Since I have a box of relays I have changed out for MAF got to noticing all the different part numbers. Think the factory one or one in it when I bought it wasTRW 14103304. Have a Sorensen MR 44, DWD MR44 that I have used. Ones in it now are the grey colored ones made in India. Number is come off the top. In searching for new relays I see the same part numbers come up but only list that relay for fuel pump . The ones listed with same part number for it cost about half what they ask for MAF relays. Are some of these relays on the car interchangeable other than the two MAF burn off relays? Just curious why fuel pump relay is so such cheaper. Is it because it fits other cars. Does going on a Corvette automatically make it more expensive?
