primer bulb keeps going flat

[phatmanmike]

1976 1150merc 115hp inline 6<br />1986 bonito 16' center console<br /><br />i am using a red , plastic style gas tank, with a EVINRUDE fitting on the tank, connected to the grey fuel hose, then to the bulb, then to an inline , clear filter, then strait to the fuel pump, no more connections at the motor.<br /><br />the bulb and line are new, but keep going flat.<br /><br />i disconnected the EVINRUDE style connector at the tank and ran the line straight into the tank and problem solved.<br /><br />do these motors really use THAT MUCH fuel that it squashes the bulb flat?<br /><br />motor is fairly new to me. thanks

I would think you need to vent your tank.

Tank not vented properly.<br /><br />Restriction in pickup tube in or at point of entry.

sorry, i GUESS i DIDNT MENTION THIS BEFORE....<br /><br /> TANK IS VENTED! i even removed the entire screw on cap that the vent is on, and same thing. with cap removed, tank has a 2 inch opening as a vent and still squashes the bulb....removed pickup tube and checked screen, found nothing.<br /><br />does anybody that has one of these motors ...do they really suck THAT MUCH fuel

No...they don't suck that much fuel. Something is wrong. What I don't know, but that isn't supposed to happen.

Try another bulb. It's not unusual to get a bad one.

Re: primer bulb keeps going flat

yes, i bought some brass fittings from hardware store and now it goes DIRECTLY into the tank, with no lil "quick disconnect" fittings/.<br /><br />directky bolted from tank to fuelpump. also lessens the chance of "sucking air" and blowing motor<br /><br />thanks guys
