Intank fuel pump

RE: Re: RE: Re: RE: Intank fuel pump

if you notice any difference when you turn off the switch, you have a leak. trust me on this. air will come in where fuel will not go out. the booster pump is perfectly capable of supplying fuel, but it is pulling from the tank through at least 5 joints, maybe 7.

Ive been drive my M35A2 for years now with a nonworking intank pump. I took one out of a parts truck and have seen no difernce in how the truck runs.

What I found to be the biggest problem with a non-working in-tank pump is how long I have to crank the truck before it starts. 15-20 seconds w/o a pump. 1-3 seconds with a pump.

As far a driving, I can't say. I haven't had a reliable pump long enough to test this.

Even with out the pump, Mine has never needed more than a bump of the starter to start. 1/4-1/2 of a second maybe,unless its cold and that is only because my bats are weak.

I purchased a new intank fuel pump from John Murray and have no problems the pump has been installed for 6 months. Stay in contact with John if you are not satisfied. He does not make the pumps and if there is a problem with his supplier he needs to know so he does not use that source again. Lets face it guys, NOS is new OLD stock. Remember some of this stuff has been sitting around on shelves for a few years. I bought an NOS magneto for my mule in a sealed box dated 1965 in 2007. Guess what no spark, we had to open it up and polish the points before it would produce a spark. It still cost $160.00 the spark was priceless.

If the truck wont run without the intank pump working , Does this mean that the supply pump on the side of the IP is'nt working?

PUMP

I dont think thats the case .my montego (diesel car) WILL NOT run if the fuel pump is not working . and non of the FIVE trucks I have will run pumpless iether....(enuf revs? they might?)..but as I said we once had a Ballache fitting (the) spare pump I carry! (as you do!?) at the roadside to re start to get home..and that because I had run low on fuel..as I posted once before...((grind grind trhe round the weld..remove innards CLEAN SAME!..all the bits off the dribe magnets..rebuild (and then) EVER SO CAREFULLY, and 1000000% WELD it up again..now it works fine again..(err did sorta raise the hairs on the kneck first time starting..)..THAT WELD MUST BE GOOD> (do NOT do this at home???!!)

It took 6 weeks but I got the new pump for Olympic Controls today.

 

[emmado22]

Im all about saving a few bucks, but come on! Cutting open the pump, fixing the problem, and them rewelding it? I hope your a REALLY GOOD welder... Whats more expensive, a new pump, or a new truck because your welding skills werent what you thought they were?????????????????????????????

I'll buy a new pump, thank you....

so just out of curiosity, because i have to order one of these pumps from the same people, how does the pump work? was there any trouble putting it in? and did it pump fuel all the way to the final fuel filter?

 

[southdave]

My pump went out about month or so ago, went to the box o crap there was pump in there made by Parker 24 volts it runs at 30 psi had to change the wiring but OMG did make a difference.

 

[adv789]

where did you get that pump? and what wiring changes did you have to make?

 

[Jeff Cal]

Is this for the M135 in your photo?
If so I have NOS pumps for $85.00 plus shipping.

The M135 at our VFW Post needs lots of TLC, I pulled the fuel pump assy to see why it's not working (has 24V at the connector) and it's fouled with bad fuel. Worst I've ever seen, looks like bearing grease packed in the bottom of the pump assy. If I need a pump, I'll contact you, I just wanted to test this "link" to see if this message board works. I'm new to the forum. Please reply.
Thanks in advance,
Jeff

GL -Big Box Of CRAP- it listed 5 racor filters in which none were it. But it proving to be a usefulIt looked very similar to to exiting pump but had replacable brushes alittle bigger though it was kind of stop gap repair. As for the wiring it had some funky 3 prong connector on it so I cut off put in line fuse in it added grommet to the opening. works great fuel leaks out the #1 secondry. but now it run really welll on UMO

@southdave, 30 psi? I would be careful with that. Stock pump output is 5-7 psi according to the T.M. I read. I'd hate to see you blow a line out in the engine compartment or something and start a fire. Just sayin'.
