In talking with a few buddies, it seems that a late 80’s early 90’s Toyota Celica fuel pump will work for the pump. Haven’t found how much amperage it consumes yet. Hopefully it’s below 10 amps. Also a Dodge Neon throttle body is about 50mm which would be perfect for a single throttle body setup. Both these parts are dirt cheap online.
Another buddy said that he could probably get me in for some machine time to build some injector manifolds and the connecting plates for the throttle body (air cleaner and to split it to the two heads). That just about solves the two hardest parts of this project!
One of my buddies (Derek) also said I could borrow his MegaSquirt simulator board when it comes time to build my own MegaSquirt. I’m still debating if I’ll go with the MSI or MSII. There are benefits to both. I might go with the MSI because it’s cheaper.
For injectors, I’m thinking some sort of saturated injector because it is relatively low amperage (1.5 amps). However peak/hold injectors are a little more readily available… Also I’m having difficulty finding info on injector bung sizing.
I have a 1989 Honda PC800 which the fuel pump recently went out on. I checked everywhere and the fuel pump is no longer available through Honda (its actually a Mitsubishi fuel pump but can’t make out the Mitsubishi numbers). Anyway having a hard time finding an aftermarket or alternative fuel pump. Saw the information below and was wondering if you could recommend a fuel pump to purchase to get my PC800 back on the road?
Hello Paul,
I can’t provide good advice for a replacement non-Honda pump to drop into a stock PC as I haven’t really researched it. However, There are two PC800 fuel pumps available on E-Bay at the moment for a pretty decent price. It’s always a crap shoot with E-Bay when buying fuel pumps but it’s worth a shot. Another option is to ask on the IPCRC, the PC800 internet listserv. There is a very good chance someone has a known-good spare pump kicking around that they would be willing to sell you for a reasonable price.
Another potential option is to take your pump into a *good* autoparts store and see if they can match it. Personally, I’d try asking on the IPCRC if anyone knows of an alternate source for the pump or the Mitsubishi part number and, failing to find a new pump, ask if anyone has a spare pump that works and that they would be willing to sell you. E-Bay would be my backup option if nothing else panned out. Or if you want to get on the road quick, grab a pump from E-Bay and see if it works.
Hope that helps, Paul!
Cheers,
Douglas
Thanks for the quick response Doug. I was actually talking with someone at Autozone today via the phone and they said that since it was an electric pump that if I could find out the Flow Rate for the pump they could probably help me find another replacement. Also curious if/why I can’t use the fuel pump from an later model (94-98) but no one can seem to tell me if its just a matter of a simple mod to the later fuel pumps or if totally different. Anyway I gonna try the IPCRC as you suggested and had looked on eBay previous and it seemed like a crap shoot. One looked very old and no returns the other (after inquiring from the seller) was actually from a 95 model. Thanks again … looking forward to getting back on the road after spending $500 in repairs last year just to find out that its finally the fuel pump and all the other work (and money) was for naught.
Hi Paul,
Someone on the IPCRC should know if the various 94-98 model year pumps will work on the 89-90 bikes. My guess is it’s identical or very close to it. The flow rates (look in the PC800 Service Manual on page 18-24) are the same across all bikes. You might have to switch the electrical connector but I bet that’d be the only real difference. Looking at the microfiche, it appears that there were several different pumps over the years. I wonder if they changed suppliers at some point, thus leading to the different part numbers.
Good luck getting your bike back on the road! Mine is sidelined with front brake issues at the moment. It kills me to not be able to ride. Next week I should have the rebuild kits and be back on the road. 🙂
Cheers,
Douglas
