    Default need enderle birdcatcher injection help

    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

    that's the prob, it did this in the shovelnose too, and he using the same lines he had in it i looked up the line size and it's supposed to be 3/4 i.d., no less. i called and told him to go get a hyd 3/4 i.d. line made up and we'd run the boat again saturday. bet it cures it.

    there's not alot of mechanical injection gurus around during the day my homey fiat already pm'd everything i could wanna know, he's helped me wrap my mind around this stuff and i think i've got a pretty damn good handle on mechanicl injection now, its alot more simple than tuning a dominator, and that's the truth.

    won't know till we're both runnin 100% and both have some good gas to run. he'll get nitrous too if i do

    Did you get the issues straightened out?
    -12 from tank to pump inlet
    -10 to barrel valve
    Gas or alcohol?
    Wags
    Tank height can make starting hard also. These pumps don't suck all that well. If the tank is pump height, an engine will usually run on the pump as soon as it fires. If the tank is on the floor or in a tunnel, it will take more priming.

    Thats a simple one you are starving the motor and roasting the pump!!! get a real supply line and call me in the morning,It needs a big supply line just like it needs bypasses. M

    Here comes the add on!!! that big a motor would require atleast a #12 inlet and #8 for the feeds and bypasses to the tank. M

    we've gotten 3/4 line on the tank to pump now and 1/2 to the hat. we used 6an on the high speed bypass and idle bypass back to the tank at least 2 1/2 ft away from the supply bung on the bottom rear. we used a loop line on the shutoff valve bypass and its returning to the pump inlet.


    so does this look alil better???????? gonna try it out tommorrow
