Duke Posted July 15, 2008 Report Share Posted July 15, 2008 I am purchasing stuff for my KA swap and I am wondering what fuel pumps and regulators people are running for Mikuni's/Webers? I have 44mm Mikuni's on a KA24de...so what should I spend my hard earned money on? Quote Link to comment
69FJWagon Posted July 15, 2008 Report Share Posted July 15, 2008 Duke, I have a carter low pressure high volume pump and a used reg. off of Troys racecar prolly a Holly reg. set at ~ 3-5 psi range Clayton Quote Link to comment
banzai510(hainz) Posted July 15, 2008 Report Share Posted July 15, 2008 My yellow car has a old mallory 140(low pressure) and a dial type Puralator regulator Previos owner. The carter is a good pump!!!!!!!!!! Quote Link to comment
ggzilla Posted July 15, 2008 Report Share Posted July 15, 2008 Mikunis take 3.5 pounds pressure ... same as stock Datsun pump. No regulator needed if the pump is under 5 pounds max. Quote Link to comment
five10freak Posted July 15, 2008 Report Share Posted July 15, 2008 Duke, I have a carter low pressure high volume pump and a used reg. off of Troys racecar prolly a Holly reg. set at ~ 3-5 psi range Clayton that is the standard equipment to use on side drafts, works like a charm set the fuel pressure to 3 psi have fun parts available at summitracing carter pump,# P4070-$71.95 Holley FPR, # HLY-12-804 - $27.95 Quote Link to comment
240ADAM Posted July 16, 2008 Report Share Posted July 16, 2008 I used a stock fuel pump with no regulator for my triple webbers on my Z and it worked just fine. If you go pay for a electric pump and regulator you are just wasting money. Quote Link to comment
Icehouse Posted July 16, 2008 Report Share Posted July 16, 2008 Just a question for the carb dudes.. Why can't you just run the return line?? wouldn't that keep the pressure low? Just though.... Quote Link to comment
hang_510 Posted July 16, 2008 Report Share Posted July 16, 2008 ^ ive seen it. im thinking about doing this on the goon as the next powerplant will be FI. Quote Link to comment
hang_510 Posted July 16, 2008 Report Share Posted July 16, 2008 If you go pay for a electric pump and regulator you are just wasting money. if they were free youd do it? it does remove some friction/drag off the cam :mellow: Quote Link to comment
Duke Posted July 16, 2008 Author Report Share Posted July 16, 2008 Thanks for the reply's guys. Looks like the Carter is the way to go. I used a stock fuel pump with no regulator for my triple webbers on my Z and it worked just fine. If you go pay for a electric pump and regulator you are just wasting money. I'm putting the carbs on a KA24de. It doesn't have provisions for a mechanical fuel pump. Quote Link to comment
ggzilla Posted July 18, 2008 Report Share Posted July 18, 2008 Why can't you just run the return line?? wouldn't that keep the pressure low?Pressure would be zero... unless you have some kind of regulator on it. The nice thing about electric fuel pump is it starts right away even after sitting for a couple of weeks. With a mechanical pump, you have to crank, crank, crank the engine to fill the fuel bowl. Plus it makes it easy to pump off a quart of gasoline (say to refill the lawn mower) should you need it. Mikuni PHH information 1 Quote Link to comment

ggzilla Posted October 25, 2012 Report Share Posted October 25, 2012 It is still relevant isn't it? No need to create a new post when one already exists. Quote Link to comment
