchange them. can anybody illustrate us with this?

 

Get your stories straight.

The oil pressure sending unit is the same for 86-91.
Fuel level sender is listed as S4/S5 specific and since I've never swapped them, I don't know what the difference might be.

 

well they look completely different s4 unit is bigger. thats why we are asking

 

What looks different...the oil pressure sender or the fuel level?

And...you guys' info shows you as being on opposite sides of the country, yet you keep talking as though you're collaborating in this thread.
How does that work?
