Installing Oil Pressure Sending Unit on your LS swap? LOOK HERE!

[kSStamp0182]

found this nice little part today that replaces the oil cooler block off plate. just ordered it. i am running a '91 Suburban sending unit with 1/4 NPT so it will need to be drilled & tapped.

it is the one farthest to the left.

i started with the one far right, but it was difficult to drill straight and tap, & now i have a seeping leak from it. it was also too close to the manifold IMO. and sticks straight out. this is much cleaner looking.
