Been reading quite a bit of posts from here that date back to 05' and have some great input.
Re-doing my dual carb fuel line routing on my 914/4 2.0. Tank, pre filter, low pressure pump,.....then should it go fpr, gauge, t-fitting, carbs, no return? Its a 1 in 2 out FPR. And a inline FPG. Thanks 914World |

there are benefits of a return line
thats how the factory did it and it does keep the fuel cooler and thus adds power here is a thread with diagrams its been discussed so many times that I sound like a broken record: http://www.914world.com/bbs2/index.php?sho...p;#entry1470608 |

I used:
Fuel cell (tank), filter #1, holley (red) pump, pressure regulator (all in front trunk), fuel pressure gauge (in engine bay) @ splitter, see-thru fuel filter at each carb, feed to each carb, No return. Plan on removing the cheap see-thu filters@carbs before racing (but they really help with startup when you leave the car sitting for a few weeks without firing up - you can see when the bowls are full) |
