In-tank fuel pump testing

[Mike Goble]

I put the 633csi in-tank pump in my Bavaria to test it today and it worked very well. The length is almost the same as the stock pickup/sender so it went all the way to the bottom of the tank. When I powered it up it pumped a little over 1.5 gallons of fuel in two minutes, and when I pinched the line off the pressure maxed out at 2.5 psi. This should run a couple of Webers quite adequately.

If the same as the coupe tank, how did you handle the fuel guage? Is it built into the sending/pump unit?

It's like this one - the sender is right next to the pump. You have to remove the sender to remove or install the pump.
