best fitting aftermarket out there.

The pin (& caps) were a perfect fit and came packaged with a light coating of wax and wrapped in wax paper it was completely protected from the elements!

Product as advertised.

SUPER fast delivery, Superior quality. I give number one.

Exactly as described. High pressure fuel pump is generally used on injected engines, low pressure pump for carbureted engines.

What an you say about flat washers? They are flat, round and the correct diameter. Thanks.

Great Product

Intake gasket SL71973 a good replacement for Lycoming gasket 71973, my mechanic and IA recommended it. The gaskets are working for me. A one time use gasket.

Of obvious high quality, shipped very promptly, A+

What expected

Prompt delivery and a good quality pump.

My first cylinder install and went very well, though, I recommend buying new nuts along with the cylinder purchase. Difficulty installing rocker arms transferred over from old piston, but prevailed. Insure you have Manufacturers Overhaul manual in your mind before doing and have available.

Replacement pump well packaged and now working to specification. Maybe I missed the information in the listing but suggest you state that the overhauled pump comes with gasket and O-rings. I ordered an extra pump to accessory case gasket.

especially like the e mail reciept

Installed on an M20-j. Pressure is right on the redline for the airframe. It’s well within specs for the engine. Worked as expected.

These look just like the ones on my engine. The last time I needed these, it was a pain waiting to get them. These are inexpensive enough to have some on hand just in case

Great parts and great price Ive been using Superior for years and have no problem using them as replacement for OEM

Perfect and the best price I can find

They look good, work good. All fine

The best pricing I can find! Thanks!

Your packaging not as beautiful as previously. Yku can enhancement for next delivery.

No problems except didnt have instructions for return of pump for credit.

This item looks es expected, nothing specil to coment

buenisimo

We were sent the wrong rings. Gave the model number of the engine and what material the cyl was made of. They told us what rings we needed.
