Has some body use a in fuel pump as a water pump for a liquid-air ic set up? I'm just wundering since it will last longer than a regular pump and may be pump faster.

 

I'd just stick to a marine bilge pump. I've got a Jabsco one. It's built like a brick shithouse so I doubt it'll burn out anytime soon. Plus, you don't want it to pump too fast.

 

The seals in a fuel pump may or may not be rated to pump water. That is an idea, though.

Fuel pumps are easy/cheap enough that it might be worth trying.

if they seal fuel, they will seal water. seals usually get eat up by fuel, but I'm talking about a inline fuel pump. I just think they are more durable. If you put a voltage regulator you can make it variable speed.

 

Many fuel pumps are of "wet" construction and use the fuel as a coolant in and around the motor. They are also pressure equalized inside to provide a long life. (therefore the seals are different than in a water pump.) I would not recommend attempting to use it to pump water--I don't think it would last.

Try johnson pump. These are smaller than the jabsco and I have had good results with them. I don't have the model # off hand, but if you want it PM me and I will find it for you.

 

My dad rigged up my old stock FD fuel pump to use in the water injection in his turbo mini cooper, It works awesome...!

 

The diaphram pumps I use for my water injection kits are ideal for what you are looking for. They pump 1 gallon per minute and run from 60 - 100 psi depending on what model. You can view them at www.coolingmist.com about midway down.

These are designed as a demand pump so they have instant response and are designed to take a beating.
