TUNTROLMechanical Fuel Meter 7 to 20 GPM Aluminum Digital Diesel Fuel Flow Meter For All Fuel Transfer Pumps,Black,4-Digital Batch Display (1")

I purchased this cheap junk Tuntrol meter. Upon delivery I noticed how on the box it boldly states how the meter has been "factory tested prior to shipment to ensure the highest quality". What a big load of BS. Installed the meter & pumped 2 gallons of gasoline through & fuel started dripping out of the back of the meter. I found that the meter has 2 very small cracks in the back of the housing so it's obvious it was not tested as touted on the box. Then I figured I would simply return this one & purchased/order another cause surely it must be a good meter as the amazon reviews state. The 2nd meter arrived & I went through the hassle of removing the 1st junk meter with fuel gushing out & making a nice mess only to find out the 2nd meter doesn't leak but registers .6 gallons for every actual gallon pumped!!!!! BTW- There is basically no instructions that provide any install or trouble shooting, calibration, etc info included. I slowly turned the "adjustment" screw all the way in & all the way out with very little change to calibration or fix the issue. Just so you know- if you need any product support from whoever actually makes this fuel meter you will NOT get any. No phone number, no email, no address provided. Even went through amazon to receive product support & guess what....I got zero response. Oh the joy! So the 2 cheap junk meters are being returned. I ordered & installed the real deal USA made "Fuel-Rite" meter. Do yourself a big favor, save the disappointment & frustration just spend the extra money & buy a Fuel-Rite meter that's sold & backed by a USA company. Always best to support your fellow USA companies/people!!

Not So easy to install....So, after to figuring out ,on and off ,(4) times using the proper amount of winds with av gas plumbers tape, and pipe dope . Took me and experienced mechanic a few hours of playing around trying to twist the face in a position that is viewable. Be patient. Time will tell how reliable and accurate this meter actually is.

Perfect fit would tecommend
