[urq] UrQ Fuel delivery fix challenge

[Jack Walker]

Ben,

Totally agreed, is indeed a little over kill and expensive.

Just had seen this and thought wow! 

 

So, Ben

An in tank pump.

"Some day I may remove the tank and weld in a new bottom - carefully pumping
nitrogen or other inert gas into a tank that has been washed of fuel."
Explain this a little further, would you place a pump into the tank and
another in line after the tank?

Nice - massive overkill.  Would definitely prevent cavitation and certainly
deliver enough fuel.  It does kind of fall out of the desired  price range
and fitment criteria.

 

Keep in mind two things:

 

1. problem is really the bottleneck of the small tube coming out of the fuel
tank.  This is where the fuel capacitor works despite simplicity.  It sits
directly under the fuel outlet and acts as a "buffer" or "capacitor" holding
enough extra fuel so there is no problem with cavitation.  Also the return
line is teed in keeping pressure balanced.

 

2.  Where ya gonna fit this contraption.  I mean that nicely as it is a good
piece of work.  I wanted to keep my car as close to looking stock, retaining
full trunk capacity and nothing out of the ordinary showing.  This setup
would be great for racing and for someone who just wants to add a fuel cell
and mount in a low spot in the trunk and doesn't care about where to put the
luggage.

 

The best solution - even better than my "fuel capacitor"  would be an in
tank pump.

Some day I may remove the tank and weld in a new bottom - carefully pumping
nitrogen or other inert gas into a tank that has been washed of fuel.

I was just on the S2 Forum

There's a guy in I think Finland that's making these;

Sort of sounds like the dual pump and container.

Looks like it could fit into a UrQ spare tire well, or anywhere else someone
would like to put it...he wants $1400 for one all plug and play!

Sort of expensive, but I'm going to guess this is pretty much what everyone
is talking about??
