-Not to hi-jack this thread but keep it going
I just swapped a 454 in place of a 250 in a 1978 swb and it has the return line but the truck does not -so naturally I plugged the extra line so I could do a burn out or 10
Now the problem is I take it for a hot lap and it pulls HARD thru the first 2 gears of the TH400 but soon after it hits drive it dies
Then I get to pull over and look like a douche and crank it over until it blows smoke and fires back up and runs ok
Could the pump be flooding the carb? -I frantically pump the gas to get it started so I don't if it's too much fuel or not enough
Basically I'm just trying to get info on how the return side being plugged could effect the pressure under these conditions
I am going to try using fresh gas in the other tank and see if the pickup might be the problem as the truck sat for a while before I got it
I will probably buy an in/out 2 port a NAPA for $30 and try it too
Just asking so we can all sort this variable out of the equation
