283 small block 57 Chevy Bel Air, fuel pump push rod
Hi Guys, My fuel pump is running at a low pressure on my 57 Chevy BelAir
so I want to remove it to see whats wrong, BUT I was told that the camshaft push rod that works the pump can fall into the sump when the pump is removed?? is that correct ?, if so, how can i stop this happening? also,,
Whats the average life of these pumps, and is a pump repair kit worth the hassle??
The fuel pump rod will not fall into the sump.Your gas tank strainer may have collasped giving you low pressure.How old is your pump 10–15 years.They are fairly cheap to buy.If it is that old start with that first,or pull the gas tank sending unit and check the strainer first.Fairly easy job but you may need a new gasket as they get quit brittle with age.If the fuel pump rods slides down and contacts the fuel pump,block backingplate push it back up into block.If it won't stay pull the backing plate off the block take the rod out put a glob of heavy grease on the rod and then put it back in the block that should keep rod from sliding back down.re-install backing pate install the pump and thats it.I just had to change the pump on my 67 camaro and had to do this.
Hi Buddy, thanks, glad the rod cannot fall into the sump! did your pump just pack up, and you broke down, ? my pump is not very old, about 9 years now, withy little milage use, about 10,000 miles only, the tank filter has been inspected and ok,

What do you call low pressure? 4–5 psi is all that is needed. What psi is your pump?
Hi, its about 3 lbs, on a test gauge, filter glass bowl never looks full?
whats the average milage life for this type of pump? Regards Johnny
My problem was low pressure as it would take about a minute of cranking to get the car started.Then one day in the garage the car would not start,I looked into the seethru filter and no gas was in it.Changed the pump and that fixed it.Goodluck
So change the pump already!!!!!!!
Hi Guys, Thanks, new pump fitted, now a full fuel fuel bowl! and the push rod did not fall into the block! Thanks Johnny UK
See now that wasn't to bad a job to do.I have owned my ole 57 for 40 years and have done about everything that needed to be fixed.
did you get the coolant passages in your block cleaned out ? and have you installed new freeze plugs?
Hi Guys, well thats a surprize, what a memory, re my freeze plugs, thanks for asking, firstly I am no kid, I am 65, and waiting for a hip replacement thats giving me hell, ex UK motortrade mechanic for 40 years, but no experiance of working on American cars, thats why I ask you guys first! so,,,I have owned my 57 2 door coupe pillerless since 2005, after waiting 49 years wanting to own one since i was a kid! SO,,,,, I firstly removed the leaking freeze plug, the one above the oil filter,no problem, and strangley the inner block was sludge and rust free, except for the usual rust attached to the block as expected, I could get a flexi piece of wire through the whole inner block! so it must have been a week plug from when it was fitted back in 1999, BUT to be safe, I removed the starter motor, and the plug behind it, again it was as new, so i replaced both with brass plugs, with the special tool my local garage lent me, easy, I washed the block out many times to be sure all was ok, then I replaced the anti freeze with a 50/50 mix, and thats it! some you win!! some you dont, I just hope the ones behind the gearbox are ok, but if not, I will take the box out, My thanks to all in America, I was in Florida last year, Melbourne, great time, great people, great weather, Regards Johnny
when replacing a fuel pump in my 57 chevy I have trouble holding push rod up when I install the new pump. Any suggestions
Ken, use a few dabs of heavy grease to hold the rod in place.
