the stock fuel pump will be ok for about 100 bhp, ovr this and you'll need an electric fuel pump, filter, regulator.

Stock mechanical pump and line fed the 2180cc in my last buggy just fine. No fuel starvation.

I went to a 5/16 line in my new buggy, just because I had to replace the stock hard line anyway. I believe stock pump and fuel line are good enough for engines bigger than mine.

Haven't dyno'd it yet, but it does make good power.

Stock fuel line was able to support 135 HP in one of my old cars using a red faucet pump. That's got to be close to the limit though.

When I had my 2110 I used the stock pump to make around 140 hp. No fuel problems at all.
Bergs proved you don't need anything more until you are deep into the 12s.

Hello All, I am running a stock: fuel pump, hard line to my duel 44's(2054cc) approx 140hp, and I do beleive I am running out of fuel delivery around 6,900rpms
I will be switching to the CB performance rotary pump and or maybe the Holley Blue with the Holley regulator, a pressure guage mounted in line right after the "T" at the regulator and some nice AN braded hard lines with those cool anodized Webber fuel line adapters.

I will run the new larger line through the Passenger side Heater channel, abandoning the stock line.

Where do you find steel gas line? (a local autoparts store?
was it hard to fish through the heater channel
How big of a hole was drilled?
