The BE Pressure 98210300 oil dipstick (also cataloged as General Pump / Interpump 98.2103.00) is the small part that keeps a pressure washer pump honest. Pressure washer pumps fail from oil problems far more often than from wear, and this filler-cap dipstick is how operators catch low oil, milky oil, or abnormally high oil consumption before a crankcase runs dry. It is a direct replacement for the 3/8-inch threaded dipstick cap used on General Pump EZ and TT series pumps, and it also fits 44, 51, 59, 63, FE 51, and T series pumps.
Use Cases
Pressure washing contractors keep a spare 98210300 in the truck because dipstick caps crack, vent-holes clog, and threads strip from repeated oil checks. Fleet and rental shops replace them at every pump oil service so the level markings stay legible. It is also the standard fix when a pump starts weeping oil at the filler cap: a worn cap seal lets crankcase oil mist out under vibration, and a fresh dipstick cap stops it.

Frequently Asked Questions
Which pumps does the 98210300 dipstick fit?
It fits General Pump and Interpump models including the EZ series, TT series, 44, 51, 59, 63, FE 51, and T series pumps. It replaces part number 98.2103.00 and uses a 3/8-inch thread.
How do I check the oil level with this dipstick?
Set the pressure washer on level ground, unscrew the dipstick, wipe it clean, reinsert it without threading it in, and read the level against the marks. Oil should sit between the marks and look clear amber, not milky.
Why is my pump losing oil at the filler cap?
A cracked or worn dipstick cap is the most common cause. Crankcase vibration mists oil past a bad seal. Replacing the cap with a new 98210300 usually stops the seepage.
Is this the same as the BE Pressure branded dipstick?
Yes. BE Pressure distributes the General Pump 98210300; it is the identical Interpump-manufactured part regardless of which brand name is on the bag.
