I have pulled the fuel pump off my 1985 Johnson 70-HP and want to replace it with a fuel pump [which does not include automatic oil mixing with the gasoline]. My original fuel pump started leaking. Now I need a new pump. A [Sierra-brand fuel pump part number 18-7353] was recommended, but [the author believes that this part is for a] 20-HP or 30-HP engine, which doesn't seem right. [Seeks] any suggestion [for a replacement fuel pump for a 1985 Johnson 70-HP outboard engine].

Napa carries Sierra parts so contact them for a 1983 pump which would be non VRO.

[This author says he] bought a [Sierra-brand] fuel pump. I installed it and now my engine won't even start. At least before it ran with the [original] fuel pump. [Again there is a solicitation for] any ideas [for a replacement fuel pump for a 1985 Johnson 70-HP engine].

Visit the website SHOP.EVINRUDE.COM. Use their on-line parts catalogue to locate your 1985 Johnson 70-HP engine. You should be able to find a replacement part number from the illustrated assembly drawing. There may be several models shown, so find the one with the non-automatic oil-gasoline mixing fuel pump. Once you have the OEM part number you can confirm with your local Evinrude or Johnson dealer that the fuel pump will be suitable, and the dealer can sell it to you (or order it for you). Or, you can place an order on-line.

Jim is correct: I Like to use for my parts. I like the on line diagrams so I can find my part. I also think OMC makes a kit to redo the fuel pump, you may not have to purchase the hole thing...
