Im at my wits end with this diesel
. I left an anchorage in the glades and the engine
died. i sailed back to tampa and pulled into a slip towing with my 4 hp dinghy
. (solo). That was two months ago. I found the fuel
pipe between the filter housing and injection pump had rusted out and was leaking. My first thought was a quick fix. I took the lines off (ones running from filter to injection pump) cut the ends off leaving enough to clamp hose to. before reattaching to the injection pump i ran a half gallon of diesel
thru in case I had rubber from inserting fittings on the hose. I then bled a copious excessive amount of fuel
locking screw and the air vent on the top of the governor. It has an electric pump
inline so its just a matter of opening bleeding points and letting it flow. I was catching the diesel and ran at least a quart through each point. it would then start instantly, run for exactly 5 seconds then die. Wait for about 10 seconds and do the same thing. I bled, over and over till I figured maybe rust had gotten into the injection pump.
Phase two. I traded a bimini
build for a perkins
4.107 in parts
. The two lines i needed were shot but the injector lines were in much better shape than mine so... I replaced the injection pump, injection lines, and ran 1/4" copper lines with compression
fittings in place of the rubber hoses. This seemed to work well. Again I ran copious fuel thru to flush lines before connecting to pump. Did the same bleeding thing running a bunch thru the same points except one additional point i picked up in the injection pump manual which says to bleed at the blocked off passage
at the filter housing. After I figured out the stop lever runs backward from the one I had I have good fuel squirting out of the lines while cranking. After final bleeding, It cranks right up, runs for 5 seconds then dies AAAAARGH!!!!!!!!
One thing I noticed which i dont know if is normal is... I get a strong flow out of head
locking screw, it will shoot 6" or so out of the vent screw i get steady drips but nowhere near the flow of the head locking screw. Normal??? Didnt think too much of it after looking at the pump diagram and seeing possible flow restrictions from metering valve and small passages.
Anybody can shed some light here? Im tracking down a diesel mechanic
who needed canvas
work and gonna try to work out some kind of barter for his services. He charges $85 hr and I cant afford many of those (hrs)
Thanks for any replies.
I should add, racor
filter, replaced. lines gone over from end to end and less than 2 yrs old. Fuel flows unimpeded to injector pump
. pumps quart in no time.
