Fuel filters

[mstpierre]

I have a 1992 Evinrude 115 OB on my boat I recently purchased.   The owner has installed a fuel/water seperator, RACOR, that has a screw on filter and a clear bowl with a drain plug on the bottom.  I have replaced the filter element on this filter so that is fine.  My question is this:

Betweeen the screw in filter and the engine is an inline fuel filter as well.  Do I need this on here.  I am fine with replacing it with a new one as they are all so cheap.  What I am concerned with is how many filters the fuel can pass through before it filters too much and does not allow enough through or creates to much restriction.  I just don't want to rob fuel or create too much restriction with redundant fuel filters.  

So... leave it or replace with a solid fuel line and eliminate inline filter?

As always, thanks for all the advise.

I too run the inline filter between the seperator and the engine. Never had a problem. I change out the inline filter every six months or so.

Definatly keep it on. I have just gone through alot of trouble because i had no inline fuel filter. The fuel/water serperator does not filter out particles in the fuel. If you do not have a fuel filter it goes straight to your fuel pump, and will cause major trouble. In my case some fuel had become coagulated and the particles broke up and started getting in my fuel pump clogging it up. I had to rebuild the fuell pump(which turns out is pretty easy to do) and put a filter in between the seperator and fuel pump. After i did that i have not had 1 problem.

BTW. i have a fuel/water seperator, inline fuel filter before the fuel pump, and another inline filter between the fuel pump and carberator on a 2000 90hp mercury and it runs like a champ.

Ok, thanks.  Are these filters standard by the nipple size or ...?  How do I know which inline filter to get and where to get it.

The filter i installed came from Autozone. It cost about $10 has a cleanable filter and is clear so you can see if it is clogged. It also comes with different size nipples to accomidate any size hose from 1/4 to 3/8

Here is the one i have

I use the same filter on my 1967 Evinrude Starflite 80 hp. I do not currently have a water seperator filter on my fuel line, but would like to. I have heard conflicting reports that these filters will filter out the two stroke oil from the fuel. Some advice from users of these filters would be greatly appreciated . Thanks.     Happy fishing.

The extra filter probably wont hurt.

I use a sierra water/filter separator. It works great and it does filter the gas. It uses a 10 micron filter. No problems or complaints.

The Sierra 10 micron filter is the one that I am interested in. West Marine sells it. I've had a water in the fuel issue once before (expensive repair bill) so I'd like to install one of these filters as long as it won't create a problem with my 2 stroke oil.     Happy fishing.
