Electric Fuel Pumps

Post by topellis »

I have been thinking about replacing my mechanical fuel pump with an electric one and have read a number of differing ideas and I suppose looking for some direction and the supporting thoughts. To me the main reason I wanted to replace the mechanical one with an electric one is to prevent vapor lock that I can get on real hot days, remove the possibility of gas getting into the oil if the diaphragm fails and go to what I "thought" would be a more reliable system. Reading some on the topic though..... I have seen some say the electric pumps don't last that long and some others only use it to prime the system before starting. (I thought that is what the lever on the mechanical pump was for?) I seem to remember the pumps need to be regulated to 4.5-5.5 Lbs or so for the carburetor. I have seen a few Facet pumps on ebay and also have seen these http://www.ebay.com/itm/24-volt-FUEL-PU ... 5a&vxp=mtr

Just looking for opinion and rational behind it. I have rebuilt my mechanical pump and run it for several years with no problem. Looking at cost, I saw the new diaphragm kits for the mechanical pumps and the they were somewhere around 75.00. The new electrical pumps that come in what looks like kit form on ebay listed above is less than that.

Thanks,
Mark

Ive been running the same holy blue reg and a carter 24v pump(looks like the walbro) for 11years and how long it was on the truck before? I don't know.
as a precaution I carry a spare(walbro) pump and my jerry can is a wayjax (German type) with a recessed valve so I can gravity feed the carb if both pumps die.

this past summer I suffered from vapor lock, happened at the tank. it took me some time to figure out what was happening but when I disconnected the fuel line from the pickup on the tank I heard a whoosh the fitting got wet then I was good to go.

I run that facet pump without a regulator and it works fine. I do have the modern needle on the carb inlet that helps it from flooding the carb.

Napa sells the facet pumps. They list a 24v on the website.
