I want to replace the E Qjet on my blazer with an aftermarket carb and electric fuel pump, just concerned about the solonoids messing with the computer , and the return lines for the fuel pump. how is this going to affect it?

86 k5 carb help

I would advise against the electric pump (unless you have a reason better than power savings or reliability, which are both not true of the electric), and you will need to replace/rebuild your distributor with a non-CCC model. Essentially new carb and distributor are all you'd need to get rid of CCC.
Realize that this is illegal (both CA and Federal) and as I understand CA law, would make your vehicle essentially impossible to resell.

If the carb seems to work, you MIGHT be able to sell it to someone in CA, as the replacements for those things are apparently quite costly, IF you can find them.

Yeah, dont go with an electric fuel pump. My 85 K5 had a stock 5.7 with a q-Jet carb when I first got it. When that engine went out I replaced it with an barely used 89 TBI 5.7 and considered keeping it TBI (it came with the ECM) which meant I was most likely going to need an electronic fuel pump.
Instead, I used an Edelbrock Performance 650 cfm carb, replaced the intake with an Edelbrock Air Gap, and stuck with my old mechanical fuel pump. I believe that my Blazer is running better, faster and stonger than it ever did.
Although, I did have to get a new gas cap because now I was getting LOTS of sucking from the old one. . . still havent figured why it does/did that but if it aint broke dont fix it! Good luck!
