Just installed a Mr Gasket 42s fuel pump... .a couple of questions

[grubsie]

Does this pump stop gas flow when the bike is not running or do I have to get into the habit shutting off the petcock?

 

Anyone had one of these pumps fail? I switched to it because the points on my OEM pump are already pitted pretty bad and this 2008 RSV has just under 24K on it.

I am not sure if that model Mr. Gasket has an anti syphon valve in it or not, but for my piece of mind I would get in the habit of turning the petcock off, better safe than sorry in my book.

I ran that pump for a couple years. I never had issue with the siphoneffect. But no far as I k oe the pump dont have the check valve. If I parked for long tims say over night I closed off valve.

That pump doesn’t have the anti siphon. I had hydro lock with the OEM pump once. Fortunately no damage but I got in the habit of shutting off the fuel every time I turn the bike off. On another bike I used the 42s and had no problem

Hmmm. My biggest concern is the longevity of this pump. It's gotta last longer than the stock one, Right?

 

Am I reading the specs wrong? It's stated that this pump prevents vapor lock. This is the description over at Summit Racing:

I was able to use the stock clamp because I didn't use the filter that came with the pump (have one under the driver seat just behind the tank) and used a 3" brass nipple with a union and fuel line fitting so the tips of both fuel nipple are almost even. The stock clamp fits tightly even though you see gaps in the pics I am posting and gap in the clamp for the black plastic extension on the stock pump clamps very nicely on the brass fuel pipe I put on the mister gasket. I did this because I am going to replace the points on the stock pump and use it as a spare and wanted it to be plug and play.

 

For part of the plug and play, instead of splicing the stock pump connector onto the MR Gasket, I cut the 2 pin clip off the old pump and soldered on waterproof 2 female pin connectors on to it. (like old hondas and such used)The plugged it back into the the one on the bike. Then I soldered on the waterproof male pins onto the wires of the stock pump and Mr Gasket pump so that either one can plug into the female pin connectors that are on the stock 2 pin connector.

Mine had 30,000+ Miles on it when I got rid of the bike.
