Fuel pressure

[-spiro-]

The last couple of trips i have had a problem with having to prime the fuel bulb everytime i want to move. I have replaced the hose with new stuff, the fuel priming bulb and also the water filter.
A couple of things that i have found is
that i can blow back down the thank breathers easy
the petrol don't flow that fast though the petrol priming bulb when i unhook it from seperator{ very bubly}and prime it into a bucket.
if i put a bolt into the end of the hose to block the hole after the priming bulb, it still loses pressure in a hour or so.
there is no crap in the external hull fuel breathers.

I was woundering if i might need a new 0ring on my fuel cap, as i think i have tried everthing else.
Any answer to this problem???????

All new fuel lines and bulb??
Had a motor I had to prime everytime till I put new diaphrams in the fuel pumps...
Think they were 8 bucks to replace each..

just a guess,, but have a look at the fuel pick in your tank.
some of these are just a piece of hose with a filter on the bottom. this hose may be cracked therefore sucking air as well as the fuel. this will cause the loss of pressure in the fuel line.

had similar prob replaced old omc fuel lines with softer ruber ones think they were sucking air at the clamps hoga
