Putting a walbro in a 98 return fuel system. OK i whipped the fuel pump assembly out of the tank. The whole assembly seems to be riveted together. I assume you have to drill the rivet at the bottom then remove the bottom plate to get the fuel pump out. Anyone done this ? Next the inlet on the top of the walbro has a bulge right on the end....does the stockie.... i didn't take it apart, i just had a look to see what i had in the tank. Also the pick up opening on the bottom is much bigger than the stock.... i'm thinking that i'm gonna have to file the bottom plate to allow the sock to fit on. Anyone who has fitted a walbro to a return style.. any tips would be greatfully accepted. I searched btw... FST non return was all i found ....G.
