Mechanical fuel pump

[califkid_66]

Changed my pump last year and it’s not working anymore decided to open it up to see what was wrong
In the picture you have the sev valve  and the plastic one is the reproduction the plastic warped I don’t know if it was the fuel or heat causing that I heated it up to straighten it but it didn’t work

Maybe alcohol in the gas?

[jbcollier]

Yup.  Some premiums are ethanol free.

That’s it for me I’m installing my facet electric pump !!

Fit an inertia switch as well.

Yup.  Some premiums are ethanol free.

In Nova Scotia, the last available ethanol-free premium fuel was taken off the market last month. Ethanol in everything here, now.

Let us know how it goes. I've been thinking lately of switching to an electric pump also.

Do you have a general aviation airport near you?  Avgas is 100 octane, leaded, with zero ethanol allowed.  That's what I ran in 693R (yes, more $$$), but never had a problem.

If you aren't a pilot, is it hard to get general aviation airports to sell avgas to us? I have a regional airport near me, small jets to nearby states. I imagine the security there would frown on me driving over to the gas facilities. But maybe not; I haven't tried it yet.

According to Pure Gas, the nearest non-ethanol automotive gas is about 45 minutes away.

Depends on the operator.  Some look the other way and sell gas to whomever.  Larger fields (ie with commercial airline traffic are, understandably, a lot more restricted.)  Believe or not, lots of the smaller fields have self-serve...so...whomever pulls up to the pump can fill up.

YMMV.  I'm lucky, I guess, that my field has self-serve.  Caution though: the nozzle is BIG and the fuel flows quickly (typically, most GA planes hold 50-75 gal of liquid gold...and the standard size nozzle would take forever to pass the amount of gas to fill the large tanks...)

Kendo,  I see that you too are in Nor Cal.  For my home made race car I use Sunoco Optima 95 race fuel.  I have to drive a couple of hours to Fairfield to buy it in 5 gallon jugs.  They have a good selection of race fuels in stock.  There are other outlets in and around Sonoma Raceway/SF.

My S1, thanks for that link. I go to Davis fairly regularly, so that wouldn't be much out of the way.

I just reassembled my fuel pump and it’s working
I just noticed that the o ring was swollen and after a couple of days it shrunk back to its original size and it’s working perfectly
Something made my o ring swell and caused the fuel pump failure
I’m running 94 premium fuel it’s not supposed to have ethanol in it
Do I need to have fuel with ethanol or use lower grade fuel
The engine runs great on 94 I fueled 87 once and the engine didn’t like it

  Here is a good start for choosing a proper or better o ring . I pulled up skydrol because it’s the most nasty hydraulic fluid known to man. I believe if you will be happy.
