I reckon the majority of electric fuel pumps down under are vehicle fuel pumps that you can buy in any auto shop. My gyro has done approx 1500 hours on its auto fuel pump...
Chris, would you know which one on that page you linked is a good fuel pump for a 912ULS?GyrOZprey;n910030 said:Good document to compare...
( :yo: kudos to Cammie for her help in finding the information I needed!) :first:
chart shows the various specs for the different pierburg pumps ...seems a smart idea to stick to the same pt # ... :der:
7.21440.78.0 .... hard to find for sale online in US ... got one on order from Europe! $131 incl S&H ....(OE) ..... will take a couple of weeks!
The GOOD news ... on systematically checking stuff before pulling the fuel system apart ...I found a loose wire behind the panel ... when i tickled the wires ...pump fired up & showed normal pressure!! eace: ... now to chase down the wiring glitch!!
Thanks Vance !! I was going to go diving for the fuel pressures. I'm also a big proponent of fuel filters anyway.Vance;n1137124 said:A small caution Carlos; the Bing carburetors won’t take a lot of fuel pressure and are very sensitive to dirt.
My recollection is a maximum of four pounds. I don’t have the pressure numbers but it should be easy to find for your particular model Bing.
A good fuel filter properly plumbed is important for a 912 and more so for a 914.
