Bleeding an in line fuel filter...

simonmcnamara · 01 May 2007, 22:31

Hello all,
Any help on this question on bleeding fuel filters would be much appreciated…
I have just fitted an inline fuel filter (one of those small see through jobs..) into the fuel line supplying the Johnson 4 stroke 115 on our rib (need to do this as have also installed a fuel flow sensor in the line and it needed a filter upstream).

The question I have is that there remains some air in the filter body that won’t go away. The engine runs fine, but I have not run it at high power settings as it’s out of the water at present. Any ideas or advice on how to get rid of the air, or indeed if it is even a problem??

Thank you..

The air shouldn't be a problem if there's no obvious method of bleeding it under the cowling.

no problem, those filters always remain with inner air, not to worry to you. personally I would have installed an effective more filter

Yep! if you light a match it will go away

Thanks Nos4r2, isla and Aidan for your answers. Took the boat out this weekend and indeed the air is not a problem and it does not go away! Useful to know and useful to have your advice before heading out – thanks again.

Isla, there is already a fixed water separating filter in the system but it was not practical to put the flow meter downstream of this so opted to put a extra filter upstream of the flow meter.

Thanks again
