Got another few questions for you. Here is the situation. I have a catamaran
with 2 x Yanmar
27 hp motors. They have intermittently struggled with priming issues and shut down with air in the fuel
. I know air in the fuel
is a monster to track down sometimes. The fuel tank
is located far forward of the engines and is much higher up than they are. I pulled the fuel tank
for some other related work
. I noticed the fuel lines are hardened. I'm assuming air is getting in somewhere.
In the short term, I'm considering two options (I don't have time right now to replumb the fuel lines all the way).
1) I install day tanks
at the engines and pump
fuel from the main tank into the day tanks
2) I just try to install a fuel pump
at the main tank and hope the "pushing fuel" instead of letting the engines "suck fuel" resolves the issues.
Thoughts on best approach?
Also other related questions....
1) Which fuel pump
should I use? I'm assuming something that is continuously pumping and low PSI like a walbro FRA series, but totally unsure of that. I don't know if the walbro pump
will allow fuel to flow when powered off. Can someone school
me in pumps?
2) How or where does one find the parts
needed to make a diesel
day tank? I've read other threads where people added fittings onto tanks, but I'm not sure what all work
is involved here.
