87 BII Fuel Issues
87 BII Fuel Issues
Had recently rebuilt my 87 BII 2.9L . New Heads, gaskets, Distributor, wires, plugs, etc,.. I had a fuel leak at the filter and replaced the connection and fixed that problem. Now i'm getting a slight roughness and a knock in the fuel tank like the sending unit is rattling sometimes. I've replace the rear tank pump/Sending unit. Replaced the rail fuel pump and the fuel pressure regulator.Timing is spot on. Getting 30psi running out of the new pump and up to 37 off. Starts right up. I've put a lot of work in and just can't live with this slight roughness. This thing should be doing wheelies. At a loss for what can be causing this slight issue. Anyone have any thoughts? Can't imagine the relay half working? Ive pushed that cut of switch a few times on the passenger side but doesn't do anything. Does that rear filter on the return cause any problems ever?
