My 500 dollar Fuel Pump Doesn't Suck

... But it's suppose to. There in lies the rub.

Sorry about yesterdays vague cry for help.. I'm pretty much at my wits end with the bus, because it has cost me so much time and money in the last 2 months that it is now threatening to derail the project. I cannot handle another break down without breaking down myself as was demonstrated on Sunday when I thought everything was working great and headed off down the road to Austin... I got a whole 1/4 mile before slowing to a stop. When I tried to start it back up it wouldn't.. because I was freaking out so much that I'd left it in Drive instead of putting it in neutral. (it only starts in neutral).. Gordon came out with the Bio Liberty tractor to tow me off the road (that's when I realized it was still in drive).

The FASS pump installed made the bus top out at 25mph. Fuel starvation. This pump is built specifically for WVO, Bio Diesel and of course diesel yet they designed it to Push more than pull (suck) even though Most Veggie conversions are configured to suck the fuel through the filters instead of push it through. ANYway, since the crappy 100 dollar pumps I've blown up along the way were able to suck it through (for a limited time); the FASS pump was expected to suck at least as well only last considerably longer. That line of thinking was far too rational for reality. I replaced the fuel filters to solved the problem (wasted money). Then we thought it was the fuel lines being too weak to handle the pressure of this monster pump and replaced them (wasted money). I was about to put the damn thing up for sale and in my anger .. reconnected the (truly piece of shit) fuel pump that brought me to Slidell .. Guess what? Everything worked great. I was back up to my normal 57mph in 1 minute flat. But this one won't pull veggie and is 45psi too low even for diesel; which makes it too scary to leave Slidell on.

So what does this mean? I think it means we have to redo the FASS pump to push through the filters which means adding another 3 port valve and small screen filter prior to the pump.. mo money, mo time, mo uncertainty... At this point I think I would have been better off just paying for fucking diesel.

Thanks to those who called. I got a mechanic to "look" at it and gave me things to try which eliminated some of the variables leading to reconnecting the old pump just see if the bus was fucked or not. He'll help with remodeling the conversion later this week...

disclosure: the pump itself was not 500, the pump, the wasted filters and wasted hose was well over 500... another week of my life... priceless.
