Debris in Fuel-pump

[The Force power]

A day after I had changed my worn-out primer squeeze-bulb; the carbs. were starving for fuel.
I removed the fuel-pump & opened it up for inspection, there I found pieces of material that I can only assume are remnants of the check-valve of the primer squeeze-bulb.

Another lesson learned; When replacing a (worn-out) squeeze-bulb inspect the fuel-pump

That is the deteriorated lining from the inside of the cheap fuel lines. Replace all of the lines as well

^+1.........what he said......

make sure your new fuel line is A1-15 rated like this moeller http://www.moellermarine.com/moelle...niversal-38-i-d-x-80-hose-a1-15-034387-10lpa/

Thanks guys for the replies!

I (coming out of the diesel world with little knowledge about fuel-rated hoses) replaced all the hoses (less then) two years ago with these Dayco fuel line.So these are already deteriorating??
I can't find any numbers corresponding with the ratings recommended

:facepalm:Just found my question;
The Dayco Fuel Line Hose meets SAE J30R7 requirements and meets the fuel permeation requirements of SAE J1527 Type 2, Class B specifications. This hose specification does not meet any EPA or California Resources Board emissions requirements and should be used only on vehicles exempt from such emission regulations.

Note: Not suitable for gasoline/oil mixed fuels, alcohol blended fuels, or bio-diesel fuel. NOT suitable for fuel injection systems. For use on vehicles not subject to CARB or EPA requirements.

Looks like it can't be used for anything in the modern world.

Thank you for making me aware :thumb:

White plastic?????
More than likely not from a BLACK hose???
The hose dissolves and leaves a black film in the
filter.

The best way to stop this (big pieces)is install a water separating filter
down by the tank.

The pump shows it's using a Mercury style pump and there
might be a filter between the carb and the pump.
Unfortunately it's not gonna catch the plastic but will get the
very small pieces that make it to the pump.

Now look for the source of the white plastic??

Good morning Jerry,

I did install a (inline) fuel-filter between the pump & carbs. So yeah... it not helping to keep the pump clean.

Unfortunately I threw out the bulb, because I could of do an autopsy on the bulb

Any idea? it was initial soft like cured silicone and dried and feel like cut off toenails. lol

What would be the best fuel line to use then? A plastic lined grey fuel line? I recently replaced my fuel line with a black fuel injected type line and am wondering if this is a future issue for me? I had a grey lined fuel line and it seemed to be breaking down, but filter and screen seemed clean.
edit: Just re-read posts and was A1-15 is recommended.

It seems as though I need to add a fuel-water separator to my set-up. Are there any guidelines for type or size I might need for a '89 125hp? Thanks for your thoughts!

on a boat fuel system, A1-15 rated fuel line

Neoprene (dyed black) is not fuel resistant.

The fuel line is constructed with a neoprene cover and nitrile (naturally yellow) tube for use with leaded, unleaded gasoline and diesel fuel.

The hose with the liner: The problem was
the hose and the liner would separate and
the liner would twist and collapse shutting
the fuel off..

Gearhard. The 85 in fresh water can use any
water separating filter(walmart)
Salt water use a good Racor that's outboard
rated and that won't delaminate in salt water.
