Fuel Filter Issues

[Jurgen]

Hi All,
Have a problem with a blocked fuel filter, a little complicated as it's the filter at the end of the fuel line in the tank?
Apparently there is a gauze filter at the end of the fuel line.
Has anyone had a similar problem and if so how easy was it to remove the filter from the fuel tank?
As allways
Many thanks

Is that a bayliner in your avatar ?


I have had several Bayliner tanks to bits.

There wasnt a filter at the pick up of any of the ones I have seen.

The pipe could be blocked however, just attach a dinghy foot pump to the outlet pipe and pump away until it clears.

NB note I said foot pump,, might not be a good idea to use an electric pump.

Hi Daka,

Yes it is a Bayliner, will try the footpump, not sure what else the problem could be, cant get over 3000rpm WOT. Really hope it's not a compression problem !

Just a guess but it more likely that a paper filter is reducing the flow to your engine.
Pick up pipes do not normally have any mesh at the bottom but I have known boats with gauze mesh in the lift pump and in union of fuel pick up pipe and fuel pipe proper on top of tank.
My engine has got a primary water/dirt filter in line plus 2 x smaller paper filters to prevent muck getting to injection pump and injectors.

what engine?
under load same as in neutral?

Are you convinced that it is definitely fuel starvation that is preventing your engine revving higher?

Revs freely when in neutral

5.7 V8

Changed the main filter, ME Looe sugested the fuel pick up, otherwise may be lack of compression!

Could you fix an oil extraction pump before the lift pump and check delivery rate or obstuction

I may be making a big assumption but is this petrol?

Most of the responses you are getting at the moment are related to diesel fuel systems....

Try the elbow on the top of the tank, the one on , my friend's boat had a small mesh in the elbow itself, this had blocked.

Petrol

another way would be to get a outboard fuel tank and connect that directly to the engine seatrial the boat and see what revs you pull then. if max revs are achieved then you have a fuel problem if not then you have a different issue. stuff to think about

1. is the hull/drive clean

2. correct propellor?

check the obvious before you start ripping the boat to bits........

yep - step one......

hi jurgan had same problem with my bayliner v8 where the fuel line connects into the carburetter there is a small filter behind the nut, does not take much to reduce the flow of fuel.
