Forget above windshield washer suggestion. I did some further research and think the following is closer to your requirement. I do not know how to post a link but Google Amazon.com and enter in Amazon search "12v car washer pump kit' . They claim 135 or more psi and 80 to 100 watts and 1 to 5...

Why not try an automotive windshield washer pump? They force a pretty good flow thru the washer jets so they might have enough pressure. Certainly suitable for water.

I am surprised no one has mentioned "idle bar" glo plugs that we used in the early days of throttled/exhaust restriced glo engines, when fuel/air mixtures were not well regulated, and engines riched out at idle. The concept was a platinum? bar across the bottom of the plug to retain combustion...
