spot on....I'm assuming you would remove the mechanical pump altogether and make up a blanking plate to cover the hole?
I strongly doubt the "original equipment" ever worked properly in the systems that relied on the bleed-back-to-the-tank pressure regulation, standard on the r20 and fuego and probably others. The Fedtro transformed my r20, better economy, power and smoother running. There's nothing fancy about an electric pump, it's just a more efficient and rather inexpensive alternative - it's all about peace of mind.......repairing and or maintaining the original equipment and keep it running as it was intended
