we took out my uncle's blown injected 547 tx-20 yesterday and we're still having injection issues. i think it doesn't have enough fuel supply volume, he used smaller lines than recommended in the enderle instructions he got from good vibrations. it's a bitch to start, you've gotta prime the shit outta it, then once it's cranked up, you gotta stay popping the primer to keep it runnin till it begins the surge. once it's surging, it does fine till we hit wot, then it'd hook ass for 3seconds, go lean and die. i think it just doesn't have big enough fuel supply lines and the high speed bypass is returnin more than the small supply lines can keep up with.
what line sizes should the tank to 80a and 80a to meter block be? he's got 1/2 tank to pump line on it now, and the line from the pump to the meter block is even smaller. i think this is the issue but needed some other opinions. he had all stainless made up and i'm trying to get him to go get some cheap bigger 1's made up today to see if it solves the fuel starvation issue at wot.
appreciate any help fellas, i'm no mechanical injection guru, just learning the stuff myself and havig fun with it
