         FOR VALUE RECEIVED, each of the undersigned, STANADYNE CORPORATION, a
corporation organized under the laws of the State of Delaware ("Stanadyne") and
PRECISION ENGINE PRODUCTS CORP., a corporation organized under the laws of the
State of Delaware ("Precision"; and together with Stanadyne, collectively, the
"Borrowers"), HEREBY PROMISE TO PAY, jointly and severally, to the order of GMAC
COMMERCIAL FINANCE LLC , a Delaware limited liability company ("Swing Line
Lender"), at the offices of GMAC COMMERCIAL FINANCE LLC, as collateral agent and
administrative agent ("Agent"), at 461 Fifth Avenue, 21st Floor, New York, New
York 10017, or at such other place in the United States of America as Agent may
from time to time designate, in lawful money of the United States of America and
in immediately available funds, the amount of TWO MILLION DOLLARS AND
($2,000,000) or, if less, the aggregate unpaid amount of all Swingline Loans
made to the undersigned under the "Loan Agreement" (as hereinafter defined). All
capitalized terms used but not otherwise defined herein have the meanings given
to them in the Loan Agreement.

         This Swing Line Note is issued pursuant to that certain Loan and
Security Agreement dated as of the date hereof by and among Agent, the lenders
from time to time party thereto ("Lenders"), Borrowers, and Stanadyne Automotive
Holding Corp. (as the same now exists or may hereafter be amended, restated,
renewed, replaced, substituted, supplemented, extended, or otherwise modified,
the "Loan Agreement") and is entitled to the benefit and security of the Loan
Agreement and Other Documents. Reference is hereby made to the Loan Agreement
for a statement of all of the terms and conditions under which the Loans
evidenced hereby are made and are to be repaid. The date and amount of each
Swingline Loan made by Swing Line Lender to Borrowers, the rate of interest
applicable thereto and each payment made on account of the principal thereof,
shall be recorded by Agent on its books; provided that the failure of Agent to
make any such recordation shall not affect the obligations of Borrowers to make
a payment when due of any amount owing under the Loan Agreement or this Swing
Line Note in respect of the Swingline Loans made by Swing Line Lender to
Borrowers.

         The principal amount of the indebtedness evidenced hereby shall be
payable in the amounts and on the dates specified in the Loan Agreement, the
terms of which are hereby incorporated herein by reference. Interest thereon
shall be paid until such principal amount is paid in full at such interest rates
and at such times, and pursuant to such calculations, as are specified in the
Loan Agreement.

         If any payment on this Swing Line Note becomes due and payable on a day
other than a Business Day, the maturity thereof shall be extended to the next
succeeding Business Day and, with respect to payments of principal, interest
thereon shall be payable at the then applicable rate during such extension.

         Upon and after the occurrence of any Event of Default, this Swing Line
Note may, as provided in the Loan Agreement, and without demand, notice or legal
process of any kind, except as provided in the Loan Agreement, be declared, and
immediately shall become, due and payable.

         Time is of the essence of this Swing Line Note. Demand, presentment,
protest and notice of nonpayment and protest are hereby waived by Borrowers,
except as provided in the Loan Agreement.
