Hi sir I watched ur video on hiw to install a fuel pump on me truck I
seemed to have let the push rod fall I was wondering if u could let me know
how to get it back up so that I can install pump correctly

MudRFunR says:

I plan to keep the videos coming as long as I’m on this side of the grass!
Thanks for watching, hope you subscribed.

MudRFunR says:

Good to know, thanks!

withered6 says:

Saved my bacon pointing out that pushrod inside there. Thanks man.

MudRFunR says:

Sorry, I’m confused. Your S10 has an electric pump so it must be fuel
injected. When you say carb, did you mean throttle body? Anyway, an earlier
type throttle body is similar to a carb but has either one or two injectors
on the top, facing down into the center of the butterfly. Have someone
crank the engine and look to see if fuel is spraying down from the
injecto(s). I will send a PM with some videos that might help.

Fletcher Clark says:

So I have a 85 S10 fuel pums been replaced carb filter been replace it was
running just fine yesterday yhe ground on the pump came loose an that made
it not start I reconnected it an it was fixed got it home just fine.. now
today it hasn’t wanted to start at all turns just fine and I hear the pump
running an when I put gas directly into the carb it starts but can’t seem
to to have it start . Any ideas?

Duran Suffridge says:

Thanks for getting back to me and you’re really cool to reply to everyone I
hope you keep making videos , we all appreciate it

MudRFunR says:

There is no need to prime a gas line. If it takes too long to start, then
you could squirt a bit of gas in the carb before starting it.

MudRFunR says:

The first thing I would do is take the air breather off and see if the
choke is closing or try giving it a small shot of gas in the carb and try
again.

I just got a 1983 camaro v6, drove it home 100 miles just fine even made a
pit stop for food. I go out today and it cranks and acts like it wants to
start but wont turn over. Could that be the fuel pump? If so where is it
located? Hard to replace?

Duran Suffridge says:

So how do you prime the pump after putting a new one in to get the gas to
the carb to get the mechanical pump started

MrETOWNLUNCHBOX says:

It sure was thanks for the help mudrfunr and duran i really appreciate it!

MrETOWNLUNCHBOX says:

Yes it was in the line/carb with the spring thank you

MudRFunR says:

The only place that your Monte should have a fuel filter is in the line
that runs bewteen the pump and the carb OR some stock carbs have the filter
inside the carb. Both are easy to remove. The inline filter is a couple of
clamps OR follow the line (from the pump) into the carb. If the line is
screwed into a larger fitting, then there could be a filter in there.
(careful, there’s a spring behind the filter)

Duran Suffridge says:

To the comment below about the Monte Carlo my 79 camaro is the same. It has
no in line fuel filter under the car like normal cars. Instead it just has
one on the fuel line as it goes into the carburetor

MrETOWNLUNCHBOX says:

Thanks! My 1976 monte carlo wont start not getting any fuel. Now i’m not
sure if its the pump or fuel filter my problem is that i cant find the fuel
filter any idea?

MudRFunR says:

Good to hear, thanks!

SilverHaze53 says:

Awesome vid. Thanks for the help.

MudRFunR says:

Anytime, glad to help! Theone thing that I did not mention on the video is,
if it seems to have too much pressure on the pump spring when installing,
check how far the rod is going into the block. If the rod won’t go up far
enough, you may have to turn the engine over a half a turn.( the rod should
now be on the low side of the cam lobe)

Robert Allen says:

Great video. Has been a long time since I have done this and now my 71
caprice has this prob. Been idle 2 years. I needed to remember how to do
this task. Its coming back to me now that I watched. Thanks again.

xsmokedoutx says:

Don’t feel bad I did the same thing lol Trying to save a few bucks

MudRFunR says:

Is it flooding before it stalls? Dirt in the float needle (carb) can cause
it to flood. A mechanical pump will usually work ok cold and fail when the
engine gets warmed up. When you drive at speed limit and step it down, does
it sputter and clear up or does it just keep bogging? Hard to diagnose
without hearing it myself. A fuel pressure test should tell if the pump is
faulty. Test cold and test again warm. Not sure but I believe it should be
5-7psi. (not sure if that psi is right)

7starpak says:

thank you soo much

MudRFunR says:

@boaterbil I have been told this before, but this block like others I’ve
seen don’t have a bolt hole there.

MudRFunR says:

Have you taken out the electric pump? If it’s still in the tank you have to
take out the fuse for the pump but it will not get good fuel flow without
removing the electric pump. If you are using the mechanical pump, it has 3
size lines and so does the tank. (3/8″ 5/16″ 1/4″). The small line from the
tank should be going to a canister. Leave that on there and plug off the
small one on the pump.

MudRFunR says:

I’m not sure if I quite understand. I believe the Ford pump is similar the
a Chevy. The rod that goes into the block is between the cam and the
plunger on the pump.

Adam Carter says:

So I have 1979 chevy truck 3/4 ton, 2 wheel drive,305 egine,4 barrel
carburator,and I am not getting fuel through my lines to my carburator my
buddy replaced my fuel pump still no fuel going to my carburator

MudRFunR says:

@Thegarmendia Another great idea! I’m learning a lot from others comments.
Thanks and Enjoy!

Samina Sana says:

Hey I bought a 1983 chevy 1500, its a 350, edelbrock, and it needs a new
fuel pump. You sound really profesionall and I was wondering if I have to
empty the tank, or if there were any other steps

juggalo450 says:

@MudRFunR ok i gotcha this car has been sitting for ten years sothe rod is
being hard to come up but tge pump came out easy

MusicLibrary says:

I have an 84 GMC jimmy with a 350 engine and the the first hose to the left
that connects to the fuel pump keeps breaking when i go offroading ( when i
rev the engine alot) i’ve replaced it many times , how can i prevent it
from breaking again ?

RisD16 says:

Hi…my hubby says thanx for sharing….what do you do if the rod comes out
and you cant get it all the way back in?

MudRFunR says:

@juggalo450 The (spring loaded) plunger from the pump slips under the rod
that’s inside the block.

MudRFunR says:

@Diabloshell If you have a leak in the fuel line (from the tank to the pump
) it cannot suck any fuel. Even a small leak will cause the fump to suck in
too much air. If not that then…Are you sure the pin didn’t shift out of
place when you tightened the pump in place? And this may sound dumb but is
the rod in the block at all. (speaking from experience, I have left it out
once)
