A big thanks to djh3 for this excellent article on converting to the Mr. Gasket 42s fuel pump.

 

Replacing OEM Fuel Pump with Mr Gasket 42s

 

Parts Required

 

· Mr Gasket 42s

 

· 1ea 1/8 in. x 1/8 in. Lead-Free Brass 90-Degree MPT x FPT Street Elbow (lfa-712

 

Home Depot)

 

· 1ea 1/8 in. x 1/8 in. Lead-Free Brass 90-Degree FPT x FPT Elbow (lfa-700 Home

 

Depot)

 

· 1ea 1/8” Brass hex nipple. (lfa-714 Home Depot)

 

I took the Mr Gasket 42s fuel pump and a dremel tool and cut along the edge of the mounting tabs. Cut

 

carefully so as to not damage the pump. If you see sparks your to deep.

Once you get a nice line across both halves, take a flat bladed screwdriver and insert into the line you

 

have cut. Give it a little twist, you should hear a pop or crack sound of the plastic separating. As you

 

can see in the second picture I used the provided fuel filter also. I needed the length to get back to the

 

supply side anyways and it was free and just put a second filter in the system. I figured no harm.

The two pumps are fairly close in comparison. The OEM is approx 2” in Diameter and the Mr Gasket

 

is 1.5” once the plastic case is removed. I looked for a 1.5” adel or “P” clamp but couldn't find one. So

 

I use good old plumbers strap and some black electrical tape and heat shrink to make a bracket to hang

 

the pump from. You will probably have to rearrange the line to the carburetors a little to keep from

 

kinking it. I had to move it to the outside of the plastic thing it runs in behind the fuel tank coming

 

towards the pump/seat area.

Once its all settled in I tightened up the clamp and double checked to make sure I didn't have anything

 

rubbing or chaffing. Pump against something or a fuel line against something that could later give

 

problems. I did install some anti-chaff tape on the fuel line on the opposite side as it was laying against

 

a bracket slightly by the water tank. I found it easiest to remove both side covers, the forward cover

 

that they connect to and the overflow tank so I had room and could see what I was doing, On the final

 

fit with the front cover installed, make sure everything fits inside.
