Tinaja, NM on the way to Raton, NM for the night and then on to Pueblo, CO tomorrow.
OK, I was wrong, it was not the fuel pump. I hate to start off talking about bad stuff but it has been consuming my thoughts for most of three days. We drove from just North of Santa Fe to Raton, NM today. Not very far but we wanted to be able to rest for a night before getting to the rally and once we get there we usually don’t rest much at all. The scenery was mostly gorgeous – Georgia O’Keefe was not wrong to spend her life painting this scenery.
Yesterday was our second day of the trip. I thought that I had the problem solved by swapping the fuel pump the night before but that was not the case. Everything ran great until our first gas station stop after which we had the problem again – unable to run at low speeds. Somehow we managed to make it to Santa Fe where I did swap out the big fuel filter near the electric fuel pump. It did not fix the problem so we limped our way to a campground just North of Santa Fe to spend the night. Thinking about what could be happening and not believing for a second that the fuel vapor bypass mod had anything to do with our problem. I decided to try ignition parts – module and coil – first and then, if that didn’t fix the problem, I would clamp the rubber portion of the hose in the bypass plumbing and thereby totally eliminate any effect it could have.
This could be a long story but I will simply say that the problem happened again in a gas station right after filling up. I immediately opened the engine hatch and clamped the hose and the problem went away completely. No doubt about it. Now the question is why is this happening? Carl S. suggested the possibility of a flow restrictor being needed since it is possible that there is not enough fuel flow to handle the engine and the bypass. Carl has the same mod done with different fittings which may have more restriction and he also uses the standard mechanical fuel pump which might have more flow capacity than my electric. More later as I find it.
