So I got an Airtek pump installed this afternoon and after some troubleshooting I was able to get the pump running. However, the pump is not sucking fuel and I can't imagine it would need to be primed???
The tank was dry so I added 2 gallons which I can now see in the tunnel fuel line (yes I have the old lines in the tunnel still).
The pump is located on the firewall not in the original location. With the firewall mounting the inlet is very close to the tunnel so routing the lines to the inlet requires a couple 90 deg sweeps up to the inlet with the filter in between.
The only reason I can think of for the pump not sucking would be:
1) Faulty pump
2) Leak somewhere in-between the pump and where the line exits the tunnel
3) Bad fuel filter
4) Maybe my 90 deg sweeps to the pump are to restricting??? Perhaps I should run a length of pipe around the pump that sweeps into the pump inlet???

I know a few others here have used this pump which seems to work very well.

Anything you can offer would be helpful!


You may have your pump mounted to high,try adding more fuel to the tank and if it primes its to high.
These pumps are good @ pushing fuel not sucking it,the 914 is one of the few FI cars I have worked that has the pump mounted so far away from the tank,did Porsche really move it to the front because of vapour lock .
My Carter pump is mounted on the front alloy crossmember under the tank,not ideal but the best for suction from the tank.

Many thanks!

Thanks.
My thought too. The car is not currently on the road but I like to start it once a week to keep the fluids moving, etc. I don't like to keep more gas than necessary but I will add a little more this time around and see if I can get it to prime. If I ever run out of gas I wonder if I will be able to get it started???
