Dear Mr. Kreucher: 

Enclosed is the information you requested regarding test 

results which we discussed at our meeting on April 13 but were 

not included in the "Test Data Results for Onboard Control 

System" table which was made available at the MVMA meeting on 

April 20. 

In response to your request for additional data on testing 

which has been done since the April 13 briefing, we are still 

in the process of completing these tests and documenting 

results. As soon as this test plan is complete, the results 

and data will be made available to you. 

I have also included a revised version of the table which 

was distributed to MVMA. 

If you have any further questions, please feel free to 

contact me. 

Sincerely, 

4yo~~ j

Conditions Causing Voided Tests 

The following conditions resulted in voided tests. The 

actual data and results on these tests were not generally 

compiled, as visual observation of the FID response was used to 

determine whether or not adequate control was achieved. Many 

of the tests were not completed as once the lack of or 

inadequacy of control was observed, the test was terminated. 

Inadequate Liquid Seal 

Date Comment 

3-31 3 GPM Fill/rate 

3-31 """ 5 " 

3-30 3 " 

3-30 4 " 

These test were run with the stock fillneck. Upon adding 

a 1.050" ID restriction to the tube, control was achieved. 

Multiple initial nozzle kick-off 

Date Comment 

4-5 10 GPM 

3-24 10 GPM 

At high fillrates with a sensitive nozzle like the OPW 

ll-A, nozzle positioning is important in order to achieve good 

fill quality. In these tests the nozzle '"was incorrectly 

inserted in the 'fillnec: causing multiple kick-offs upon start 

of fuel flow. It should be noted that the stock (unmodified) 

tank also performed this way upon start of flow at high fill 

rates. Once the nozzle was inserted properly, this problem was 

eliminated. 

Leak in Tank 

Date Comment 

4-7 High emissions were a 

result of a leak in the 

weld area where the 

valve is located. 

A leak- check was done, the leak was sealed, and all 

subsequent tests passed.
