I've tried every type of fluid, and if you want to clean parts to get oil off, there is only one that works well. White spirit. Dries without a residue, removes oil, but not paint. However, flammable, and will probably dissolve your plastic pump.
I just bought a fuel pump and plumbed it in, and it works fine.
I dont think that white spirit on your skin will improve your life, so good gloves are important.
