piston LP question

[mprmn08]

Im lookin at gettin a piston lift pump for my truck but wondered if there was anything special i have to do to put it on? Is a high pressure pump? and if so do i have to put a reg. between that and my IP or will the IP the way it is handle the higher pressure? thanks guys.

Get the low pressure pump, only puts out 15-16 psi, no regulator needed. You need the spacer, line, and gaskets also. You will need to cut off the insulation from the tappet cover to install the line. It hits if you don't.

is there a way to tell if its a low pressure one or not? also if its not is the reg. the only thing i have to add in other then what ptombs said already?

[PToombs]

Check the part number, someplace on here are all the #'s for the upgrade.
Yup. Out only difference between the 2 is springs and piston size on the inside.

ok, so im not too smart where do i grind im doin mine this friday mornin. i got all the parts i think,pump,gaskets,spacer,washers and line but now i hear i got to grind?what?

[fergavs]

Its just grinding/cutting some of the insulation off the side of the block. Straight above the fuel pump (you will be able to tell once you have the new fuel line) you need to remove some material so there is room for the new line. Its fairly minimal and minor really. Just put the line in place on the pump mark the offending material and remove. Obviously if it sound/feels/looks like your grinding cast iron you have gone to deep.

I would not try to go in there with any type of grinder, cutoff wheel or power tool of any kind. The VE return line is in there somewhere and cutting that would definitely ruin your day. A utility knife or similar works just fine.

ok so i got every thing cleaned off and tring to put it together and the line adapter is hitting that cover with about 1/4 needin to be up against the block what now

[PToombs]

Did you cut off the insulation? It's like hard plastic, then foam or something underneath. I cut mine with a 4 inch grinder, with a cutting wheel. When I saw sparks I knew I had to move a little. If I had to do it again, I'd cut it with a knife like Ace said. I didn't realize it was plastic at the time. It did cut pretty good though.

ok so is seein foam good or bad? no cast yet just foam

[PToombs]

Foam is good! just cut it out until the line fits. The tappet cover is stamped steel, like a valve cover on a car. Older car.

[TWorline]

Seeing foam is not a bad thing. What you are getting rid of is sound deadening material from the lifter cover, which is tin not cast iron. You really only need a slot cut in it big enough to get the top of the pump and fuel line into. I did like Pete did, used a 4" angle grinder and went from the bottom of the lifter cover to the top and ground till I saw sparks.

ok thats good cause i got to go more in and over i like my grinder

[randyswelding]

ok so its in a lil tight for the fuel line but, it is alot smoother idalin and an easy instal thanks guys
