    H.O. fuel pump?

    OK, finnally going to get the H.O. intake put on the car, and want to swap the fuel pump to an H.O. pump (in tank) anyone know which one I need? The car has a H.O. motor in that I put in a few years ago... been running it on a stock intake / TB / fuel pump... (Orange injectors) Finnally getting the chance to put the intake and TB I got from Scott.... The car runs ok, but I know the new intake will REALLY wake it up. I need to put a new sending unit in for the fuel gauge, and i'm going to do that when we swap the fuel pump... just don't know which one to get for the car... any suggestions? I want to keep it in tank... Not external....

    Since you have a 90/91 a mustang pump is a direct replacement.

      Is the fitting the same on the Mustang pump? (The one connecting to the fuel line?) And I guess the fuel sock will work the same? Just wondering... not sure about the differences in tank design between the two....

      I just don't want to get the pump out, and find out it won't fit....

        Its a clamp inside the tank. Its just a piece of hose from the pump to the hanger plate and it clamps in place. You'd use the sock from your stock pump. If the diameter is not the same, then you can just use a hose clamp to fix it in place. I know the 80s models used a fatter pump than the Mustang. I have no idea what they did on the 90s models.

          For any '89 owners that may be reading....

          I recently replaced my 89 fuel pump and considered using the 89 mustang pump. O'Reilly's had pressure and flow data on both pumps (at the store, not on line) and they said the stock merc pump was actually rated for slightly higher flow and the same pressure. So even though I've done the HO conversion I stuck with the stock replacement pump.

              Replacement pumps are rated much higher then our stock box pumps. See 86VickyLX for more detail. The factory box fuel pump is borderline good enough for a stock HO swap. gt40p's or anything else would really be pushing the stock 20+ year old lopo pumps.

              90/91 pumps are the new smaller style just like Mustang pumps. 89 and down are the larger style, and Mustang pumps need some slight mods to work.
