MECHANICAL vs. ELECTRIC FUEL PUMP on 2F

[LRS30]

PRO's CON's on each for a 78 2-F FACTORY CARB What are your recomendations, if electric is used with type/brand have you used and did you use a fuel pressure regulator and set on what.. Or Should I stick with the stock mechanical? Lots of questions but really curious.

The stock mechanical pumps are great, they last forever and run the PSI that the OEM carbs need. Carry a spare if you are worried about s***ting a pump on the trail

Yhea I am running a Mechanical pump on mine, took it wheeling this weekend and ran flawless, my brothers mechanical crapped out earlier in the week, and we popped a mechanical one in to get him home, and decided to run it anyway, and after climbing the hill out it died, so i ran to the auto parts store and bought another to get him out of the hole popped it on and guess what it.. It got him home but also started acting up as well.. I'm curious just to see if anybody is running a electric with success. I plan on carrying an electric one in my survival pack just as a back up, but wanna make sure it will perform enough to get me home.

If you are having THAT many problems with a mech fuel pump thats telling me one of 2 things.

1. Your fuel filters aren't working right and fouling the pump.
-Replace the fuel filters. They are cheap and easy to swap out.

2. You're using a s***ty aftermarket fuel pump like what Checker sells.
-Get an OEM fuel pump either from the dealership or go to Napa. Napa carries a Kyosan-Denki (OEM Brand) fuel pump in a Beck Arnley box. WELL worth the money.

elec

Lots of vehicles using electrical. I used em on a couple of my cars in my teens I cant see why it wouldn't get you home although having said that I dont see an advantage in swapping you dont need additional fuel flow or anything

Stick with mechanical, keep the electric in the toolbox for a spare.

I ran an electric for a few years when the original mechanical went out. It started to have intermittent issues and didn't seem to supply enough fuel at WOT, so I went back to the stock mechanical and tossed the electric in the spares box.

Not a huge deal, but worth considering is that if you have a mechanical fuel pump, the only 2 things that need 12v for the truck to drive is the coil and the idle solenoid. That gives you an impressive range if your alternator were to fail.

I think the problem with the electric pump's where they would'nt flow enough, I bought the cheapest they had jsut to get him home, like I said it got him home but still is'nt right, we have the original on order, was just curious if anybody has used one with success like i said previously.. We had 2 pumps go bad one in my buddies PATH FINDER and my brother's FJ.. It was an all night ordeal just getting the NISSAn out of the hole was still fun....Stupid Nissan...

mech

Having said the electric will work (and they will) I personally would not install one when the mechs last forever it seems

Now the electric might be a good lightweight spare like you said


Have you considered the third option---A squeeze bulb?, but you need a passenger to operate it--but for a NISSAN owner that's the way to go

I told him to just leave the NISSAN where it died, and the wood's recovery team (vandals) would take care of the rest.....

After having trouble with the OEM mechanical pump i decided to switch over to a Mitsuba fuel pump.

No problems in the last 20 years........and it does have a filter element that can be changed if needed.

.........but i still carry a mechanical as a spare........

Any Year/Model/Part Number you would care to share?

i've heard they can rob at least 5hp. fan robs as much if not more. maybe not noticeable on a big engine... but that's 10 hp that you could run off your battery that is charging anyway.

I'm gonna have to quote you on that one.

No way a fuel pump uses 5hp. Maybe 1/5th of a hp.

If I had a stock carb I'd be running a stock pump. It just doesn't make sense to us anything else unless you cannot get a quality one in your area.

For $43 you just cannot beat the reliability. Plus, amazingly will bolt right up.

The only online source i found: http://www.limora.com/pdf/19717.pdf

I bought it at Racimex.de - Alle Produkte rund ums Automobil, Motorrad und Jetboot but i guess they dont sell them anymore.

 

[Pighead]

Pighead has never had a problem with the stock fuel pump...sees absolutely no reason whatsoever to change to electric. Unless one goes EFI.

I use a Carter electric fuel pump on my 2f for about 8 years now, and i instal a fuel regulator (carter) set to it's lower pressure (4-5 pnds), I got no spliling issu or other trouble with it since then.

 

[Cruisertime]

I stuck a Mr.Gasket 12S on mine. Freaking mech pump went up in parking lot. I had a pressure reg sitting in box already. I have another factory pump ( NAPA BA )sitting in tool box now.

I'm not aware of the brand electric pump I've got (PO install, judging from everything else the PO did, probably cannibalized from another truck) but it's noisy, and not-so-well wired in. Both mechanical and electric do the job, but the mechanical ones last forever. It's really up to you as for the final choice, but I'd say that if you plan on keeping that 2f stock, the OME pump and carb are designed for each other, and you'll get the best results by keeping the mech.

I had 2 different mechanical fuel pump arms break off inside my oil pan on my last 2F. No idea why....

It happened because you were not running the spacer between the pump and block. I also vote for mechanical. I am still running the original pump in my 79 and just carry a spare for when it dies one day.
