Bobcat 742 fuel pump

[Tvaughn762]

Hello y'all I'm new to the site and I need some help. I've got a bobcat 742. The fuel pump gave out and I need a new one does anybody know the Napa part number for it?

According to the book, the 742 has the Mitsubishi 4G32 engine, a quick Google indicates that that mill was used in the Lancer, Mirage, Cordia and Tredia models, among others.
Rock Auto has them from $14.20
NAPA has them for about $36

Check pics carefully, and bring the old one in if going to the store. NAPA often has parts for off road equipment; their site isn't playing nicely this morning so I can't search.

I was under the understanding that the 742 had a Ford motor in it. Is that not the case?

Yes, 742 is Ford. 742b has the Mitsibishi. You will be better off fitting an electric pump such as a Carter P4070. While you can still buy the OE style pumps the diaphragms get rock hard in a very short time if your fuel contains ethanol, even the 3% stuff in my experience. Another thing is the Ford drives the fuel pump via a cam lobe which can get worn down to the point that it does not stroke the pump enough to deliver fuel. Changed mine about 6 years ago and still happy w/ the results. Use a small power relay, run a fused 12v. source to it and then use a wire from the + side of the ignition coil to trigger the relay.

I would have to agree with Craig, fitting an electric fuel pump is a far better option. Just make sure that it is one that generates a delivery pressure suitable for a carburetor; 2-3 psi is about right.
Wire the pump so that it receives power in the ignition on / run position.

You are correct, the 742 has the Ford. The book I was looking at called them both 742 in the spec section, without the b designation and I missed that.
Sorry for any confusion.

Thanks all that solved the issue but alas more problems showed up I posted a new thread for that train wreck. Please see "742 won't idle up" for details. Any help is deeply appreciated
