Good grief, $99 , and it's for the Eber BN4 used on other ACVW's, I wonder if fuel delivery per stroke's the same.

UPDATE - Just checked the specs, and the T4's BA4 pump should produce 22cc/200 pump strokes, and the BN4's pump is spec'ed at 13cc/200 strokes. So, unless the BN4 pump can be modified/adjusted up to almost double its normal output, it can't be used to replace the BA4 pump. Boy, that Typ 181 heater is puny...

Do you guys know if this fuel pump for a BA6 could be adjusted to work with BA4 heater?

Is capasity should be about the same as the BA4 pump has. I've understood that the BA4 and BA6 heaters were cousins anyway, so maybe the pump is the same or just about the same?

Those specs are not capacities....they are adjustment specs. These pumps are adjustable. If memory serves the pump on my 412 can be adjusted from about 10cc to 30cc's range. Ray

Sorry, poor english day... The BA6 pump works in a range of 18,4 to 21,7 cc/200 strokes and the BA4 pump 11.8 to 12.5 cc/200 strokes. So do you think the BA6 pump could be edjusted to pump as little as 11 to 13 cc of fuel per 200 strokes? And do they work with the same principle? So eventually, could i use the BA6 pump with the BA4 heater?

From memory...I have had it down to as low at 10cc. But...I also remember that at low cc;s....its not reliable or accurate. It seemed that when you overly restrict it, it had problems keeping even flow. It could have ust been that pump. It can put out well over 20cc quite well though.
I will have to dig into my notebooks to see what my last adjustment was like. Its been over 10 years. Ray
