Intank fuel pump replacment.

Post by Weasel M29c » November 3rd, 2016, 10:21 pm

So my M151 did not have a fuel pump mounted to the block when I got it. Just a electric pump mounted to the fender. After 4 pumps over the last 5 years it was time to go a different way.

I cane up with a low-pressure in-tank pump. And now its built and will start testing it. So far so good.

Will keep you posted on how I do.

Just ain't the same as the good ole "tic-tic-tic-tic,tic,tic,tic, tic. :roll: :lol: :lol: :lol: Be real interested to see how it works out. That could be a worthwhile mod for someone wanting to stay as close to original as possible in the world of non existent NOS pumps. Now, if you come up with a solution for the coil issue..................... :roll:

Sound in the tank is more a weer now.

Up-date after about 80 miles I had the carb inlet valve leaking. I now have added a regulator on the tank. Think it was just to much PSI (about 11?) Fixed the problem and on with the testing.

Way too much pressure! 5-7 lbs. is spec., I prefer to stay closer to 5.

That's what experimentation is all about. somebody has to do it so the rest of us benefit from the results.

Would a fuel pump from the larger trucks work? Like....

Seems the depth is adjustable and not sure but are the mating holes universal? Edit - scratch that, looks like different number.

hi

most in tank pumps are not 24 volt and are for a fuel injected engine (high pressure pumps )
i think the Oshkosh pump is for diesel
below a other pump i do not know if it can be used inside the tank
a option below the seat

I think Aswayze used the Carter fuel pump inside the fuel tank, I could never find where that was safe.
