Fuel Line Replacement

Hi All,

I'm a life long "gas" guy and the diesel thing is new to me. I like it, it's just new. I have a couple fuel lines that are just as hard and ready to snap or crack as any I have ever seen (one is actually starting to weep around the clamps). The lines are a return line from the electric pump (Universal 5424) and the feed line from the water separator. Will I have to go through the bleeding process?

Re: Fuel Line Replacement

Yes!!! Probably more than once. I like the corrosion resistant coated steel lines wherever flex is not required. The strongest most durable you can find elsewhere and watch them.

Zen is a matter of recognizing reality.

Re: Fuel Line Replacement

yes, as you change the lines you would introduce air in the system, so you would need to bleed it. Usually it's not too hard, just unscrew a bolt a little and crank the engine until you see fuel coming out. You would need to do it on the filter bolt and on injector too. Look at your engine manual how to do it properly.

No, No, NO, you just don't need to crack injectors on Universal engines.

Find your engine at Marine Diesel Engines and Engine Parts - Universal, Volvo, Westerbeke, Yanmar, MASE and you can read the bleeding instructions.

Your engine and our M25 series are very similar. This may help: Bleeding 101 Bleeding M25 Series Engines 101- A Summary of Links for You
