Electric Fuel Pump Install
Hey guysI've run into a problem with my mechanical fuel pump on my 1980. I've installed a hybrid 22r and I had to change the thermostat housing since it interfered with my weber 32/36 carb (housing was blocking fuel inlet on carb). I put a later model housing on there which is at a different angle.
Now no problems with carb, but thermostat housing is blocking fuel pump inlet/outlet. I'm thinking of just throwing a block off plate on the head and running an electric fuel pump. Any recommendations? Thinking Holley, but which one? Would I have to get a regulator or could I buy an adjustable fuel pump? Is there another way around this dilemma?One other question just out of curiosity.
Does my truck have a fuel pump in the tank as well as on the head. Or is the pump on the head the only one? I appreciate any input. 1980 had the 2.2L 20R motor, but you said yours was replaced with a 2.4L 22R.So, here we go.only a 22RE (fuel injected) motor would have had a fuel pump in the tank, your's is an '80 which means no EFI that year anyhow. The 20R motor has no place on the head for a mechanical fuel pump, they had an electric one.So you wanna put on a block-off plate, make your own or steal one from a scrap EFI motor. If you had the AISIN carb you'd need to find a special low-pressure electric pump, cause the TOY carb takes 3-5 psi, and most cheap electric fuel pumps put out 5-9 psi, for carbs like weber and holley.But you seem to have the Weber after all, so just plumb a cheap 5-9 psi electric fuel pump from Auto Zone or Advance into the fuel feed line, with a cheap stock (new) fuel filter just before it to keep dirty gas from killing the pump.The stock mechanical pump has three lines attached to it. One goes from the pickup tube in the tank to the pump, one is a return line that carries excess fuel back to the fuel tank, and a short output line going to the carb.

How to Convert Any in Tank Electric Fuel Pump to an External Inline Pump: Cost: £35.00This video shows how an in-tank electric fuel / diesel pump can be modified to keep the existing fuel gage / sender unit and remove the faulty intank pump, replacing it with an easy accessible in-line fuel pump.Many vehicles, including. Jeff Smith: The simple answer is, yes, you can install a remote-mount electric pump and it will work. But there will be issues with this decision. I will assume you are going to convert to electronic fuel injection at the same time that you will install the electric fuel pump. A small, inline.
The mechanical pump is operated by a lever that sticks into the head and rides on a stamped sheet metal 'cam' that's attached to the front of your camshaft. This lever constantly pumps gas from the tank, all the time your engine is running.pumping faster or slower depending on engine speed. The pump has a fuel-pressure regulator inside it which tries to keep the carb supplied with an even 3-5 psi, by bleeding the excess fuel off and sending it back to the tank.that's the return line's purpose. Without the return line the diaphram in the pump would rupture, or you'd frack up the float valve in the carb.
I know i'm feeding you so much information your ears'll be bleeding in the morning, but i like to give you more information than you need, rather than less. Just plug or tie off the return line and you're good to go. But you gotta figure out which line is which, cause the return line hooked up to an electric pump will just suck fumes off the top of the fuel tank.Any cheap pump for a carbed motor will work fine. A fuel pressure regulator will probably not be needed.
Make sure the ground wire for the electric pump is grounded well, and run the hot (red) wire to any circuit that goes live when you turn the key on. (When the engine is running, the pump should be running.

Some seem to make a horrible moaning noise, but it does'nt seem to affect thier operation, it's just annoying.) One anti-theft idea is to run the pump off your auxilliary driving lights circuit. If you install driving lights on your front bumper, and flip the switch to turn them on just before or after starting your engine, fuel will flow. Iphoto 11 download utorrent for iphone. Anyone who doesnt know this will drive your stolen truck a couple blocks and the carb will run out of gas.
(Unless it's night and they find the switch to turn the lights on.)The best pump you can probably buy, (opening this thread up to endless debate) is a Carter. Just don't let the auto-parts moron talk you into getting an EFI pump, they put out about 100 psi to feed the injectors in an EFI motor, and you won't like that.Feel free to ask me anything in the future, i'll try to give you my best awnser. E-mail addy is on my profile. '84-'88 Toyota pickups are the only type of vehicle i own, and i know alot about them, having rebuilt/ fabricated almost everything imaginable. In the case of transmissions and transfer cases however, in my humble opinion, Mr. Marlin will always be KING.
Hey man, thanks for all the info.Couple of things. I replaced the block with a 22R but kept the 20R head (that's why I said hybrid 22R). I know that some of the 20R's had electric fuel pumps but I know for a fact that mine has a mechanical (hole in front passanger side of head) which is why it is interfering with my thermostat housing. I'm pretty sure that there is a pump in the tank as well as the one on the head since I know fuel pumps push the fuel better than pulling it and I don't think that fuel pump on the head would be able to suck fuel all the way from back in the tank. Anyhow, if I go with an electric pump I think 5-9 psi would be too high for the weber I've got (I think they recommend like 2.5-3psi). I have heard carter makes really good fuel pumps.
I will definitely look into one of those if electric is the route I end up going. If I DO have a pump in the tank, is it going to cause problems going electric? I'd like to have this truck running one of these days. Any other advice is, as always, greatly appreciated.
I've never seen a 20R head with the hole for a mechanical fuel pump, none of mine have the hole. Doesn't mean they don't exist, i just 'aint seen none.When i tell you there's no pump in the tank, don't argue, just nod your head and agree with me.
I have put an elect. Pump on my 83, and there are some thinks to keep in mind when doing this that have not been talked about yet.yup mount it in back, elct. Pumps push better than 'suck' and manual pumps suck better than 'push'.most important is this, if you were to roll it and the motor stop and not get to the key to trun it off the pump will keep pumping fuel to the motor and it will run out the carb vent.not a good thing.you need to put a switch on the oil presser port that will kill power to the pump if the motor stops and oil presser goes away.I had a carter pump and a reg. On mine and liked it.
