Guest mtnman Posted July 29, 2015 Share Posted July 29, 2015 I saw the discussion on the Airtex E-8011 6 volt fuel pump to prime a car after storage. I was wondering if you had a pic of your setup? Also I was looking into revamping my 6 volt to an 8 volt. Do you think that pump will work okay on 8 and not be too much pressure? Link to comment Share on other sites More sharing options...
Steve_Mack_CT Posted July 29, 2015 Share Posted July 29, 2015 No pic but if it helps I can tell you I installed that model on my packard. Looks like an in line fuel filter. Too heavy though, for fuel line to hold it. I was lucky in that the frame where the fuel line runs had a hole already there, so I mounted the bracket without drilling. The mfg. Wants you to mount as close to the tank as possible but I found up front worked out ok as well. I would contact the mfg. On your voltage question. One last tip, these are available for a lot less from Napa or likely the other parts chain stores, antique parts vendors charge more, as I discovered after I bought mine.

ply33 Posted July 29, 2015 Share Posted July 29, 2015 Just looked and you can get that pump on Amazon for about $26. A couple of cautions: First if your gas tank is like mine, probably the best grounding for it is via the metal fuel line. If you cut that and use rubber hoses to insert the fuel pump you may have issues with your gas gauge working correctly. Fix would be to run a grounding wire to the tank (probably not a bad idea anyway). Second: The only reasons I've heard of for switching from 6v to 8v is to cover up electrical issues. In my opinion it is far better to fix the issue than putting a bandage on it. If it is poor starting, it could be old or undersized battery cables or worn starter bushings, etc. If it is lighting then it is likely corroded wiring, connectors and switch contacts. In any case, you should fix those regardless and if you do you may well decide that you don't need to change to 8v. Link to comment Share on other sites More sharing options...
Curti Posted July 30, 2015 Share Posted July 30, 2015 You may want to check out the Airtex E8902 2.5 - 4.5 psi 6V. I would recommend finding the grounding problem with your car as opposed to converting to 8V Link to comment Share on other sites More sharing options...
Guest MORRISGAUGE Posted July 30, 2015 Share Posted July 30, 2015 I am not an expert in the wiring of your vehicle, but have some trepidation regarding a voltage "boost" solving any real issues. Chassis voltage can range on a 6 volt system and the increase in voltage hardly seems to be much of an improvement. If there are existing ground issues, etc. they will still be there regardless of the proposed 30% increase in voltage. Just my 2 cents. Link to comment Share on other sites More sharing options...
Taylormade Posted July 30, 2015 Share Posted July 30, 2015 I have read conflicting reports about using this pump (Airtex E8902) with a positive ground car like my 1932 Dodge Brothers DL. Some say it works, others claim it won't work with positive ground. Anyone have any real world experience with this? Link to comment Share on other sites More sharing options...
Steve_Mack_CT Posted July 30, 2015 Share Posted July 30, 2015 Well, first I am not sure of the difference between the two model numbers listed above, they sure look alike, I have since sold the car but may well have had the 8902 which seems more common, maybe an updated version? Anyway I had same concern about positive ground. I called airtex who assured me that it was for vintage applications. I had no issues and found it was effective as expected. Grounded to the frame. Used for priming, on hot days and even at highway speed and I did see the difference. Link to comment Share on other sites More sharing options...
West Peterson Posted July 30, 2015 Share Posted July 30, 2015 Use the 8011. If you think you need more voltage, as mentioned, do not do the 8v set-up. The most common problem I seem to come across is that too many people have used a 12-volt battery cable instead of the required 00 6-volt cable. Also, clean all your connections. That should solve most problems. As Steve did, I've mounted my 8011 up near the front, and it works perfectly, and has been working perfectly for several years. It is ONLY turned on if the car has been sitting for more than a week, or during the few times it wants to vapor lock while driving. As soon as the "stumbling" goes away, I turn off the fuel pump. It usually only takes a few seconds to pump some cold fuel into the system. Link to comment Share on other sites More sharing options...

Some say it works, others claim it won't work with positive ground. Anyone have any real world experience with this? I have the 8902 on four Auburns which are 6V + ground. They are mounted about 2/3 of the way back on a frame rail. The other two cars have vain pumps and when they fail they will be replaced with 8902's I use them in tandem with the mechanical pump.
