Fuel issues

[Ricko1966]

My 85 has a 96’ vortec 350 with no provision for mechanical pump. I don’t really trust external electric pumps and was thinking of replacing the short block to go back to a mechanical. thats Not looking like such a good idea now. Mechanicals used to be reliable, guess that changed too.

Use a tbi pump in the tank and a bypass regulator. You will potentially cause bigger reliability issues going to an old block,because you will lose your roller cam.

I would never change a block to get a mechanical fuel pump. There are many external electric pumps that will work just fine. If worries throw a spare in the glove box?
