    TBI Fuel Pump Wiring

    I am converting a 78 GMC K15 with gen 1 sbc/th350 to TBI from a 1991 Chevy 1500 donor truck. I upgraded the fuel system (tank/pump/sending unit) with new aftermarket 1987 V10 parts. The pigtail plug on the new fuel pump has two wires, grey and purple. The TBI harness has a grey wire from the...

    12 Bolt, 6 Lug disc brake options

    Hello - new to the forum. In searching this and other forums I see many options available for both aftermarket and DIY disc conversions for 5 and 8 lug axles. I have found a few aftermarket kits for the 12 bolt, 6 lug axles. Some of the 6 lug kits require either turning down the axle flange...

    TBI Intake Swap

    Any recommended tuners? I don't see any in the preferred vendors. I found Harris Performance online. Anyone worked with them?

    TBI Intake Swap

    Simple is good. No emissions here so I will tune out un-needed extras.

    TBI Conversion Fuel Tank Options

    No salt spreader on this truck. Very few, if any of the private plowers in this neck of the woods use salt. That bladder is a neat idea, but like you inferred it is cost prohibitive for this project. I was able to find a Dorman (576-336) tank for the 87 that says it is baffled. If I go this...

    TBI Conversion Fuel Tank Options

    Thanks for the suggestion. I will check out the 87 tank as I'm not interested in taking a chance on a used tank. Is the 87 tank baffled? I have read issues with the older square body tanks causing fuel starvation issues because of the lack of baffles. Are the pumps noted above plug and play...

    TBI Conversion Fuel Tank Options

    Hello - new to the forum. Thanks for the great resource! I have a 78 K15 with a 350 that my son and I are in the process of converting to TBI. We found a 1991 Chevy donor truck and have begun stripping everything we need. My question is on fuel tanks. I want to convert to an updated TBI...
