         RE:      INGEN TECHNOLOGIES, INC.
                  REGISTRATION STATEMENT ON FORM SB-2
                  FILED ON DECEMBER 15, 2006
                  REGISTRATION NO. 333-139421
                  REQUEST FOR WITHDRAWAL

Ladies and Gentlemen:

Pursuant to Rule 477 promulgated under the Securities Act of 1933, Ingen
Technologies, Inc. (the "Company") hereby applies for the withdrawal of its
registration statement on Form SB-2, File No. 333-139421, which was filed on
December 15, 2006 (the "Registration Statement").

Such withdrawal is requested, as the Company is uncertain of the basis for
determining that the transaction is appropriately characterized as an offering
to be made by or on behalf of persons other than the registrant, consistent with
Rule 415(a)(1)(i). As a result, the Company determined that it should withdraw
the SB-2.

No sales of any of the Company's securities have been completed and the
Registration Statement has not been declared effective by the Commission.
However, the Company may undertake a private offering in the future in reliance
on Securities Act Rule 155(c).

Should you have any comments please contact the Company's legal counsel, Richard
I. Anslow, Esq. at (732) 409-1212.

Very truly yours,

INGEN TECHNOLOGIES, INC.
