In fact, all the Walbro pumps show to be good value. Due to their high price, the two Bosch fuel pumps are not as good a value."

Did they scope the pumps to check pump RPM?
Junk cheap pumps (like those Airtex POS things aka "comeback in a box" have looser tolerances on the pump, and the motor spins a lot faster. Good pumps spin down around 3000-4000rpm. Some of those Airtex things spin at close to 8000rpm when new. Think that wears the brushes and commutator down faster?

Obviously you look on-line.. If it has a nice, expensive looking web-site then it has to be good. And if a lot of people say it's popular, then it has to be good. All knowledge is found on-line Grant. People on line know everything and if they don't then real knowledge is just a few keystrokes away. It's only by looking online for example that we learned that "left foot braking is indispensable" for a guy who had done 2 events, that a $15,000 dog-box was a "must" fort a guy with 4 events who wasn't faster than other guys with stock box and a 2.5, that nuc-u-lar mushroom clouds would be the next thing you'd see if a person with less than some years experience shifted a turbo 2wd rally car into gear, and what the next big thing to save rally is going to be. And that "Heat Fence" is soooper bitchin and your dumb insert will be zapped up pretty soon...No such a shame you haven't listened when i've said to send the tubes up for a re-call to improve them...Oh well, you're too cool.

I use the arrangement Mercedes used in all the V-8 and V-12 cars from the late '80s to the late '90s.
Two pumps on a bracket with a pulse dampener and fuel filter on a mounting bracket that I'd purchase from Aurora Auto Wrecking in Seattle Hmmmm (206)524-8700? for a hundred bucks. Quiet, dependable and will fuel your sickest power fantasy. Works for me. JohnLane Overkill is consistently more fun |

Sweet! I've spent everyday at the shop, which has been about 16-20 hours per week typically, for the past six months working on customer cars. I really wanna get some work done on the Merkur so I can race it again this coming spring. Get me that insert so I can get the car rollable and get some stuff done that requires mobility (pressure washing, painting, and a day on the lift) then I'll put it on jack stands, pull the inserts and send you the tubes by the end of the year!!!

This is why I need to visit here more often. Ladies and gentlemen my sides have left the building.

Looks like the stock vw fuel accumulator is leaking, a lot. So now is probably a good time to go dual pumps in the spare tire well, and do a host of other updates. I have a few extra Volvo/VW CIS pumps that I'll be using to push the fuel.
My question is: Fuel accumulator necessary or just plumb the in-tank feed directly into the high pressure pumps? Gracias. |
