Re:  Ingen Technologies, Inc.
         Your call of March 1, 2007
         Your File No. 0-28704

Dear Mr. Hult,

Thank you for your call this morning regarding the letter filed on EDGAR
yesterday (re: Ingen Technologies, Inc.'s Form 8-K/A filed on February 28,
2007). As mentioned, the scan done on your letter of February 22nd dropped out
the sentence preceding the 3 bullet points (starting at the bottom of page 2)
and I was not aware that the company needed to make those representations. I
apologize for any inconvenience.

Please consider this letter as a supplement to my letter on behalf of the
company as filed on EDGAR yesterday.

I am authorized by Ingen Technologies, Inc., as General Counsel, to acknowledge
on behalf of the company that:

         -        The company is responsible for the adequacy and accuracy of
                  the filings.

         -        Staff comments or changes to disclosure in response to staff
                  comments in the filing reviewed by the staff do not foreclose
                  the Commission from taking any action with respect to the
                  filing; and

         -        The company may not assert staff comments as a defense in any
                  proceeding initiated by the Commission or any person under the
                  federal securities laws of the United States.

Please contact me directly should you have any questions or further concerns
regarding this filing.

Thank you.

Respectfully,

Ingen Technologies, Inc.
