Since my Dad and I both make our own biodiesel, I was woundering if the bio would deteriorate my fuel line and some of the seals in my fuel pump. My dad has a 98 chevy 6.5 diesel and it runs very well on 100% biodiesel, after we cleaned fuel tanks and replaced fuel filters. . i have heard on many occasions that they changed the way that they made rubber in the mid 90's but I dont know. I'm hoping that people out there are running it in their 1st gen. pickups. thanks

It should be okay in the '92 -- the '92 has some sort of nylon-like fuel lines, bfore that they had rubber fuel lines.

There was a link to a study in a thread on one of the foums here -- a college ran a couple of 1st gens on biodiesel for 50k+ miles. The only problem the '92 had was a deteriorated AFC diaphragm -- which seemed awefully strange to me, but all in all is an easy repair.

Just make sure that you are making good quality biodiesel.

 

Thanks. I wash my biodiesel to get out all of the "floaties" as I like to call them, then it gets filtered through a 5 micron filter. then poured through a kerosine filter, to the truck. I try to keep my fuel very clean. Thanks for the help, just an average 9th grader here trying to save a dime.

you will need to eventually change your fuel pump (check this group for "piston pump option")

the membrane will soften, then leak and eventually fill your crankcase with fuel !! Bio-D is a nice solvent, but not sure engine will like the 'submersion' method of cleaning
here are some good Bio-d links

This university has gone many yrs 100%BD in a 1st Gen (They mentioned the fuel pump issue at their Boise Utilization conference last year.)

 

Hey, I know exactly what your talking about when you say that it will soften the rubber. My wash tank usually gets the seal replaced every 200 gallons of fuel I wash through it. The seals get soft and start to leak. thanks for the links to the sites you gave me.
