air bubbles in fuel line what do i do??

[scorpien boats]

my nitro vee is running great...............all exept for one problem after its running and stuff it seems like air gets into the fuel line and the engine kinda struggles................................and sometimes stalls because of it

what can i do to keep consistant fuel running through ???

[Baja-Destroyer]

prime it to get the fule running through that may clear out the air

Air in the fuel Lines - oh nooooooo. Time to trash the boat and get a new one. LOL Just Joking.


I'm betting because of all the waves you and Baja run in. The fuel gets sloshed around alot, Therefore air gets in the line.


not sure if you can stop it from happening in 3 foot waves.

any one have any ideas?

[scorpien boats]

i mean when its on a plane

[scorpien boats]

lol 3 foot waves

i would never run my nitro vee in that
i ran my bladerunner in it but if that flips it doesnet matter because no water gets inside...........tonight i ran my vee in about 5inch waves

Could it be a pin hole in the fuel line or that the line in the fuel tank isn't long enough to sit on the bottom?

Just some thoughts.

[scorpien boats]

thats what i was thinking a pin hole...........but then wouldent there be a fuel spill?

i think it just gets swooshed around alot like brushless said

maby i should keep the tank full all the time

[BrushlessHawaii]

try and make your fuel line as short as it can be. so less room for problems

[HOSE MAN]

TRY ADDING A HOPPER TANK INTO THE SYSTEM THAT WAY IT ALWAYS PULLING FROM A FULL TANK ,IT WORKED ON MY TUNNEL:D

yea thats wat a hopper's for, use one.
without the hopper somtimes it sucks foam which makes bubbles....

air in the fuel line to the extent it is a problem means your sucking air from somewhere.

replace your fuel lines.... you might have a pin hole and no you likely wont find it. check that the fuel line connections are all snug. empty your tank, and place it in some water.... blow through the fuel tube while plugging the other end to pressureize it..... look for bubbles in the water. if you get bubbles fix them

hope that helps

installing a hopper tank is a good idea just for stoping air bubles, the fuel foaming up never seen that happen...if your pick up tube is made of brass inside of the tank, it may have a hole in it, or even a small crack.....fuel line may have a pin hole, the best way to check this is to take it off and streach it, a small hole will become large looking. if all else, just replace the entire fuel line and tank,
