Hi guys, a litle of the topic but still very relavent to most of you guys running large single needing adaquite fuel supply.

basicaly ive tested 545whp with stock fuel lines in an fc and twin stock fuel regs using only 2 walbro intank pumps.

pls check the link ive already posted in the 'second generation forum' it has all the testing info and conclusions all explained.
cheers!

Good to know, did you T the two pumps in the tank or did you use the stock send and charcoal filter hard lines up to the motor?

 

I was going to use the charcoal filter line but there only about 3mm diameter unlike the huge ones found on the fd3s, So instead ive just had them T together in the tank.
