This buy it now listing is for one (1) Spacer for the fuel vacuum pump on the M38 and M38A1 military jeeps.  This is the spacer that makes installation possible for the fuel pump.  Without it, you are up the creek without a paddle. These are NOS, in original boxes.  I have 3 different boxes these come in, so no guarantees as to which box you will receive.  Small flat rate shipping to the US.
