    Default 98 K2500 fuel pump question.

    I have a 98 Suburban K2500 4X4 with 454.

    I'm on my second in tank fuel pump and I'm really not looking forward to the hassle and expense of changing it out.

    I was wondering if I would have to remove the in tank fuel pump if I decided to go with an external pump.

    the old pump will cause the new external pump to run harder and may die sooner than needed. why not cut an access hole in the bed area above the tank and put a removable trap door over the hole. this way open the access panel dissconect the fuel lines and level wires and the lock ring then lift out the pump unit and swap as needed. i got a Bosh "Gold" unit and not issues for almost a year and 20000 miles so far......mike

    The old jeep Wagoner’s had that trap door made right in, and I have done that exact trap door repair on many other vehicles. It saves a lot of headaches.

    Just cut the hole with an air chisel, with the pannel cutting tool, looks like three fingers, makes a nice cut and doesn’t create any sparks. Now you will have to make the trap door a little larger than the hole to seal it nicely.
