Fuel pump alternative use

No, it's not for a chargecooler :) It's for a experimental washer fluid heater system with a simple heat exchanger in one of the coolant pipes. It needs a pump, and have tried 2 pumps (gears) but these died quite fast. The first one had a burnt motor, the other had knackered gears after a week and in turn caused the motor to fry. I'm now considering to put the heater in the washer bottle itself, as pumps are not easy to source, and gears pumps are not suitable for this application.

Why not follow the usual route of running either an extended length of washer hose, or brake hose that is spliced into the washer hose, coiled round the radiator top hose?

Has been known to stop pipes freezing, or two thaw them in minutes. Far simpler than a heat exchanger.

I already have the exchanger, made of standard copper pipes you can buy at any general hardware store. Works great, as long as the pumps works :)

Have you considered truck or bus Washer motor/pump which apparently have a longer throw and have to maintain pressure because of the size of the windscreen?

I've seen them used in DIY water injection systems.

Renault 19 or clio 16v have an secondary electric water pump fitted that'd to the job.
