High speed fuel delivery problem

[TPD211]

Hi all,<br /><br />I know this has been a topic but I'll post my problem.<br />My 1993 88 SPL is cutting out at 1/2 to wot. <br />I have done the following:<br />Checked fuel lines<br />Reseated and tightened fuel lines<br />Replaced 1 cracked fuel line<br />Checked vent on main tank<br />Checked and cleaned filter at the fuel pump<br />I ran a can of the OMC carb cleaner thru the primer valve following the directions. <br /><br />I attached my new spare 6 gallon external tank as was suggested, it did the same thing.<br />So I assume the problem is isolated to the fuel pump or carbs.<br /><br />I ran it WOT with the primer manually engaged, it ran like a raped ape. <br /><br />Suggestions? Am I on the right track?<br /><br />Thanks

I think so, TPD211. <br /><br />Before going into the fuel pump, though, I would try spraying premix into each carb to see if it is only one of them failing to deliver enough fuel, or both. <br /><br />If your power comes on when adding fuel to one carb, but not the other, overhaul your carbs.<br /><br />If power comes on when adding fuel to either, go for the fuel pump.<br /><br />Good luck.

Thanks JB, <br />I didnt think of spraying premix into the carbs, I'll try it tomorrow.
