    I know that there are some of you out there who have coverted from carb to tbi. What fuel pump did you use, fuel return line, and did you have to baffle your tank? All help will be greatly apperciated, Thanks. /forums/images/graemlins/ears.gif

    i but TBI in my truck and used a fuel pump for a '90 chev. truck. went right in my s-10 tank. If you want to use and aftermarket electric one that will work too. just make sure it has 15psi.

    I have 2 converted trucks, one has the baffled tank and factory intank pump. One has an inline pump on its third pump.
    The last 2 inlines were Holly ones, they both failed on warranty and I had absolutley terrible warranty service on both.

    I now have a fuel pump from Howell (I believe its made by Walbro). Both trucks run fine. If you are running steep terain without a baffled tank just make sure your tank is above 1/2 full.

    Most baffled tanks I have looked in have had broken baffles anyway, so I personally don't think spending the extra cash for a baffled tank is necessary, and the intank fuel pumps are a much bigger pain to replace (even if you do cut an access plate in your bed)- although they are about 50 bucks a pop cheaper.

    My supply and return are both regular (non special high pressure) rubber fuel line (with long stock steel runs). They both have been in service for many miles.

    I have seen plans for a surge type reservoir that uses a low pressure pump to fill it, from which the TBI inline pump takes a suction from. If you were climbing verticle faces a lot that might be a good idea.
