Fuel pump suggestions for 44 IDF's

[Sandeep]

Hi all,

I was reading this link on suggestions on how to choose a fuel pump ... here . They suggest for a 200hp engine, you need 100 lbs of fuel per hour which works out to 63 litres / hr or about 17 gal / hr.

Does this sound right ? I'm looking for a pump now and thought I would share this. What do you folks suggest ?

Thanks,

Sandeep

Umm ... OK ... mathematic calculations aside (?), 44 IDF's can use a Walbro fuel pump just fine; lasts long time. With in-line filter.

Really.

I used a Holley Blue with Blue regulator on my 1776 with 44's and worked fine also. Good for 100 gal/hr full flow. My friend now has it on his 2.0L.

Thanks for the suggestions

I'll look more closely at the Walbro.

Sandeep, CB makes a very nice rotary pump that doesn't make alot of noise like some of the cheap pumps. You want a pressure regulator to keep the PSI at 2.5-3psi at the carbs for Webers or Dells. Any more PSI and you will have flooding problems.

Thanks Ken,

That pump was also on my list.

I agree with ken. A rotary pump does not pulsate like a facet valve pump. (facet valve pumps are the small, cheap, square shaped ones) I've always run Dellorto carbs, which are kinda temperamental (I don't think I spelled that right) to changes in fuel pressure and volume. I've used facet valve, and rotary pumps with Dellorto DRLA's and DHLA's and the rotary pump didn't cause full throttle lean-out like a facet valve pump does.
Competition would require additional fuel volume, certanly more than could be supplied by any pump available at your local parts store, so therefore if you want no compromise in fuel delivery, get a high volume rotary pump and most importantly, get a GOOD regulator that can go down to 2.5 PSI.
