This is on a stock 74 1.8 L-jet.
I just relocated the pump to the front and installed the SS lines. I'm not getting fuel to the engine, plugs are dry. I followed a post Darling made to connect the 3 port pump to the tank/ss lines. Pump turns on with key in the on position and AFM plate pressed open. Do I need to prime the system? I didn't think that was necessary since it is a return style fuel system. My only thought is a pinched fuel line under the tank after I set it in. Just wanted to see if I'm missing anything before I try to drain 5 gal of gas from under the car to lift the tank out. Dan |

You need to cycle the pump at least a dozen times (turn the key on & off) to get fuel in the lines & up to pressure.

You need to cycle the pump at least a dozen times (turn the key on & off) to get fuel in the lines & up to pressure. Not on a 1.8 with L-jet, Mark. The Cap'n In DJet when you turn the key to the run position it activates the pump for 1-3 seconds. So, on a dry system (new lines, injectors etc) I typically will turn the key on and off 5 times then start the car...its fills up pretty fast. On LJet, I am never really confident that the fuel pump runs. It does not run when you turn the key to the run position (by design) I think its supposed to run when you crank the starter, but that makes no sense...most cars shut everything down except coil and starter for that cranking process. The pump runs when the flapper door opens on the AFM and the key is in the run position. The only way I have had any luck on a dry system is to turn the key on and open the flapper door with my finger until I hear the pump change tone...then I know there is fuel pressure in the whole system. Then I plug everything back in place and start the car...once pressurized the first time it holds forever as far as I can tell...we have parked my sons car for months at a time and it starts right up, no priming needed. Djet seems to loose its prime after a few days, so my habit (right or wrong) is to turn the key two times then start it... My Djet has no leaks, but it does like it when I turn the key twice...it starts right on the first crank...otherwise I crank for a while and it starts, so its fuel related. Rich |
