Hi members.
I’m about to change my fuel pump in my 49 Chevy truck (235 ci). I e cleaned the old gasket off completely. When putting the new gasket I’m planning on using a sealant on both sides of the gasket. Any other special instructions I need to know? I don’t want any gas leaks. Installation seems simple. 2 bolts into block plus connections of fuel line. Thanks.

You could try to rotate the crankshaft (via harmonic balancer) until the lobe on the camshaft is a low-spot (might be hard to determine by finger-feel in the hole in the block?).

I wasn’t aware that the arm of the fuel pump had to hit a certain low point on the crankshaft.

What I described is not necessary.

It might make it easier to install the fuel pump - the arm on the pump will not be pushing against a "high spot" on the cam lobe.

By doing as Tim suggested, it relieves some tension on the pump arm thus making it a bit easier to get the bolts started. As he also said it not necessary just requires a bit more fiddling.🛠

Its a good idea to glue the gasket to the pump with gasket cement or trim cement. Let it dry good. that way it can't shift on you as you are installing it. You can put a light film of RTV on the other side to be sure of no leaks.

The gasket most likely will not leak anyway. It came for the factory without any sealant. That is if the gasket is the right material to work with ethanol.

Which gasket are you talking about, the one between the pump and the engine block, or the one for the glass filter dome on the pump? Neither one needs any sealer at all. By introducing sealer into the mix you're more likely to create a leak, not prevent one. The pump-to-block gasket won't leak gas anyway- - - -it's there to seal oil. Use a little brush-on Permatex if it makes you feel better, but it isn't necessary as long as the sealing surfaces are clean. The cork gasket for the sight glass doesn't need any sealer, and definitely don't use some sort of rubber-base stuff like RTV! Any residue will end up in the carburetor, clogging up jets and/or causing flooding.

Been running a glass filter fuel pump on my 49 216 for nearly 7 yrs and 23K miles. No leaks and no sealant on the glass bowl gasket. I did use alittle Aviation permatex on the pump to block gasket, mainly to hold it up while mounting the pump.

This makes sense Hotrod Lincoln. I’ll take your advice. Thanks.
