Hello - I need to put a fuel pressure regulator in my 1985 DL 240 series b230f and someone told me I have to prime the pump after I install it. Exactly how do I do that? Do I just hook up a wire from my psoitive battery terminal to the fuse? My fuse box cover says my "in tank fuel pump" is #4 and "main fuel pump" is #6. Do I connect a wire to both of them? When I take the old fuel pressure regulator off will fuel be constantly running out of the fuel rail or does it stop after a short time - what can I use to maybe plug it up for awhile?
Thanks for your help - Ron
