## Questions & Answers

**Q: Would this work ok on a TBI install, or would it be too much psi?**
A: It does not have an internal regulator so you would either need a filter/regulator combo or a regular at the fuel rail. I have it installed with a sniper EFI TBI unit that has an internal regulator and it runs at 60psi.

**Q: What are the thread size for the inlet and outlet?**
A: 10x1.0

**Q: So you wont ship to california?**
A: This seems to be an Amazon problem, stemming from how the listing was initially created.  Since this is not technically a 'Replacement part' and is a performance fuel pump, it falls under CARB regulations.

**Q: Do this fit a 2014 Yamaha 250 four stroke**
A: I don't really know about motorcycle fitment. I do know that the Walbro pumps are poorly made and I returned this one. Delphi makes better pumps, whether they make them for motorcycles I do not know. Best thing to do is go to the Delphi web site and plug in your application to get a part number. Or Google it "Delphi fuel pump Yamaha 250CC" or the model number of your bike.
