I think my fuel pump is on its way out and isnt pumping as much as it should especially at high rpms. So i bought a fuel pres. guage from jegs and i got the guage and it doesnt have any fittings to go with it?!? The fitting on the back of the guage is a 1/8 NPT male fitting. I cant think of or find any fitting to just go right into the schrader valve on the fuel rail. Do u need to remove the schrader valve and plug the 1/8 NPT female reducer fitting right into the fuel rail or what? IM very confused and i have called jegs and summit and they have absolutely no idea what the hell to do. Any suggestions would be awesome. thanks in advance. -Nick
